BSCI'24: Best Student Paper Award

02.07.2024

Best Student Paper Award at BSCI 2024

Our publication "On the Impact of Network Transport Protocols on Leader-Based Consensus Communication" has been awarded with the Best Student Paper Award at the 6th ACM International Symposium on Blockchain and Secure Critical Infrastructure 2024.

In our work we investigate the performance and robustness impact of network transport protocols, secure channels and their configuration onto leader-based consensus. We experimentally quantify the impact of four transport protocols and two secure channel implementations on a HotStuff deployment. Our results show, that delays of a single processing layer often impact all layers above, and typical optimizations such as command batching or pipelining act as amplifiers. We demonstrate that tuning of the transport protocol building block opens a novel optimization space to a class of leader-based consensus algorithm deployments.

NetSec Guest Lecture: Cyber Security Assessments in Practice

30.01.2024

Abstract

At universities, cyber security is often viewed solely from the perspective of the attackers and defenders. In their guest lecture "Cyber Security Assessments in Practice", Nico Fechtner and Merten Nagel from usd AG shed light on a new perspective: They outline how compliance with legal and regulatory requirements in terms of cyber security is essential for a large number of companies. The presentation will look at the different motivations for and types of security analyses. In particular, security audits and penetration tests and the role of network security will be discussed in more detail and highlighted using practical examples.

WueWoWas'23: Best Workshop Contribution Award

30.06.2023

Best Contribution Award at WueWoWas 2023

Our publication "Never Miss Twice - Add-On-Miss Table Updates in Software Data Planes" has been awarded as the one Best Workshop Contribution at the KuVS Fachgespräch - Würzburg Workshop on Modeling, Analysis and Simulation of Next-Generation Communication Networks 2023 (WueWoWas’23).

In our work, we investigated the potential and performance of state insertions in P4 programmable data planes. Together with our previous work on updatable table entries, add-on-miss insertions enable powerful state-heavy applications with high performance directly in the data plane. The idea of add-on-miss insertions is brought up by the upcoming P4 Portable NIC Architecture targeting P4 applications running on the end hosts. We showed that the overhead of add-on-miss insertions in software targets is small, and therefore the approach is suited to run at line rate.

TMA'23: Best Paper Award

29.06.2023

Best Paper Award at TMA 2023

Our publication "Target Acquired? Evaluating Target Generation Algorithms for IPv6" has been awarded with the Best Paper Award at the Network Traffic Measurement and Analysis Conference (TMA 2023).

The publication is a collaboration with Oliver Gasser from the Max Planck Institute for Informatics.

In our work we investigated biases in the IPv6 Hitlist Service , a service maintained by our chair, which offers active IPv6 addresses to Internet researchers. This service is used to run measurements in the IPv6 address space and can also function as input for Target Generation Algorithms (TGAs). We found that being aware of and filtering a bias towards certain address categories can reduce unnecessary scan overhead and limit the bias in the addresses generated by TGAs.

Abstract

The DeFi ecosystem has experienced rapid growth, reaching over $253 billion in total value locked in just four years. However, this growth has been accompanied by numerous attacks resulting in a loss of at least $3.24 billion. This talk will introduce a systematic approach for evaluating and comparing DeFi attacks. Using data from academic papers, audit reports, and real-world incidents, we will identify gaps between academia and the practitioners' community. We will also examine potential defenses and their effectiveness. We will provide specific use cases showcasing how dynamic and advanced current attackers are. By understanding the challenges and potential solutions in DeFi, we aim to help strengthen its security and resilience.

Abstract

The design and development of TLS 1.3 was different from previous versions of the Transport Layer Security protocol (TLS). Community consensus led to it enforcing the latest generation of cryptography and making fundamental changes to the protocol flow. Prominent industry engaged at an unprecedented level, making TLS 1.3 the best-tested version ever to be deployed. TLS 1.3 is also the first TLS version to be developed in the age of pervasive mobile devices.

We track the rollout of TLS 1.3 since nearly its conception. We use longitudinal, active scans to measure the increasing deployment over more than 275m domains (including more than fifty ccTLDs), paying special attention to the role that big hosting and frontend providers play. We characterize the evolution of both deployment and use for both draft versions and the final RFC version, including an analysis of connection errors. We show which industries lead in the deployment of TLS 1.3, and we characterize the very different deployment in a variety of countries. We use passive monitoring at two positions on the globe to understand the initial testing phase and the degree to which users profit from the new protocol and its new features. Finally, we exploit data from a widely deployed measurement app in the Android ecosystem to analyze the use of TLS 1.3 in mobile applications.

Abstract

RouteNet is a novel network model based on Graph Neural Network (GNN) that can understand the complex relationship between topology, routing, and input traffic to produce accurate estimates of the per-source/destination per-packet delay distribution and loss. RouteNet leverages the ability of GNNs to learn and model graph-structured information and as a result, the model can generalize over arbitrary topologies, routing schemes and traffic intensity. In the evaluation,the RouteNet can predict accurately the delay distribution (mean delay and jitter) and loss even in topologies, routing and traffic unseen in the training.

Abstract

The scale and geographic dispersion of the Internet of Things (IoT) will surpass the size of the current day Internet in, at least, 3 orders of magnitude. The IoT will be the largest and most widely distributed system ever, with a multitude of connected sensors and actuators. The current Internet already has some serious, unresolved security problems. Adding physical world autonomous connections brings even more concerns about attacks and their consequences to people and goods. The SureThing project (http://surething-project.eu) is addressing an IoT security need: creating and validating location certificates. The project’s goal is to allow for constrained devices, needed in the provisioning of IoT services, to obtain proof of their location or to request proof of location to other devices. The certificates issued using the SureThing framework will contain location data, obtained and verified using: WiFi and Bluetooth fingerprinting, and ambience sensing. The SureThing framework will allow developers to choose between faster location proofs and more reliable proofs, which will be digitally signed and kept in a ledger. The witness models – providing a validation role for other devices at the same location – will play an important role, particularly when only limited cryptographic mechanisms are available.

Abstract

This talk covers two recent works in computing analytical functions over encrypted data. I will start with the traditional range search problem and show how to encrypt data, such that it can be efficiently searched and stored, but is provably secure against attacks by a snap-shot attackers. The problem entails a definition of securely encrypting a datastructure. Our approach can withstand all recent attacks on property-preservingly encrypted databases. In the second part of the talk I will talk about the problem of computing rank functions over the blockchain. This can be used to implement sealed-bid auctions over the blockchain. Our approach is secure against malicious adversaries and requires only 3 to 4 blocks to compute. We combine a number of techniques in an usual way to achieve this trade-off.

Abstract

Network Functions Virtualization (NFV) is among the latest network revolutions, bringing flexibility and avoiding network ossification. While NFV provides a flexible way of implementing network functions on commodity hardware, an all-software NFV implementation may present a performance gap with respect to hardware-based solutions. In the last decade numerous software acceleration techniques have appeared to bring high-speed capabilities to software network frameworks, thus trying to reduce the distance w.r.t. pure hardware solutions. Batching is one example of such techniques, consisting in processing packets in groups as opposed to individually, which is required at high-speed to minimize the framework overhead, reduce interrupt pressure, and leverage instruction-level cache hits. Whereas several system implementations have been proposed and experimentally benchmarked, the scientific community has so far only to a limited extent attempted to model the system dynamics of modern NFV routers exploiting batching acceleration. We fill this gap by proposing a simple generic model for such batching-based mechanisms, which allows a very detailed prediction of highly relevant performance indicators. These include the distribution of the processed batch size as well as queue size, which can be used to identify loss-less operational regimes or quantify the packet loss probability in high-load scenarios. In this talk I will present our experimental campaign for performance evaluation using a state-of-the-art NFV router, namely VPP. Then I will introduce our model for a generic NFV router. We contrast the model prediction with experimental results gathered in our testbed, showing that the model not only correctly captures system performance under simple conditions, but also in more realistic scenarios in which traffic is processed by a mixture of functions. rials will be discussed.

Abstract

The interconnection of heterogeneous devices in IoT is today performed via multiple IP-based messaging protocols which have been developed to assist a faster delivery of information over IP networks. These protocols, which perform well under restrained scenarios, require interoperability support (from/to the network as well as towards services) to scale well. Yet, today there is no standardized nor unified ICT model, capable of sustaining not only millions of heterogeneous devices, as well as: bi-directional communication towards people and devices.

In parallel, the Internet research community is exploiting novel networking paradigms, such as Information Centric Networking (ICN). ICN has, by design, a few networking architecture features (such as integrated security and the support for N to M communications) which seem to be better suited for large-scale, dense and mobile IoT environments, where bi-directional communication is required.

This talk provides an overview on the evolution of IoT communications and environments. It explains the requirements that need to be met when handling data transmission, be it in industrial IoT or personal IoT. The talk also provides a debate on the applicability of ICN to IoT; advantages and limitations, as well as interoperability towards today's environments.

Abstract

Underwater Acoustic Sensor Networks are used for the exploration of natural undersea resources, collection of oceanographic data, pollution monitoring, offshore exploration, disaster prevention, assisted navigation and tactical surveillance. Utilizing acoustic communications, sensor nodes gather and send data to sink nodes. Employing radio communications, the sinks forward the data to other surface located nodes or satellites. The Internet type of communication protocols work solely for sink nodes with classical wireless access. Specific protocols are required for submerged node communications.

In this talk, I will address protocol design for long range underwater/under ice acoustic communications. In the present state of scientific and technical progress, long range underwater communications are more likely to be achievable at low frequency and narrow bandwidth. We concentrate on low frequency mobile acoustic communications in the 300 Hz to 3 kHz range. Because of the narrow half-power bandwidth at low frequency and long distance, solely extremely low data rates are possible. At low data rates, the Doppler effect is also a difficult problem. My research draws on the science of extremely weak signal communications that can deal with channels with 250 dB attenuation or more. I will focus on the design of a data link layer protocol, which includes framing and high redundancy Forward Error Correction. The complexity is in the receiver. Algebraic and probabilistic decoding techniques are combined to determine what is most likely the content of a message. Performance results obtained through simulation and sea trials will be discussed.

Abstract

This talk presents solutions and open challenges on the corner stones of the Internet of Things (IoT): discovery, interoperability and composition. While discovery of suitable IoT devices is the initial step for interaction, various technologies (e.g. via networks or directories) exist. This talk presents generic discovery patterns useful for facilitating IoT usage. Once discovered, the interface of the IoT device needs to be understood. The broad heterogeniety of these interfaces has created a further gap of interoperability. We present a generic approach that utilizes semantic models to integrate IoT devices and platforms. Finally, once devices are interoperably accessible, their composition is crucial to facilitate re-usage and higher value creation. An approach is presented that allows the definition of IoT choreographies, their instantiation as applications, and automated re-configuration at runtime. The intention of this talk is to discuss the presented solution as well as challenges identified from an industry perspective.

PAM'18: Best Paper Award

27.03.2018

Best Paper Award at PAM 2018

The publication "In Log We Trust: Revealing Poor Security Practices with Certificate Transparency Logs and Internet Measurements" has been awarded with the Best Paper Award at the Passive and Active Measurement Conference (PAM'18). The publication is the result of an international collaboration with Maciej Korczynski (Grenoble Alps University and Delft University of Technology) and Ralph Holz (University of Sydney).

The publication evaluates the security of certificate in Certificate Transparency (CT) logs. The team downloads 600 million certificate entries from 30 different CT logs and evaluates their compliance to the industry's Baseline Requirements. The Baseline Requirements define standards for HTTPS certificates and issuing processes, such as minimum key lengths or maximum duration of certificates. Additionally, the authors perform active HTTPS measurements and compare CT logs to actual deployment spanning from 2009 to 2017. Moreover, the team analyzes inclusion of non-HTTPS certificates and CT logs and provides a CT-extended IPv6 hitlist for public download.

Abstract

As a society we have come to rely upon our mobile phones for myriad daily tasks. It is striking how little insight we, as mobile users and researchers, have into the operation and performance of our devices and network, into how (or whether) mobile apps protect the information we entrust to them, and with whom they share it. The research community (including the speaker) have energetically used a variety of approaches to gain empirical understanding of the mobile device/network ecosystem; however, these techniques have had to make trade-offs that affect either the scale, scope or granularity of measurements.

This talk describes how we leverage ideas from this prior work to design and develop the Lumen Privacy Monitor. The talk will demonstrate its utility to researchers and average users alike by providing case studies on mobile traffic characterization, identification of privacy risks inflicted by mobile apps, and perform network performance measurements.

Abstract

We start with discussing the opportunities of using machine learning for network and cloud engineering and operation. We then focus on the specific problem of KPI estimation and present an approach that is based based upon statistical learning, whereby the behavior of a system is learned from observations. Following this approach, we collect device statistics from servers and switches on a testbed and use regression techniques to predict client-side service metrics for a video service and a key-value store. One surprising finding is that these service metrics can be predicted quite accurately using network device statistics alone.

Abstract

Covert channels conceal the information transfer between communication partners by hiding it in an existing unsuspicious data exchange. In TCP/IP traffic there are many possibilities to hide information in header fields or packet timing. Such techniques can be used by sophisticated malware for clandestine data exfiltration or to establish hidden command and control structures. The detection of covert communication is very challenging if the hidden data replicates statistical properties of classical TCP/IP communication.

In this talk a set of methods, the DAT (Descriptive Analytics of Traffic) detectors, for detecting covert channels in TCP/IP traffic are introduced. The detectors are based on lightweight statistical analysis methods and provide a collection of technique to assess the probability of covert communication in a given traffic trace. The DAT detectors are also used in the TU Wien network steganography lab as part of the Network Security Advanced class. The lab material (exercises, data, grading) is made available to other lecturers in the area of network security and data analysis.

Abstract

Over the last six years, blockchains have developed into a 'mainstream' technology that entire industry sectors are talking about. The latest generation even supports smart contracts - programs that are executed by all participants and that may govern everything from simple transactions to the setup of organisations. Taking a closer look, however, we find that there is very little deployment beyond the two most prominent examples, Bitcoin and Ethereum. In this talk, we are going to look at some of the reasons: the problem of dependability and abortion of transactions, which is crucial for enterprises; the influence of the underlying network structure on transaction execution; and the problem of exploitable smart contracts. Correspondingly, we discuss some research directions that could prove fruitful in a number of systems, blockchains or beyond.

Abstract

State-of-the-art wireless communication already operates close to Shannon capacity and one of the most promising options to further increase data rates is to increase the communication bandwidth. Very high bandwidth channels are only available in the extremely high frequency part of the radio spectrum, the millimeter wave band (mm-wave). Upcoming communication technologies, such as IEEE 802.11ad, are already starting to exploit this part of the radio spectrum to achieve data rates of several GBit/s. However, communication at such high frequencies also suffers from high attenuation and signal absorption, often restricting communication to line-of-sight (LOS) scenarios and requiring the use of highly directional antennas. This in turn requires a radical rethinking of wireless network design. On the one hand side, such channels experience little interference, allowing for a high degree of spatial reuse and potentially simpler MAC and interference management mechanisms. On the other hand, such an environment is extremely dynamic and channels may appear and disappear over very short time intervals, in particular for mobile devices. This talk will highlight some of the challenges of and possible approaches for networking in the mm-wave band.

Abstract

As the Internet becomes increasingly important to all aspects of society, the consequences of disruption are increasingly severe. Thus it is critical to increase the resilience and survivability of the future networks in general, and the Internet in particular. We define resilience as the ability of the network to provide desired service even when the network is challenged by attacks, large-scale disasters and other failures. Resilience subsumes the disciplines of survivability, fault-tolerance, disruption-tolerance, traffic-tolerance, dependability, performability and security. This presentation will provide a brief introduction to the disciplines and challenges to network resilience and to our ResiliNets strategy for resilient network design. Then this presentation will describe the complex multilevel structure of the Internet topology, along with complex-systems analysis and heuristics to improve infrastructure resilience under cost constraints. Then this presentation will describe ongoing work in the design and analysis of a new composable, cross-layered resilient transport (ResTP) and geodiverse multipath routing protocol (GeoDivRP). These protocols are designed to are being developed to provide resilience and survivability in the face of targeted attacks and large-scale disasters to the network infrastructure.

Abstract

In this presentation, I will give an overview of recent advances in access and sensor networking in my group at ASU. In the area of access networks involving an optical fiber component, we have recently completed extensive studies on passive optical networks (PONs) as well as fiber-wireless (FiWi) access networks. Presently, we are examining the combination of high-speed PON access networks with slower-speed digital subscriber line (DSL) networks.

In the area of purely wireless access networks, we have analyzed the connection establishment in LTE-A networks. We found that for access systems with a long timeout and high barring probability, the numbers of user equipment (UE) nodes participating in random access contention in successive slots tend to Poisson process, irrespective of the arrival process (e.g., even for Markov Modulated Poisson Process arrivals).

In the area of sensor networks, we are working on developing a complete video sensor network solution ranging from the sensor node platform to the application layer streaming protocol. I will briefly outline a novel Wireless Sensor Node Platform (WSNP) approach to Dynamic Adaptive Streaming over HTTP (DASH).

Abstract

Self-organizing networks have emerged as a powerful paradigm for providing network services. Unlike traditional infrastructure-based networks, self-organizing networks are formed and operated in a fully distributed manner, and do not rely on centralized mechanisms for network formation, management, or operation. Compared to conventional networks, self-organizing networks are better suited to adapt to changes of network topology, traffic mix, and service requirements. This talk will make a case that self-organizing networks are suitable to dynamically adapt network services offered to applications. We present our recent efforts on developing mechanism to deploy customizable data delivery services. In our approach, a data delivery service is expressed in terms of an XML specification, which defines a finite-state machine for the service. Network nodes dynamically load a service specification and instantiate finite-state machines on-demand without the need to update the protocol implementation. An evaluation of these mechanisms in the HyperCast overlay middleware, sheds light on the performance tradeoffs of the approach.

Abstract

Network virtualization allows flexibility to configure virtual networks in a dynamic manner. In such a setting, to provide resilient services to virtual networks, we consider the situation where the substrate network provider wants to have standby virtual routers ready to serve the virtual networks in the event of a failure. Such a failure can affect one or more virtual routers in multiple virtual networks. The goal of our work is to make the optimal selection of standby virtual routers so that virtual networks can be dynamically reconfigured back to their original topologies after a failure. We present an optimization formulation and a heuristic for this problem. By considering a number of factors, we present numerical studies to show how the optimal selection is affected, and the results showed that the proposed heuristic's performance was close to the optimization model when there are sufficient standby virtual routers for each virtual networks and the substrate nodes have capability to support multiple standby virtual routers to be in service concurrently. We also report on an experimental study with a wide-area virtual network platform.

Abstract

Many recent high-profile security incidents have been categorized as "Advanced Persistent Threats" (APT). Their characteristic features include exploitation of previously unknown vulnerabilities and sophisticated social engineering carefully tailored to a specific recipient. To mitigate the growing risk of APT attacks arising from the economic and political motivation, novel detection methodology must be developed to complement the traditional signature-based techniques. In this talk, I will review the key features of APT and discuss the technical challenges arising in their detection. In particular, I will focus on methods for retrospective identification of 0-day attacks and evasion-resistant detection of malicious PDF documents commonly used for delivery of APT attacks. As an outlook, I will discuss potential architectures for security products which should provide adequate protection against APT.

Dimitri Papadimtriou "Analytical methods in system analysis"

18.09.2014

18.9.2014, 2:00 pm, FMI 03.05.033 (MI-Building, Campus Garching), this talk will be held in English Abstract: Predictive simulations provide insight into the physics that drive complex systems enabling identification of key mechanisms and allows for rigorous and robust optimization/design. However, predictive simulation requires careful assessment of all sources of numerical errors (discretization, resolution, etc.) and uncertainty (sampling, model parameters and equations, etc.) in particular, when aleatory (inherent to the variability present in system and its surroundings) and irreducible. Uncertainty propagation methods quantifies uncertainties in system output from all sources of input uncertainty by means of computational model (forward uncertainty propagation), determines which uncertainties contribute the most to output uncertainties (sensitivity analysis) and characterizes uncertainty. In turn, uncertainty quantification assists in model prediction (interpolation, extrapolation, etc.) and thus decision making. In this context, validation (process of determining the degree to which a model is an accurate representation of the real world for) of computational models for establishing confidence in model predictions plays a fundamental role. While predictive methods are mostly based on sampling, this talk investigates the use of analytical methods (such as reliability methods) to compute the probability of failure of structural systems.

22.7.2014, 2:00 pm, FMI 00.12.019 (MI-Building, Campus Garching), this talk will be held in English Abstract: The current Internet design is not capable of supporting communications in environments characterized by very long delays and frequent network partitions. To allow devices to communicate in such environments, delay-tolerant networking solutions have been proposed by exploiting opportunistic message forwarding, with limited expectations of end-to-end connectivity and node resources. However, such proposals present two major drawbacks: first, they ignore the impact that human behavior has on the dynamics of the network; and second, they focus on low density scenarios. This talk presents a study about the impact that human behavior has on opportunistic forwarding showing: i) that performance can be improved by taking the dynamics of the network into account; and ii) to show that delay-tolerant networking can also be used to reduce communication costs in networks with high density by considering the users' behavior.

Abstract: Stylometry is a form of authorship attribution that relies on the linguistic information found in documents. This paper focuses on the cross-domain case where the known and suspect documents differ in what setting they were created in. These domains include Twitter feeds, blog entries, Reddit comments, and emails. We determine that state-of-the-art methods in stylometry do not perform as well in cross-domain situations as they do in in-domain situations and propose a method that increases the accuracy in the cross-domain setting. We are able to improve the accuracy of cross-domain stylometry to as high as 80%. Being able to identify authors across domains facilitates linking identities across the Internet making this a key security and privacy concern; users can take other measures to ensure their anonymity, but due to their unique writing style, they may not be as anonymous as they believe.

Abstract:

This session consists of three talks of 30 minutes each. The first talk, by Barry Wellman, has the topic: “Triple revolution: the intersection of social network analysis, the far-flung personalized internet, and the mobile revolution”. The second speaker, David Clark, will talk about “Evaluating Network Architectures”. Finally, Marcelo Thompson will give a presentation entitled “The (Moral) Responsibility of Internet Intermediaries”.

Bio Berry Wellman: Professor Barry Wellman studies networks: community, communication, computer, and social. His research examines virtual community, the virtual workplace, social support, community, kinship, friendship, and social network theory and methods. Based at the University of Toronto, he directs NetLab at the Faculty of Information, is the former S.D. Clark Professor at the Department of Sociology, and is a member of the Cities Centre and the Knowledge Media Design Institute. Wellman is the co-author of the prize-winning Networked: The New Social Operating System (with Lee Rainie, Director of the Pew Internet and American Life Project) published by MIT Press in Spring 2012. The book analyzes the social nature of networked individualism, growing out of the Social Network Revolution, the Internet Revolution, and the Mobile Revolution.

Bio David Clark: David Clark is a Senior Research Scientist at the MIT Computer Science and Artificial Intelligence Laboratory, where he has worked since receiving his Ph.D. there in 1973.

HybridNN: An accurate and scalable network location service based on the inframetric model

Abstract: Locating servers that have shortest interactive delay towards an Internet host provides an important service for large-scale latency sensitive networked applications, such as VoIP, online network games, or interactive network services on the cloud. Existing algorithms assume that the delay space is a metric space, which implies that the delay between two nodes is symmetric and the triangle inequality holds. In practice, the delay space is not metric, which lowers the accuracy of metric-based algorithms. We develop a new scheme whose theoretical foundation is based on the inframetric model, which has weaker assumptions than the metric model. We prove that the location requests can be completed efficiently if the delay space exhibits modest inframetric dimensions, which we can confirm empirically. Finally, we propose HybridNN (Hybrid N earest Service N ode Location) that finds the closest service node accurately thanks to the inframetric model and scalably by combining delay predictions with direct probes to a pruned set of neighbors. Simulation results show that HybridNN locates in nearly all cases the true nearest service nodes. Experiments on PlanetLab show that with modest query overhead and maintenance traffic HybridNN can provide accurate nearest service nodes that are close to optimal. This is joint work with Y. Fu and Y. Wang from National University of Defense Technology, Hunan province, 410073, China Bio: Ernst Biersack studied computer science at the Technische Universität München and at the University of North Carolina at Chapel Hill. He received the Dipl. Infom. (M.S.) and Dr. rer. nat.

Talk by Richard Stallman| Jul 11 18:00 | MW 2001

11.07.2012

Richard Stallman will be visiting us in Munich in mid-July.On July 11th at 18:00 he will give a public talk in English on "Copyright vs. Community" at the Technische Universität München.

The talk will be in the "Rudolf-Diesel" Hörsal "MW 2001" on the Campus Garching. The talk is open to the public and attendance is free. Registration is not required, but you can register with the Free Software Foundation for notifications about related activities here.

Summary

Copyright developed in the age of the printing press, and was designed to fit with the system of centralized copying imposed by the printing press. But the copyright system does not fit well with computer networks, and only draconian punishments can enforce it. The global corporations that profit from copyright are lobbying for draconian punishments, and to increase their copyright powers, while suppressing public access to technology.

This applies to scientific publishing too: scholarly articles must permit redistribution and remix for the good of science. We must strip the journal publishers of the power to prevent this.

If we seriously hope for copyright to serve its only legitimate purpose --to promote progress, for the benefit of the public-- then we must make changes in the other direction.

About the Speaker

Richard Stallman launched the free software movement in 1983 and started the development of the GNU operating system in 1984. GNU is free software: everyone has the freedom to copy it and redistribute it, with or without changes. The GNU/Linux system, basically the GNU operating system with Linux added, is used on tens of millions of computers today. Stallman has received the ACM Grace Hopper Award, a MacArthur Foundation fellowship, the Electronic Frontier Foundation's Pioneer Award, and the the Takeda Award for Social/Economic Betterment, as well as several honorary doctorates.

Internet Censorship and the Tor network Speaker: Jacob Applebaum University of Washington Date: Tuesday, 7th of February 2012, 6:30pm Location: FMI Interimshörsaal 2(Campus Garching, Boltzmannstr. 5) This talk will be held in English

Abstract: Internet censorship as done by governments is a very real problem faced by many people all over the planet. This is a lecture about who censors and why they censor. Specifically, the talk covers how governments and corporations attempt to censor access to the Tor anonymisation network and to what lengths governments have gone to stop Tor as a way to communicate safely with the outside world. The talk will cover some real world examples that the Tor network has faced and continues to face and it will discuss deployed solutions and provide a forum for discussion of possible future developments. Speaker's bio: Jacob Appelbaum is a computer security researcher currently employed by the University of Washington. He is also a core member of the Tor project. He is a founding member of the hacklab Noisebridge in San Francisco where he indulges his interests in magnetics, cryptography and consensus based governance. He was a driving force in the team behind the creation of the Cold Boot Attacks; winning both the Pwnie for Most Innovative Research award and the Usenix Security best student paper award in 2008.

Gastvortrag von Prof. Wolfinger am 17.06.10 um 17:15

17.06.2010

Es spricht: Prof. Bernd Wolfinger Universität Hamburg

Termin: Donnerstag, den 17.06.10 um 17:15 Ort: Raum MI Hörsaal 2 (MI-Gebäude, Campus Garching) Thema: Performance Engineering and Traffic Engineering for Multimedia Applications in the Internet and in Mobile Networks

Abstract: Performance Engineering of computer and communication networks, among others, comprises practices, methods and tools which can be applied in order to design, implement and operate networks and their applications in such a way that given performance and Quality-of-Service (QoS) requirements are fulfilled. ‘Traffic Engineering’ for networks – in its broader sense – comprises formal specification, measurement, modelling, characterization and manipulation (routing, traffic shaping, etc) as well as the generating of traffic loads in networks. Performance engineering and traffic engineering are particularly relevant in the context of the Internet and of mobile networks, more so, if those networks are used for real-time communications. The talk summarizes the long-term experiences in traffic and performance engineering within the Telecommunications and Computer Networks Division at Hamburg University. In particular, emphasis will be given to our recent research results related to measurement-based load characterization of audio and video streams, to formal load specification and analytical modelling of load transformations (stochastic load transformations as they are currently studied within the DFG project LUPUS) as well as to the elaboration of two powerful performance and traffic engineering tools: a distributed load generator for multimedia traffic in service-integrated networks and a network emulator to reflect the packet delay and loss behaviour of, possibly interconnected, computer and communication networks. A case study will be presented to illustrate the broad applicability of our load generator (UniLoG) and network emulator (NetEmu) prototypes. These experiments will also show that valid QoS-related studies for distributed real-time applications can be flexibly supported by a combined usage of both, the network emulator and the load generator tool. With our approach the strict separation between network-oriented and application-oriented performance studies is no longer required – an important step towards a realistic QoS evaluation from an end-user’s point of view. Bio: Prof. Dr. Bernd E. Wolfinger has been with the Computer Science Department of Hamburg University since 1981, where he is presently heading the Telecommunications and Computer Networks (TKRN) Subdivision. Dr. Wolfinger has obtained degrees from Université Claude-Bernard, Lyon/F. (Maîtrise, ‘74), University of Karlsruhe/D (Diploma, Mathematics ‘75; Ph.D., Comp. Sc. ’79). He has spent long-term sabbaticals at IBM Research / Yorktown, N.Y. (‘85), Internat. Computer Science Institute / Berkeley, Ca. (’91,’96), as well as at Université P. et M. Curie, LIP 6, Paris (’01, ‘06). Professor Wolfinger is active in Networking research since 1975, has been responsible for numerous conference organizations and has served on a large variety of TPCs. He has been editor of books and special issues of journals; he has published more than 100 papers in areas such as High-speed & Wireless Networks and Real-time (audio/video) Communications as well as in Modeling (Simulation & Queueing Networks) , Measurement, Traffic Engineering, Performance & Reliability Evaluation, QoS Management and eLearning.

Due to the high cost pressure put on mobile network operators, the efficient Management of Mobile Networks (Deployment, Operation, Maintenance) has gained a lot of importance and visibility. Particularly automation solutions ("Self Organizing Networks") are considered to be a key building block for LTE networks by operators and network equipment vendors. Based on an overview on mobile networks and their management, a concrete example (self-configuration of basestations) will be discussed, showing the opportunities and challenges in this area. Additionally the presentation gives some insights into the product development process (idea -> concept -> product-feature) and the tasks of a research group within a large network equipment manufacturer.

Bio: Henning Sanneck is Research Manager at Nokia Siemens Networks in Munich where he is leading projects on Self-Organizing Networks for LTE.

TUM Informatik I8-Sonderkolloquium mit James Sterbenz am 05.10.09

05.10.2009

E I N L A D U N G

zu einem TUM Informatik I8-Sonderkolloquium: Es spricht: Prof. James P.G. Sterbenz, Ph.D. The University of Kansas, U.S.A. http://www.ittc.ku.edu/~jpgs Termin: Montag, den 05.10.09, 14 Uhr Ort: Raum MI Besprechungsraum Informatik8 03.05.033 (MI-Gebäude, Campus Garching, 3. OG, Finger 5) Thema: Resilience, Survivability, and Heterogeneity in the Postmodern Internet James P.G. Sterbenz Abstract Society increasingly relies on computer networks in general, and the Internet in particular. Consumers rely on networks for access to information and services, personal finance, and for communication with others. The Internet has become indispensable to the routine operation of businesses and to the global economy. The military depends on network centric operations and warfare. Governments depend on networks for their daily operation, service delivery, and response to natural disaster and terrorist attacks. Furthermore, the Internet is being used in ways not anticipated by its designers and evolution of the protocols, in particular: TCP, IP, BGP, DNS, and HTTP. Emerging application paradigms and mashups coupled with usage scenarios that are increasingly disconnected and mobile challenge the current architecture. This has been recognised by research and development initiatives including NSF FIND (Future Internet Design), GENI (Global Environments for Network Innovation), and EU FIRE (Future Internet Research and Experimentation). This presentation will focus on two key aspects of the future Internet: resilience and heterogeneity. Resilience: The consequences to disruption of the Internet are increasingly severe, and threaten the lives of individuals, the financial health of business, and the economic stability and security of nations and the world. With the increasing importance of the Internet, so follows it's attractiveness as a target from bad guys: recreational and professional crackers, terrorists, and from information warfare. The EU FIRE ResumeNet project is exploring resilience and survivability as critical properties of the future Internet architecture. Heterogeneity: New applications and usage scenarios stress the Internet architecture that has evolved assuming a stable wired infrastructure. While the current hourglass waist provided by IP, DNS, and BGP has served the Internet well, the demand for heterogeneity stresses the least-common-denominator of the waist. The NSF FIND Postmodern Internet project (PoMo) is exploring heterogeneity as a first-class citizen in the Postmodern Internet, in which a new internetworking protocol serves as the glue for heterogeneous realms with explicit support for trust and policy boundaries. The Great Plains Environment for Network Innovation (GpENI) is constructing part of the GENI infrastructure, which will in part be used as a platform to test and evaluate ResumeNet and PoMo architecture. Additionally, research in two domain-specific realms will be described. Highly Dynamic Airborne Networking Highly dynamic mobile wireless networks present unique challenges to end-to-end communication, particularly caused by the time varying connectivity of high-velocity nodes combined with the unreliability of the wireless communication channel. Addressing these challenges requires the design of new protocols and mechanisms specific to this environment. Our research explores the tradeoffs in the location of functionality such as error control and location management for high-velocity multihop airborne-sensor networks and presents cross-layer optimizations between the MAC, link, network, and transport layers to enable a domain specific network architecture, which provides high reliability for telemetry applications. We have designed new transport, network, and routing protocols for this environment: TCP-friendly AeroTP, IP-compatible AeroNP, and AeroRP, which show significant performance improvement over the traditional TCP/IP/MANET protocol stack. Weather Disruption-Tolerant Millimeter-Wave Mesh Networking Millimeter-wave networks have the potential to supplement fiber in providing high-speed Internet access, as well as backhaul for emerging mobile 3G and 4G services. However, due to the high frequency of operation (70-90 GHz), such networks are highly susceptible to attenuation from rain. A resilient mesh topology with cross-layering between the physical and network layer has the potential to self-optimise under the presence of unstable links. Our research investigates mechanisms to overcome the disruptive effects of rain storms on network connectivity and service reliability. We propose two novel domain-specific predictive routing algorithms: P-WARP that uses real-time radar data to dynamically reroute traffic in advance of link failures, as well as a modified link-state algorithm XL-OSPF that uses cross-layering to instantaneously react to link failures. Simulations evaluate the effectiveness of the proposed algorithms based on data from real storms in the Midwest US. Bio Dr. James P.G. Sterbenz is Associate Professor of Electrical Engineering & Computer Science and on staff at the Information & Telecommunication Technology Center at the University of Kansas, and is a Visiting Professor of Computing in InfoLab 21 at Lancaster University in the UK. He has previously held senior staff and research management positions at BBN Technologies, GTE Laboratories, and IBM Research. His research interests include resilient, survivable, and disruption tolerant networking, future Internet architectures, active and programmable networks, and high-speed networking and components. He is currently in the NSF-funded FIND and GENI programs, and the EU-funded FIRE ResumeNet project. He received a doctorate in computer science from Washington University in 1991. He has been program chair for IEEE GBN and HotI, IFIP IWSOS, PfHSN, and IWAN, and is on the editorial board of IEEE Network. He is principal author of the book High-Speed Networking: A Systematic Approach to High-Bandwidth Low-Latency Communication.

Gastvortrag von Prof. Dr. Jörn Altmann am 20.07. um 13:00

20.07.2009

Es spricht: Prof. Dr. Jörn Altmann Seoul National University, South Korea http://www.my-groups.de/altmann/?page_id=19 Termin: Montag, den 20.07.09, 13 Uhr Ort: Raum MI Seminarraum 03.07.023 (MI-Gebäude, Campus Garching, 3. OG, Finger 7) Thema: Capacity Planning for Cloud Computing Resources Due to the few options of computing resources currently available in the existing market, capacity planning is simple to perform. However, envisioning a market for commercial computing resources as part of a Cloud computing environment, capacity planning will become more complex due to the availability of many different resource types at variable prices. In this situation, the user will require support for handling the capacity planning process and for making use of Cloud computing in a cost-effective manner. The support could come from an online, stand-alone Capacity Planning Service, enabling companies to outsource their capacity planning task. This talk describes the Cloud Capacity Planning Service and demonstrates the workings of the service. This work on capacity planning has been partly performed within the EC-funded project GridEcon, Grid Economics and Business Models. GridEcon introduced the design and implementation of the GridEcon Marketplace, which not only provides the market mechanism for trading computing resources on a pay-per-use basis but also provides an environment for value-added support services for using the Cloud computing market more efficiently. The Marketplace and market mechanism were validated by using the GridEcon Platform, which is a service-oriented platform for composing market scenarios.

Promotionsvortrag von Michael Kleis

30.03.2009

Im Rahmen seines Promotionsverfahrens hält Herr Dipl.-Math. Michael Kleis am Montag, 30.03.2009, 11.00 Uhr, im Raum 01.07.023, MI-Gebäude, Boltzmannstr. 3 in Garching einen Vortrag zum Thema "CSP, Cooperative Service Provisioning using Peer-to-Peer Principles" Betreuer: Prof. Georg Carle

Zusammenfassung

Current challenges for Internet service provisioning include incorporating an increasing number of wireless and wired network technologies, a variety of heterogeneous end user terminals and the requirements of delay and bandwidth sensitive multimedia services. There are two main obstacles for flexible media provisioning on top of today's Internet. First the end-to-end networking paradigm which is based on a service and data unaware transport, and secondly a lack of high level communication abstractions. To address the first point this thesis proposes a methodology to integrate the Network Provider into the process of service provisioning. The proposed cooperative service provisioning (CSP) demands an interaction between Service Provider, Network Provider and Client. CSP can be applied to Provider as well as Peer-to-Peer scenarios. To address the second point, the thesis adopts a Service Overlay approach. It is studied how the principle of Distributed Hash Tables (DHTs) can be extended to realise a distributed control plane for a decentral and reactive creation of Service Overlays. As a prerequisite, a methodology to reduce Service Overlay related routing problems to search problems is developed. With regard to the required Quality of Service (QoS) measurements, the thesis focuses on scalable and time efficient estimation techniques. As a result, two new delay prediction schemes have been developed which improve estimation accuracy when compared to the state of the art. Furthermore, a novel approach to bandwidth estimation is investigated. It combines methods from landmark based delay estimation with a transformation step and has favourable estimation accuracy.

Talk 1: On Security in Ad Hoc Networks Abstract: Access control concerns in MANETs are very serious and considered as a crucial challenge for operators who prospects to employ unrivaled capabilities of such networks for different applications. We propose a novel hierarchical distributed AAA architecture for proactive link state routing protocols notably OLSR . This proposal contains a lightweight and secure design of an overlay authentication and authorization paradigm for mobile nodes as well as a reliable accounting system to enable operators to charge nodes based on their connection duration time. We also suggest a hierarchical distributed AAA (Authentication, Authorization, and Accounting) server architecture with resource and location aware election mechanism. Moreover, this proposal mitigates the OLSR security issues noticeably and eventually defines a node priority-based quality of service. Dr. Hakima CHAOUCHI is associate professor at the Telecommunication Institute in France. She received her PhD in 2004 in telecommunications and networking. Previously, she was a research fellow at Paris VI University, and also joined the Centre for Telecommunication Research of London (CTR) as a research associate. Her research work is related to wireless and mobile networks and Security. She was involved in European and French research projects. She is currently coordinating one of the first French projects on Internet of Things SUN (Situated and Ubiquitous Networks). She is the co-editor of the “Security in Wireless and mobile networks” book (ISTE 2009) and the “emerging wireless technologies, IEEE standard” book (Hermes 2008) and the last one coming end of 2009 on “Internet of Things”. She recently co-organized the first and the second workshop in mobile and wireless network security (MWNS 2008, MWNS 2009) and is a member of several technical program committees. Talk 2: Wife: Wireless Indoor Positioning Fingerprint based Evaluation Abstract: Location awareness of a user or device has always been considered as a key element for enhancing network performance and improving user experience by enabling innovative location-based services. In this paper, we present WIFE (Wireless Indoor positioning based on Finger- print Evaluation), a user-based location determination system which is based on the received Signal Strength (SS) received from the surrounding Access Points (APs) inside a building. We focus on a WiFi environment for its low cost and ease of deployment and study Fingerprint-based deterministic techniques for their simplicity and reduced processing time and resource requirements. We first address the inherent impairments of an indoor environment and then describe our proposed methodology for mitigating them. Apostolia Papapostolou is a second year Ph.D. candidate at the Telecom Institute in South of Paris in France. She obtained her bachelor degree from the department of Computer and Communications Engineering at the University of Thessaly (Greece) in 2006 and her Master of Science degree from the department of Mobile and Personal Communications at King's College, University of London in 2007. Her research interests include wireless and mobile networks. Her current focus is on positioning, mobility management techniques and location based services.

TUM Informatik-Sonderkolloquium mit Stephan Heckmüller am 10.12.08 um 13 Uhr in MI 01.06.011

10.12.2008

Gastvortrag von Herrn Dipl-Inf. Stephan Heckmüller (TKRN, Universitiät Hamburg) zum Thema "Lasttransformation in Rechnernetzen und ihre Invertierung".

Zeit: Mittwoch, 10.12.08, 13:00 Uhr Ort: Raum MI 01.06.011

Heutige Rechnernetze werden von einer Vielzahl von netzbasierten Anwendungen genutzt, die Verkehr mit teilweise stark unterschiedlichen Eigenschaften induzieren. Diese Eigenschaften werden darüber hinaus innerhalb des Netzes durch eine Vielzahl von Verarbeitungsvorgängen modifiziert. Um trotz der Komplexität des resultierenden, heterogenen Verkehrs-Mixes realistische Leistungsbewertungen vornehmen zu können, ist eine valide Charakterisierung und Modellierung des Verkehrs unverzichtbar. Im Rahmen des Vortrags werden insbesondere die Einflüsse der Verarbeitungsvorgänge innerhalb des typischen Protokollstapels heutiger Rechnernetze betrachtet. Die hier erfolgenden Modifikationen der Lasteigenschaften bezeichnen wir als Lasttransformationen. Die Berücksichtigung dieser Transformationen erlaubt die Modellierung von Lasten an tieferen Schnittstellen aufbauend auf der ursprünglichen Lastcharakterisierung und den Eigenschaften des spezifischen Transformationsvorgangs. Der Vortrag befasst sich zunächst mit der Modellierung solcher Lasttransformationen als Abbildungen auf Batch Markovian Arrival Processes (BMAPs). Neben der Vorstellung des grundsätzlichen Konzeptes wird auf die bisher betrachteten Lasttransformationen eingegangen. Insbesondere wird hierbei eine Transformation, welche den Einfluss eines Token-Bucket-Moduls modelliert, näher betrachtet. Mit Hilfe einer Fallstudie wird die erfreulich hohe Genauigkeit der entwickelten Transformationen aufgezeigt. Neben der Vorhersage von Lasteigenschaften nach der Transformation ist die Invertierung von Lasttransformationen ebenfalls von Interesse. Dies gilt insbesondere dann, wenn Lasten nur an tieferliegenden Schnittstellen innerhalb des Protokollstapels beobachtbar sind und Eigenschaften an höheren Schnittstellen rekonstruiert werden sollen. Potentielle Anwendungsgebiete umfassen Anwendungsklassifikation, Angriffserkennung und Lastmodellierung für nicht beobachtbare Schnittstellen. Es werden erste Ergebnisse bezüglich der Rekonstruktion von Längeneigenschaften und von zeitlichem Verhalten präsentiert.
