Low-Cost Traffic Analysis Of Tor

by Steven J. Murdoch, George Danezis - In Proceedings of the 2005 IEEE Symposium on Security and Privacy. IEEE CS , 2005
"... Tor is the second generation Onion Router, supporting the anonymous transport of TCP streams over the Internet. Its low latency makes it very suitable for common tasks, such as web browsing, but insecure against trafficanalysis attacks by a global passive adversary. We present new traffic-analysis t ..."

Analysis, Modeling and Generation of Self-Similar VBR Video Traffic

by Mark Garrett, Walter Willinger , 1994
"... We present a detailed statistical analysis of a 2-hour long empirical sample of VBR video. The sample was obtained by applying a simple intraframe video compression code to an action movie. The main findings of our analysis are (1) the tail behavior of the marginal bandwidth distribution can be accu ..."

On the Self-similar Nature of Ethernet Traffic (Extended Version)

by Will E. Leland, Murad S. Taqqu, Walter Willinger, Daniel V. Wilson , 1994
"... We demonstrate that Ethernet LAN traffic is statistically self-similar, that none of the commonly used traffic models is able to capture this fractal-like behavior, that such behavior has serious implications for the design, control, and analysis of high-speed, cell-based networks, and that aggrega ..."

Self-Similarity Through High-Variability: Statistical Analysis of Ethernet LAN Traffic at the Source Level

by Walter Willinger, Murad S. Taqqu, Robert Sherman, Daniel V. Wilson - IEEE/ACM TRANSACTIONS ON NETWORKING , 1997
"... A number of recent empirical studies of traffic measurements from a variety of working packet networks have convincingly demonstrated that actual network traffic is self-similar or long-range dependent in nature (i.e., bursty over a wide range of time scales) -- in sharp contrast to commonly made tr ..."

Data Streams: Algorithms and Applications

by S. Muthukrishnan , 2005
"... In the data stream scenario, input arrives very rapidly and there is limited memory to store the input. Algorithms have to work with one or few passes over the data, space less than linear in the input size or time significantly less than the input size. In the past few years, a new theory has emerg ..."

emerged for reasoning about algorithms that work within these constraints on space, time, and number of passes. Some of the methods rely on metric embeddings, pseudo-random computations, sparse approximation theory and communication complexity. The applications for this scenario include IP network traffic

Fingerprinting websites using traffic analysis

by Andrew Hintz - Workshop on Privacy Enhancing Technologies , 2002
"... I present a traffic analysis based vulnerability in SafeWeb, an encrypting web proxy. This vulnerability allows someone monitoring the trac of a SafeWeb user to determine if the user is visiting certain websites. I also describe a successful implementation of the attack. Finally, I discuss methods ..."

Graph Wavelets for Spatial Traffic Analysis

by Mark Crovella, Eric Kolaczyk - IN IEEE INFOCOM , 2002
"... A number of problems in network operations and engineering call for new methods of traffic analysis. While most existing traffic analysis methods are fundamentally temporal, there is a clear need for the analysis of traffic across multiple network links --- that is, for spatial traffic analysis. ..."

Introducing Traffic Analysis

by George Danezis, Richard Clayton - Attacks, Defences and Public Policy Issues , 2007
"... In the Second World War, traffic analysis was used by the British at Bletchley Park to assess the size of Germany’s air-force, and Japanese traffic analysis countermeasures contributed to the surprise of their 1941 attack on Pearl Harbour. Nowadays, Google uses the incidence of links to assess the r ..."

Metrics for Traffic Analysis Prevention

by Richard E. Newman, Ira S. Moskowitz, Paul Syverson, Andrei Serjantov - in Proceedings of Privacy Enhancing Technologies Workshop (PET 2003 , 2003
"... This paper considers systems for Traffic Analysis Prevention (TAP) in a theoretical model. It considers TAP based on padding and rerouting of messages and describes the effects each has on the difference between the actual and the observed traffic matrix (TM). The paper introduces an entropy-based a ..."

Capacity of Ad Hoc Wireless Networks

by Jinyang Li, Charles Blake, Douglas S. J. De Couto, Hu Imm Lee, Robert Morris
"... Early simulation experience with wireless ad hoc networks suggests that their capacity can be surprisingly low, due to the requirement that nodes forward each others’ packets. The achievable capacity depends on network size, traffic patterns, and detailed local radio interactions. This paper examine ..."
