Effectiveness of Traffic Camouflaging in Internet

Wei Zhao
Effectiveness of Traffic Camouflaging in Internet

Tuesday, April 29th
Amos Eaton 214 - 4:00 p.m. to 5:00 p.m.

Abstract:


For many Internet applications, the ability to protect the identity of participants and the characteristics of their communication in distributed applications is critical. For such applications, a number of traffic camouflaging systems have been developed over the past several years. The effectiveness of these systems relies greatly on (1) the protocol by which messages are (re-)routed among the participants and (2) the scheme by which links are padded. In this talk, we will discuss our discoveries on the effectiveness of these camouflaging methods. Our results contradict some of the methods that have been commonly used. For example, we find that using more agents in re-routing may not necessarily increase the probability that a sender can be identified. Furthermore, padding links with a constant-bit rate pattern may result in the worst probability; that an adversary can identify the underlying payload status. We will discuss how to develop optimal strategies for these traffic camouflaging systems.

Bio:

Wei Zhao is currently the Dean of the School of Science at Rensselaer Polytechnic Institute. Before he joined RPI in 2007, he was a Senior Associate Vice President for Research at Texas A&M University. Between 2005 and 2007, he also served as the Director for the Division of Computer and Network Systems in the National Science Foundation. He completed his undergraduate program in physics at Shaanxi Normal University, Xi'an, China, in 1977. He received his M.Sc. and Ph.D. degrees in Computer and Information Sciences at the University of Massachusetts at Amherst in 1983 and 1986, respectively. During his career, he has also been a faculty member at Amherst College, the University of Adelaide, and Texas A&M University. As an IEEE Fellow, Wei Zhao has made significant contributions in distributed computing, real-time systems, computer networks, and cyber space security. His research group has been recognized by receiving various awards and prizes, including the outstanding paper award from the IEEE International Conference on Distributed Computing Systems, the best paper award from the IEEE National Aerospace and Electronics Conference, an award on technology transfer from the Defense Advanced Research Program Agency, and the 2nd prize in the international ACM student research contest. Dr. Zhao is an inventor for two U.S. patents and has published over 250 papers in journals, conferences, and book chapters.
