Anonymous communication has received increasing attention in the past decade because of concerns on privacy issues of communication through the Internet. Although these existing anonymous communication networks can greatly help protect communication privacy, these networks, especially the low-latency anonymous communication networks, are vulnerable to a number of traffic analysis attacks.The main objective of this project is to study new architectures for anonymous communications in order to defeat traffic analysis attacks, both passive and active traffic analysis attacks. The project focuses on hiding traffic patterns by dissipating statistical structure information of network traffic through network coding, which has never been tried before. Compared to the existing approaches, the new approaches will be able to hide traffic patterns while achieving higher bandwidth efficiency and suffering less degradation in the quality of service. A scientific foundation for anonymity networks is to be established through an understanding and analysis of the complex relationship among the levels of anonymity, usability of the networks, and amount of network resources needed. The project, if successful, will help stimulate new researches on anonymization approaches.Given increasingly pervasive nature of computing and communication setting and increasing popularity of anonymity networks, protecting communication privacy and privacy of various Internet applications is of great societal importance. The project also serves as a means to introduce minority students to academic research activity and to bring additional undergraduate and graduate to research in the network security and privacy area.

匿名通信在过去的十年里受到越来越多的关注，因为通过互联网通信的隐私问题的关注。虽然这些现有的匿名通信网络可以极大地帮助保护通信隐私，这些网络，特别是低延迟的匿名通信网络，容易受到一些流量分析攻击，本项目的主要目标是研究新的匿名通信架构，以抵御流量分析攻击，包括被动和主动流量分析攻击。该项目的重点是通过网络编码耗散网络流量的统计结构信息来隐藏流量模式，这是以前从未尝试过的。与现有的方法相比，新的方法将能够隐藏流量模式，同时实现更高的带宽效率和遭受较少的服务质量下降。匿名网络的科学基础是通过对匿名性水平、网络可用性和所需网络资源量之间复杂关系的理解和分析来建立的。鉴于计算和通信环境的日益普及以及匿名网络的日益普及，保护通信隐私和各种互联网应用的隐私具有重大的社会意义。该项目还作为一种手段，介绍少数民族学生的学术研究活动，并使更多的本科生和研究生在网络安全和隐私领域的研究。
