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.

在过去的十年中，由于人们对通过互联网通信的隐私问题的担忧，匿名交流受到了越来越多的关注。尽管这些现有的匿名通信网络可以极大地帮助保护通信隐私，但这些网络，尤其是低延迟的匿名通信网络，容易受到许多流量分析攻击的影响。该项目的主要目的是研究匿名通信的新架构，以便打败流量分析攻击，即被动和主动分析攻击。该项目着重于通过网络编码来消除网络流量的统计结构信息来隐藏流量模式，而网络编码从未尝试过。与现有方法相比，新方法将能够隐藏交通模式，同时实现更高的带宽效率，并且在服务质量方面的降解较小。匿名网络的科学基础是通过了解和分析匿名级别，网络可用性以及所需的网络资源数量之间的复杂关系来建立的。如果成功的话，该项目将有助于刺激有关匿名方法的新研究。计算和通信设置的越来越普遍的性质，以及匿名网络的日益普及，保护各种互联网应用程序的沟通隐私和隐私非常重要。该项目还可以作为向少数族裔学生介绍学术研究活动的一种手段，并将额外的本科生和研究生带入网络安全和隐私领域的研究。
