项目摘要

SING: Toward a Theoretical Foundation ofAnonymous Wireless NetworkingAbstractAs wireless networking increasingly dominates our means of communication, the need for privacy and security has gained prominence. Wireless networks, owing to the unprotected communication medium, are vulnerable to unauthorized access of networking information. For example, by merely observing transmission times of packets, a passive eavesdropper can decipher source-destination pairs and paths of data flow in a network. Unauthorized retrieval of such information, known as traffic analysis, is a violation of user privacy. It also provides crucial information for the jamming of network traffic and launching of a denial-of-service attack.This research aims to establish an analytical framework for achieving anonymity in wireless networks. The key objectives are to establish a theoretical framework upon which provably anonymous and secure protocols for multiple access communication and anonymous networking can be developed and analyzed. Drawing ideas of anonymous mixing from Internet privacy, timing channel analysis from information theory, and intrusion detection from statistical inference of point processes, countermeasures against passive and active means of compromising anonymity are investigated. Parallel to the well known rate-secrecy trade-off in point-to-point communications, fundamental tradeoffs between anonymity and network performance metrics, such as throughput and delay, are investigated. Scheduling and routing protocols are developed to prevent unauthorized release of networking information to passive and active adversaries.

Sing：走向匿名无线网络的理论基础摘要随着无线网络日益主导我们的通信手段，对隐私和安全的需求已经变得突出。无线网络由于通信介质不受保护，容易受到网络信息的未经授权的访问。例如，通过仅仅观察分组的传输时间，被动窃听者可以解密网络中的数据流的源-目的地对和路径。未经授权检索此类信息（称为流量分析）是对用户隐私的侵犯。它还提供了重要的信息，网络流量的干扰和拒绝服务攻击的发动。本研究旨在建立一个分析框架，实现匿名在无线网络中。主要目标是建立一个理论框架，在此基础上，可证明匿名和安全的多址通信和匿名网络协议可以开发和分析。借鉴互联网隐私的匿名混合，从信息论的时间通道分析，和入侵检测的统计推断点过程的思想，被动和主动的手段，损害匿名性的对策进行了研究。平行于众所周知的速率保密权衡点到点通信，匿名性和网络性能指标，如吞吐量和延迟之间的基本权衡，进行了研究。调度和路由协议的开发是为了防止未经授权的网络信息发布到被动和主动的对手。
