摘要： 分析一种基于数据分析的攻击方法，根据被动监听网络所获得的信息，推断无线网络节点之间的通信关系。仿真实验结果表明，该方法在不同场景下能够达到85%~90%的准确率，在大量掩护消息存在的情况下，性能良好。提出一种更为完善的掩护消息方法，强化了现有无线匿名路由协议的功能。

Abstract: This paper analyzes a new attack for estimating anonymous routing paths, purely based on passive traffic monitoring, and applies the attack to AnonDSR. The promising results on simulation data are presented, with 85%~90% accuracy in different scenarios, even within an environment containing cover traffic, or noise. In addition, it designs a new smart cover traffic scheme which helps enhance anonymity in existing protocols.

Key words: wireless anonymous routing protocol, AnonDSR, EM algorithm
