摘要
针对数据传输时所需通信分析暴露通信者身份及相互关系的问题,采用混淆网络和洋葱路由来掩饰其真实通信,通过建立匿名路径来防止通信中的流分析,但所有路由器需要通过交换路由信息了解整个网络的拓扑结构.提出一种分布式匿名路由协议.该协议不需要任何节点收集和存储网络拓扑信息.模拟结果表明该协议具有较好的可扩展性.
Traffic analysis reveals valuable information about end users and their relationships. MIX networks and onion routing are examples of technologies that mask real traffic and establish anonymous path against traffic analysis. To establish these anonymous paths, all touters require a global view of the network topology by exchanging routing information. A distributed anonymous routing protocol （DARP） is developed. It does not require any node to gather and store information about the network topology. Simulation results indicate the average processing time increases linearly with the increase of the number of nodes.
