Abstract

We present TAP, a novel tunneling approach for anonymity in structured P2P systems. An important feature of TAP is that anonymous tunnels are fault-tolerant to node failures. Relying on P2P routing infrastructure and replication mechanism, the basic idea behind TAP is to decouple anonymous tunnels from "fixed" P2P nodes and form anonymous tunnels from dynamic tunnel hop nodes. The primary motivation of TAP is to strike a balance between functionality and anonymity in dynamic P2P networks. We have implemented the tunneling mechanism in Java on FreePastry 1.3. An analysis of its anonymity and performance was evaluated via detailed simulations.

TAP:结构化P2P系统中一种新颖的匿名隧道方法
我们提出了TAP,一种在结构化P2P系统中实现匿名的新型隧道方法。TAP的一个重要特性是匿名隧道对节点故障具有容错能力。基于P2P路由基础设施和复制机制,TAP的基本思想是将匿名隧道与“固定”P2P节点解耦,并从动态隧道跳节点形成匿名隧道。TAP的主要动机是在动态P2P网络中的功能性和匿名性之间取得平衡。我们已经在FreePastry 1.3上用Java实现了隧道机制。通过详细的仿真分析了其匿名性和性能。
