TAP: a novel tunneling approach for anonymity in structured P2P systems
Yinan Zhu, Y. Charlie Hu · 2004
In this paper we present TAP, a novel Tunneling ap-proach for Anonymity in structured P2P systems. An im-portant feature of TAP is that anonymous tunnels are fault-tolerant to node failures. Relying on P2P routing infras-tructure 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 bal-ance 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. 1.
