摘要： 针对P2P匿名网络存在的网络稳定性和匿名安全性的隐患问题，在非结构化P2P网络拓扑结构中引入动态形成的索引节点和基于信誉度的IP前缀节点选择算法，通过采用多通道、动态中继组等策略实现一个新的基于P2P的匿名通信系统——TreeMix系统。通过模拟实验和对相关数据的分析，证明该系统在保持可扩展性的同时，具有较强的抵抗节点失效的能力，较好地解决了匿名通信效率问题。

Abstract: In order to solve the problem on channel stability and anonymous security existing in P2P based anonymous communication network, this paper presents a new P2P based anonymous communication system called TreeMix. Strategies including dynamic index peers, reputation and IP prefix based peer selection, multi-channel, dynamic relay group are introduced into unstructured P2P network to build the TreeMix System. This system is proved more resistant to peer failure without loss of extensibility and can solve the communication efficient problem better by simulation experiment and data analysis.

Key words: anonymous communication, dynamic relay group, multi-channel
