以信用为基础的P2P系统隐私保持机制

A Recommendation-based Peer-to-peer Trust Model

在P2P文件共享系统里利用节点和其友好节点之间的信任,采用友好节点作为代理来请求和获取文件,提出了一种以信任为基础的隐私保持机制.理论和实验分析表明,该机制有效地阻断了文件的源与其内容之间的联系,同时可以防止恶意行为对信任的攻击,能为用户提供更好的隐私保护.

We propose a scheme of privacy preservation-using friendly peers as proxies during date requesting and sending.This proposed scheme removes the immediate association between the identity of the participator and the accessed data.Meanwhile,it can prevent some malicious attrack and strengthen system security.In order to verify the effectiveness of our proposed scheme,experiments have been carried out.
