一种基于混沌数字指纹技术的P2P网络环境信任机制方案

A trust mechanism solution for P2P network environment base on digital fingerprint and chaos technology

由于P2P网络中存在大量欺诈行为、攻击和不可靠的服务,使服务质量无法得以较好的保证。文章介绍了p2p网络时间向量,然后利用混沌加密技术对时间向量构建数字序列,通过数字序列构成数字指纹来使通信双方建立信任;仿真实验表明:新模型较传统的模型能更有效的识别出具有复杂策略的节点,在抵御恶意节点的各种动态行为上有更好的性能。

A large number of frauds,attacks and unreliable services exist in P2P file-sharing network,which makes the service quality unable to reach better assurance.This paper introduces the p2p network time vector,and then use the vector of time chaotic encryption technology to build a sequence of numbers,And a sequence of digital fingerprint through digital communications at building confidence to make.Finally,Experiments show that this model call distinguish the malicious node with complex strategies effectively and performs better in dealing with various dynamic behaviors of peers.
