基于信任介绍的Ｐ２Ｐ安全研究

934190497

　摘要：本文在分析研究传统信任模型的基础上，结合近两年最热门的网络架构方式，建立了一种新的基于p2p网络的信任介绍机制。这个机制利用了节点过去在网络中的历史经验，建立了节点之间的信任关系，更加有效的去解决网络中信任关系，而其算法比较简洁，比一些具有复杂算法的信任模型更适合在现实网络中的应用。该机制能够增强网络可用性，具有结构简单、可靠性强的优点。

　　abstract:this paper proposed a novel recommend trust mechanism based upon peer-to-peer network, one of the most popular and rapidly developed networking structures. this mechanism makes fully use of the past experience of node itself and builds reputation relation between interactional nodes，so it is effectively to solve the problem of lack trust in p2p network. further more, this algorithm is compactly and more useful when apply it in real network, and this mechanism can enhance p2p's usability and make it more sampler and trustable.
