摘要：

基于社会规则和非结构化P2P网络的拓扑特性，提出一个用于非结构化P2P网络的信任管理方案，给出评价信息的分布式存储方案和信任度的计算、更新、搜索方法。该方法的计算复杂度和报文通信量较低。仿真实验结果表明，该信任机制能有效抵制非结构化网络中恶意节点的攻击。

Abstract:

A trust model based on social rules and the topology characteristic of unstructured P2P network is proposed in this paper. A distributed storage mechanism of evaluation information is designed. The calculating, updating and searching methods of reputation information are given. The computation complexity and communication cost of this algorithm are low. Experimental results show that the proposed trust mechanism can resist the attack of malicious peers effectively.

Key words: unstructured P2P network, trust mechanism, topology characteristic
