| 摘 要： | 为了解决P2P网络开放性和自治性带来的信任问题，提出一种基于Gossip算法的信任模型。该模型在估计节点的信任关系时引入时间退化因子，使用基于网络拓扑结构的Gossip算法传递消息、聚集信誉。模拟实验结果表明，该模型能更有效地评估节点间的信任关系，提高查询效率，减少网络拥塞。

| Abstract: | In order to resolve the trust problem in open and autonomous P2P network,a trust model based on Gossip algorithm is proposed in which peers can autonomously deal with the information and identify trust belief with aging factor in P2P network. Simulation experimental result shows that the model can identify the peers' trust with lower overhead and higher efficiency. |
