摘要: 借助于社会人工学中信任的概念,把P2P网络中节点交互的历史信息作为样本信息,结合先验信息对节点的未来行为做出推断,并根据节点之间信任关系不同,区分了直接信任和推荐信任,并分别给出了两种信任关系基于贝叶斯理论的计算方法。最后与L.Mui等人的模型作了比较。

Abstract: In P2P network,history interaction information of nodes takes as sample information in this trust model.Combining prior information of nodes makes inference the node further behavior.According to the difference of the node’s trust relationship,distinguish direct trust and recommended trust,and respectively give two kinds of calculation method.Finally it has made the comparison with L.Mui’s model.

Key words: trust model, P2P network, Bayesian theory, network security
