摘　　要：在分析P2P电子商务特点的基础上,提出一种基于群的信任模型CPNM.与传统信任模型不同的是,节点的信任度主要由同群内的节点评估而不是用全体节点进行评估;在信任度量中,除交易总数和交易反馈两个常规参数外,还引入了交易规模参数.经模拟实验测试,CPNM可以降低网络负载,保证较高的网络性能,表现出良好的抗共谋攻击能力.By analyzing the properties of P2P E-commerce,a cluster-based ti＇ust model,CPNM,is proposed. Compared with the conventional trust model, several differences exist in this model. Firstly, the trust value of a node in CPNM is rated by other nodes in the same group,not all the nodes in the network. Secondly,in addition to the transaction numbers and transaction feedback, the transaction size is also introduced in the calculating of the trust value. The efficiency of our model is proved by simulation.
