在交易评估机制中，信任度是根据个体交易的历史信息，由多重因素综合而成。这些因素在评估机制中均有作用和影响，但由于各个因素自身的特点，其作用和影响大小不一。本文由此提出了一种多重因素综合的 P2P网络信任评估模型，给出了新的信任评估计算方法和仿真实验。实验结果表明，该评估模型效果显著。本文提出的信任评估模型是属于对等信任模型，该模型适合P2P网络的特性。对于对等信任模型而言，其难点是如何建立起网络节点之间的信任关系，其优点是保持了P2P网络的特性。

In the transaction evaluation mechanism, trust is based on historical information of individual transactions, and composed of multiple factors into. There are effect and influence of these factors in the evaluation mechanism, but due to the characteristics of its own, its effect and influence are different sizes. This Paper proposes a model of multiple factors based on the trust evaluation for P2P network, gives a new calculation method of the trust evaluation, and the model’s simulation results. The experimental results show that, the evaluation model has significant effect. In Paper the trust evaluation model is a peer-to-peer trust model, and fit for the P2P network. For peer-to-peer trust model, it is difficult to establish a trust relationship between network nodes, and its advantages are maintained the characteristics of P2P network.
