摘要：In order to change the defect of traditional trust model, the research on trust model based on P2P network is proposed in this paper. It is based on the theoretical characteristic of P2P network and analyzes the trust mechanism and application model and set up a kind of new trust model. This kind of trust model is great helpful to improve the success rate of transaction and the trust model was designed. Finally, the simulation experiment is made. The results show that using P2P trust model can be more effectively inhibit and isolate the malicious nodes than the other and improving PZP network environment can make the network gets a benign development.
