To effectively solve the security problem in P2P electronic commerce trading, this paper analyses the existing trust model and proposes an improved trust model. The trading sum, trading evaluation, trading time and trading time are introduced into the direct trust computing to prevent against malicious cheat of nodes. The punishment factor suppresses the cheat behaviour of nodes and effectively prevents the malicious nodes from cheating at certain frequently. When recommendations from other nodes are combined, the weighted averaging method and trust of the recommendation nodes are used to effectively prevent malicious nodes from providing malicious recommendation. The simulation experiment indicates that this mode can effectively beat the malicious nodes, protect the honest nodes, enhance security of the P2P electronic commerce nodes, and reduce the trading risks.
