Abstract
Peer-to-peer (P2P) E-commerce systems are more and more popular in recent years with opportunities and threats both existing. A lot of malicious nodes threaten the system’s security via cheating, selfish and attacking or else. Trust mechanisms can help estimating the trustworthiness. This paper presents a distributed trust model named P2PETrust (peer-to-peer E-commerce trust model) based on social networks’ principles. A transaction history vector with multi dimensions is designed to describe the history before the distributed storage structure. In order to compute the trust, three sub trust models are defined in P2PETrust, which are local model, global model and correlation model. The local trust model is the base trust mechanism to compute history between two nodes after defining the nonlinear time factor, transaction amount factor, frequency factor and success rate for the history while the global one is based on local model to calculate a node’s whole transaction histories with some global factors defined. On the basis of these jobs, a correlation trust model is presented by calculating nodes’ correlative similarity multiplied with global trust degree. We present a simulation environment to validate the proposed trust model and report the set of initial experiments, showing the feasibility and benefit of our approach. Key words: Peer-to-peer E-commerce, trust model, P2P security, social network, network security.

Summary
Peer-to-Peer (P2P) overlay network (Touch, 2001), which is self-organized and distributed, can make full use of the edge system entities in internet-scale to construct largescale cooperating and resource sharing environments. The model has the following innovative features: It designs a transaction history vector and its distributed storage structure for P2P trust computing. This distributed method do not need additional topology but conforming to specific P2P topology which uses the P2PTrust. The transaction amount is based on value-amount which means the real value of the transaction amount calculated by the success rate, and the time factor is not simple linear to express the time’s importance.
