The Comprehensive Trust Model in P2P Based on Improved EigenTrust Algorithm

According to the problems existing in the EigenTrust algorithm that the considered factors when local trust are little and the trust values are lack of global superiority, We proposed a new FSEM-EigenTrust algorithm based on Fuzzy Synthetic Evaluation Model. In this method, Each trading node was evaluated individually by several factors and these single values were aggregated into weighted sum, the synthetic evaluation value, which is regarded as the local trust value. Through the contrast experiment on EigenTrust, it shows that FSEM-Trust can improved the success rate of trading and enhance the ability of resisting attacks from the malicious nodes in p2p.
