摘要
Abstract
Effective trust mechanism for P2P networks needs to be constructed to isolate malicious peers and guarantee successful completion of transactions between peers against multiple network attacks. Considering the characteristics of behaviors of peers and the importance of negative evaluation, trust mechanism based on negative evaluation dissemination is proposed. Once a transaction is evaluated negatively, the information of the negative evaluation will be disseminated to related peers which have completed transactions in a certain period of time with the upload peer. The impact of negative evaluation on the reputation of peer is enhanced. The reputation value of the peer after computed twice can reflect the actual reputation level and the trends of transactions of the peer. Simulations are given and the results show that the trust mechanism can guarantee the success rate of transaction completion and defend against attacks effectively.关键词
