摘要
The trust mechanism for peer-to-peer (P2P) network had been proposed as a promising methodology to handle the complex security problems. The basic idea of the trust mechanism for P2P network is to let parties rate each other after the completion of a transaction, and use the aggregated ratings of a given party to derive a trust score, which can assist other parties in deciding whether or not to transact with that party in the future. In this paper, firstly the concepts of trust mechanism existing in the P2P network are summarized and presented. Secondly the relationship between trust mechanism and network security is analyzed and the framework of trust system is discussed. Thirdly the latest techniques on trust model and trust inference method are summarized respectively. Finally several typical trust model systems and their mathematical inference methods are described in details. The current problems of trust mechanism for P2P network and research trends in this area are also discussed.
