New P2P trust model based on group
一种基于群组的P2P网络信任管理模型*

To solve the problem of a variety of malicious behaviors in P2P networks, this paper proposed a novel trust model based on group. Through grouping strategy, computed the global trust degree of peer by using direct trust degree, group trust degree, trust degree between groups and mutiple control factors. Simulation results show that the proposed model has fairly good inhibitory action to malicious acts, and can evidently enhance successful transaction ratio of system and efficiently help peers establish trust relationships in P2P networks.
