Trust model based on recommended in P2P network environment
P2P网络环境下基于推荐的信任模型

The nodes in network are not only confined the trust relationship which established by trading directly, but also including the third party's recommended trust. This paper presented a trust model based on recommended in P2P environment. It used the proportion of success and failure in the trade total number as direct trust value, the model distinguish between transaction reputation and recommendation reputation definitely. Besides it introduced the credibility of the recommended node with offset factor to calculate, and had got the integrated trust value of target node by the directly trust of dynamic equilibrium node with the punishment factors and the risk factors, and recommended trust other nodes. Finally, it gare the simulation experiments. The experimental results show that the integrated trust value is more close to real value, and can resist threats such as slandered by malicious node, collaborative cheating and so on.
