A Management Model of Security and Trust in P2P Base on Recommendation

A Management Model of Security and Trust in P2P base on recommendation is Designed. This model bases on a kind of network architecture as character of management authentication in deconcentration and self-organization. Then building SuperPeer by the way of self-adaption in order to divide P2P network into several small-scale logical networks, by this way to transfer the recommend trust barometer and also avoid the presence of network bottleneck. The nodes in P2P acquire overall trust barometer by SuperPeer, then calculate its final trust barometer. The most trust peer is responsible for the mission of calculating to ensure the quality of service. In this paper, the result of the experiment shows that our model of security effectively resolve the problem of trust barometer in P2P, and improve the success rate of the transaction, possessing a good application value.
