Research of P2P Security Based on Recommend Trust

This paper proposed a novel recommend trust mechanism based upon Peer-to-Peer network,one of the most popular and rapidly developed networking structures. This mechanism makes fully use of the past experience of node itself and builds reputation relation between interactional nodes,so it is effectively to solve the problem of lack trust in P2P network. Further more,this algorithm is compactly and more useful when apply it in real network,and this mechanism can enhance P2P's usability and make it more sampler and trustable.
