Research of Trust Model in P2P File-Sharing System

In this paper, a trust model based on real-time behavior detection scheme was proposed in P2P file-sharing system. It solved the problems in computing trust value only by past performances and choosing service nodes improperly. It took real-time behavior detection both in trust computing and service choosing, improving the accuracy of the trust value and the rationality in service nodes choosing. The experimental results proved the advantage of this scheme.
