Integrated trust model for peer-to-peer network

A secure and effective trust model is a key technology of the P2P system’s great efficiency and stabilization.An integrated peer-to-peer trust model is proposed in this paper,which comes from construction approach of trust relations in the social network,in which,a peer’s trust value is calculated according to two aspects.Some security mechanisms,such as unsymmetrical encryption,are introduced into this model.Analysis and simulation results testify that this model can deal with some security problems,such as impostor attack and slander,is provided with rather security.
