%X Trust plays an important role in determining who and how to interact in open and dynamic P2P network.To this end,a trust mechanism for unstructured P2P network was proposed in which peers evaluate the trust based on beta probability distribution and aggregate the reputation with Gossip algorithm.The experimental data shows that our way can autonomously deal with the biased information and identify trust belief with low overhead and better efficiency.
