The lack of stable node identity is the central problem in peer-to-peer network security. Based on the general characteristics of trust between social networking and P2P network, a trust model and an approach of evaluation trust in P2P network are proposed. An algorithm for computing the trust values is put forward based on the relationship among hosts, nodes and pseudonyms. The analyzes prove that the approach can ensure anonymity of host and defend P2P network against the Pseudo spoofing and ID stealth attacks.
