A trust evaluation approach of P2P nodes based on trust computing

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 under the trusted environment are proposed. An algorithm for computing the trust values is put forward based on the trust relationship among hosts, nodes and pseudonyms. The security analyses prove that the approach can ensure anonymous of host in trusted environments and defend P2P network against the Pseudo spoofing and ID stealth attacks.
