TrustP2PNet: P2P Social Network with Admission Control Model based on Trust

This paper proposed a Trust based Admission Control Model (TACM) for P2P network, and implemented a P2P social network system TrustP2PNet based on TACM. The TrustP2PNet is composed of application layer proxies with P2P structure. Additionally, a admission control model based on recommendations from trustable friend in social networks is proposed to prevent malicious peers fromthe TrustP2PNet. Both the simulation results and the practical application of TACM in the system TrustP2Pnet show that, with our model, it can not only effectively protect the system from malicious peers but alsopossessvery good scalability.
