| Abstract | In order to implement both the efficiency and security in the Peer-to-Peer (P2P) network, we design a trusted small world overlay P2P network with the role based and reputation based access control policies, denoted as SW-R2P. The SW-R2P system integrates the small world topology with zero knowledge identification and Bayesian trust model. The zero knowledge identification is utilized to securely cluster all the peers into several groups without transferring any related information. The peer groups are then linked together to construct a trusted small world network based on the probabilities calculated by the Bayesian trust model. The simulation experiments demonstrate that the SW-R2P system achieves the performance with increased success rate in the resources lookup, strengthened robustness under the overwhelming traffic loadings, reduced reputation errors caused by the malicious peers and enhanced peer satisfaction rate for different trust metrics. In conclusion, the SW-R2P system collectively exploits the advantages of small world, zero knowledge identification and Bayesian trust model, therefore implementing a scalable, secure and efficient P2P network. |
