A Reputation Evaluation Method in P2P Anonymous Environment

With some critical defects existing in a P2P anonymous network such as stability and security issues, we propose a novel approach called REM-P2PAE to evaluating the reputation based on P2P anonymous environment in the light of our research and analysis. These defects having long been neglected including the short on-line time of reputation model peers, the variations in dynamic situations of peers, and the malicious assessment are now considered in this paper. The method introduces communication duration as a parameter whenever evaluating the reputation value and gives the mathematical method for dynamic adjusting peer´s reputation value and evaluating peer´s recommendation reputation value using confidential value. We demonstrate that this research can distinguish service and evaluation behaviors between peers and the reputation evaluation method can enhance the stability of anonymous channel effectively through simulation experiments and analysis of the results.
