Abstract—Nowadays, Peer-to-Peer network represents a large portion of internet traffic, and becomes fundamental data sources. Because of lacking the security mechanism from third-party, P2P network will face some severe trust problems such as service faking and resource abusing by some malicious peers. The conventional security measures can not be used to cater for this demand, whereas the scenario based on reputation has widely been accepted. Through studying the present reputation, the paper presents a cluster-based reputation model (CBRM). The model is consisted by reputation mechanism and cluster. In the model, we take the reputation mechanism for realizing the security transaction; and the network topology structure of CBRM adopts the cluster, so efficiency of reputation management is noticeably raised. In order to improve security, reduce the network traffic brought by management of reputation, and enhance stability of cluster, when we select reputation, the average historical online time, and the network bandwidth as the elementary components of the comprehensive performance of node. Simulation results showed that the proposed model improved the security, reduced the network traffic, and enhanced stability of cluster.
