Trust Management Model Research In The Peer-to-Peer Network Environment Based On Reputation

P2P networks is a new computing architecture that are emerging in recent years, which are widely used in many areas, P2P networks is an open and dynamic environment in nature, so in P2P networks, the development process, resulting in a lot of issues need to be studied and resolved. The most important thing is security issues, we to trust management with trust models and reputation systems have further studied, and will introduce the trust relationship to P2P network, learn from real social life, interpersonal learning, for each node in the P2P by evaluating to establish confidence value, thus establishing a P2P network environment of trust management model. The quality of Resources in P2P networks is difficult to be assured, some malicious nodes in the characteristics of the use of P2P network itself spread viruses and Trojan horses or quality of unreliable files. Therefore, the study security issues of P2P networks, we must solve the P2P network nodes in the issue of credibility.In the P2P environment, resources are widely distributed in the network entities, direct interaction between the numbers are sparse, how P2P networks each peer to establish a stable relationship of trust between, has become a research hotspot in P2P networks. Through elaborate on the existing P2P trust model based on the proposed management model based on reputation, trust management group and recommended trust management model are two important parts of this article. Through our interactive new trust management model for repeated experiments in the model, The proportion of malicious nodes in different situations, Our trust model of the nodes in a higher rate of success of interactive. experiments show that the node can be more effective attack against malicious nodes in order to improve the P2P network to attain the purpose of let it reliability and security.
