P2P可信管理技术是模仿现实社会中的信任建立过程,根据用户之间过去发生的交易行为及其参与节点的反馈信息,对网络中的每个节点给出一个“可信程度”的评价,节点在请求服务时可以根据此评价来选择“可信”的服务提供者。介绍了P2P的网络结构、特点及存在的安全问题,讨论了P2P网络中的信任管理,分析总结了现有的信任管理模型的优缺点,并对今后的研究方向做出了展望。
P2P Trusted Management Technology is to simulate the process of trust establishment in the real world. According to the past transactions between users and the feedback information of their participating nodes, each node in the network is given a “credible degree” Evaluation, the node in the request of service can be based on the evaluation to select “trusted ” service provider. This paper introduces the P2P network structure, features and existing security issues. It discusses the trust management in P2P networks, analyzes and summarizes the advantages and disadvantages of the existing trust management models, and gives the prospect of future research directions.
