摘要: 网络信誉系统是一个用于综合运算、记录并发布各个客户端以往行为表现的系统。在P2P开放网络资源共享系统中,网络信誉系统起到了两个重要的作用:向用户提供信息以决定对方是否可信,激励交易双方在交易中保持良好的表现以提高自身的信誉度。该文介绍了P2P开放网络与信誉管理系统的概念,分析了现有的信誉系统、模型及其算法。在此基础上设计了新的模型,该模型以信任链方式查询节点信誉度,提出把信誉度分层的方法,通过Java实现了该系统,展望了网络信誉系统的发展方向。

Abstract: Network reputation systems are the systems that record, aggregate and distribute information about the past behavior of peers in an application. In the P2P resource-shared system, reputation systems serve two primary purposes: helping peers decide whom should be trusted and providing incentives to peers to be well-behaved. This paper introduces the concept of P2P network and its reputation systems, and analyses the present reputation systems, their models and algorithms. Based on the above new reputation system model is designed, in which the peer’s reputation metric can be queried by trust links. Reputation metric delaminating is also presented and the reputation system has been implemented with Java. At last some prospect of reputation system is given.

Key words: P2P open network, reputation systems, trust links, distributed reputation systems, witness peers
