| 摘 要： | 针对现有对等网络系统中的声誉模型不能很好地处理虚假反馈和合谋的问题,结合公平思想,提出了一种新的基于双ratings的声誉模型.采用两个度量来评价节点:服务信任和回馈信任.服务信任表示服务节点提供服务的可靠性;回馈信任表示评价节点评价的可靠性.该模型根据节点历史交易情况,通过比较评价节点的评价值以及比较评价节点的回馈信任,识别虚假反馈和合谋,并给出了具体量化的服务信任和回馈信任数学表达形式.实验结果表明了模型的可行性和算法的有效性.

| Abstract: | The reputation model in the P2P(peer-to-peer) system can't deal with false feedback and conspiracy well.Aimed at these questions,a novel reputation model based on dual ratings is proposed,combining with the fair ideas.Two metrics,namely,the trust of service and the trust of feedback,are used to evaluate the node.The trust of service could show the service reliability of service nodes.The trust of feedback could show the evaluation reliability of evaluation nodes.The model put forward generally applicable an... |
