摘　　要：提出了一种基于节点推荐可信度的信任模型,通过对推荐节点的服务质量和推荐质量进行区分,实现节点推荐行为的量化评估,最大程度地降低虚假反馈对提供服务节点的诋毁或吹捧,有效保证服务节点全局信任值的真实可靠性。仿真分析表明,该模型可以有效抑制信任模型中不诚实反馈行为的危害性。To solve the problem in peer-to-peer network, a trust model is presented with node＇s recommend credibility. Through differentiating the quality of service and recommendation provided by node, quantization and evaluation about node recommend behavior is realized, discredit or flatter about service nodes lead by fake feedback is reduced in degree. These measure availably ensure service node＇s reliability of global trust value. Simulation analyses show that, this model can restrain harm of dishonestly feedback more effectively.
