摘　　要：针对P2P匿名网络存在的稳定性与安全性的问题,结合匿名通道建立时选择性能与表现良好的节点的需求,提出构建一种基于P2P匿名环境的信誉度模型。模型在信誉计算时引入通信持续时间作为参数,给出了动态调整节点信誉以及利用信任度计算推荐信誉度的数学方法。实验结果表明,该模型能有效地区分节点间的服务和评价行为,利用该信誉度模型选择节点构建匿名通道保证了P2P匿名通道的稳定性。Considering that there exists some stability and security problems in P2P anonymous networks, a reputation model is proposed based on P2P anonymous environment to select peers with high performance and good behavior while establishing anonymous channels. Communication duration is introduced as parameter when calculating the reputation value and the mathematical method for dynamic adjusting peer＇s reputation value and calculating peer＇s recommendation reputation value using trust value is given. We demonstrate this model can distinguish service and evaluation between peers effectively and improve the anonymous channel stability through simulation experiments and analysis of the results.
