| 摘 要： | P2P网络的匿名性和动态性带来了许多安全问题,传统的信任管理模型并不能很好地适应P2P网络环境,动态信任模型是新的研究热点。本文在对现有P2P环境中的信任机制进行分析的基础上,通过研究消费节点对服务节点的信任,针对节点间的信息交换活动提出了一种改进的信用评估模型,评估服务提供者在信息交换过程中的信用度变化过程;并引入风险机制,分析了P2P网络中节点间进行信息交换的风险。实验证明,该模型能有效地抗信用炒作和抗周期性欺骗。

| Abstract: | The anonymity and dynamic of the P2P network bring many security problems. The traditional trust management models can not satisfy the P2P environment commendably,and the dynamic trust mechanism is a new and hot topic of security research for these new distributed applications.Based on the analysis of the existing trust models for the P2P networks,through the research of the trust of consumptive nodes on the service nodes,this paper proposes an improved credit evaluation model for the information exchange b... |
