摘要
信任模型是目前提高Peer-to-Peer网络系统安全性的一个重要方法。在分析各类信任模型[1]的特点和节点行为特征的基础上,提出了一种基于层次域的全局信任模型,采用邻近原则和信任度[2]划分节点域,并在此基础上加入了奖惩机制,具有较好的信任收敛度和对恶意行为的防范效果。
Trust model is an important mechanism to improve the security of peer-to-peer network system. A novel P2P global trust model based on hierarchical-domain is proposed. Locality-awareness and trust-threshold are used to distinguish peer domain. Performance analysis demonstrates that it has good performance and can well protect system from different malicious behaviors.
