提出了一种基于P2P环境的信任管理模型,基于实体的行为经验构建实体间的相对信任关系,并采用改进的分布式存储机制应用于全局信誉值的管理。使得网络中各节点在维护管理全局信任关系的工作中合理地分担计算负载和存储负载,提高了信任管理系统的整体性能。
In P2P environment, all kinds of open, dynamic and changeful applications post more demands for network security and reliability. Based on evaluation among peers, this paper introduce improved DHT to establish trust model to ensure the availability of trust information and resolve high maintenance costs caused by the join and exit of nodes, and thus enhance the performance of the system.
