对等网络信任度分布式存储的研究

利用结构化对等网络的优点,由网络中的部分节点组成结构化的叠加网络来储存节点信任度的多个拷贝,并提出了节点信任度的加密报告机制和简单的报告消息验证方法,抵抗恶意节点篡改自己或同伙的推荐的企图.这种方法能够在进行全局信任度计算时,将离开系统的节点的评价纳入考虑的范围,并保证在需要使用信任度值时,确定的有限步内找到信任度文件.

THE DISTRIBUTED TRUST STORAGE IN PEER-TO-PEER NETWORK

Based on the advantages of structured peer-to-peer network,a part of nodes are organized into a structured peer-to-peer network to store multiple copies of trust files of nodes in the system.To prevent malicious nodes from tempering with its own trust value or its peers,a scheme in which the transaction feedbacks can be reported in encryption and the reporting messages can be verified simply is proposed.In this way,the further global trust computation can include the experiences of the nodes who left the system and the trust files can be searched out within definite steps.
