| 摘 要： | 信任管理是P2P系统保证信息安全的重要前提和基础.分布式信任机制被广泛应用于开放系统信任模型的设计,然而,缺乏有效的信任机制来保证参与分布式计算的节点本身的安全性.在仔细分析了P2P系统的信任问题后,为保证节点的安全性提出一种高度自治的P2P环境下的信任管理模型.该模型通过加强节点的自治能力,使每一个节点可以自主地建立一张与它交易的节点的信任表,并通过主观推理方法得到其他间接节点的信任值,提高了网络本身的自适应性,为信任管理研究提供了一种新思路.

| Abstract: | Trust management is fundamental for information security in peer to peer network.There are sev- eral models which applied distributed method to construct trust between peers,but there is no way to guaran- tee security of the peer's behavior.In this paper,the nature of the trust is considered,and the paper present a highly self-governing trust model for peer to peer network.This model enhances the ability of self-govern- ment of peers,for the security of the peers each peer holds a local trust table for those who have exchanged information with it directly,and can determine the other indirect peers trust degree by subjective reasoning method.This improves the open net-work self-adaptability,and gives a new and valuable way for studying trust management in P2P network. |
