对等网络中不同信任模型的比较分析

在诸如文件共享等的Peer-to-Peer环境中,资源共享是用户自愿的行为,在这类系统中由于用户不必为自身的行为担负(法律)责任,因而节点间的信任关系就显得尤为重要。对几种信任模型进行比较,这些模型分别侧重于评估各个节点的服务质量和惩罚不信任的节点等不同侧面,经过比较分析,得出建立P2P信任模型需要考虑的几个方面。

Comparative Analysis of Trust Models for P2P Networks

For most peer-to-peer file shared environment,sharing is a volunteer action,and peers are not responsible for themselves' behaviors,so the trust relations between the pees are important.This paper compared several different trust models which respectively emphasized on evaluating the peers' QoS and punishing the distrust peers,so proposed the some problems needed to consider when construct a P2P trust model.
