摘要:

在点对点(P2P)网络中,由于不存在可信中心,实体间的信任关系无法使用传统方式建立.针对这一问题,在已有研究的基础上,提出了一种新的P2P网络信任管理模型. 该模型基于模糊理论构建服务行为评价,可以根据用户的需求进行定制. 该模型通过将历史行为分组,并赋予不同的权值,提供了一种简捷有效的时间相关性算法. 该模型使用分布式存储的方法来处理推荐信息,降低了搜集推荐信息的消耗.

Abstract:

In peertopeer(P2P) networks, there are not trusted authorities, Trust relations between peers cannot be establish with traditional methods. A new trust model for P2P networks is described, in which trust relations between peers are set up upon reputations. Utilizing fuzzy theory, it can be customizable. Also utilizing time grouping, it presents a concrete but concise method to solve the time relativity problems. After storing the reputation information of each peer in its neighbors, it will reduce the network traffic and delay problems.

Key words: trust management, peer to peer networks, fuzzy theory, time relativity, reputation
