一种适合P2P系统的群信任模型

针对现有的信任模型对网络节点的约束力不足,本文提出一种群信任模型。该模型参考社会学的人际关系的群结构,把若干具有相同属性的节点组成一个群体,对于群内的节点不仅具有单个信任度属性,而且还有群的信任度属性。和其他模型相比较,该模型能够提高对网络节点的约束力,降低恶意攻击的频率和激励节点做出善意行为。

A Group Trust Model Suitable for P2P System

In view of the weak binding force of the existing trust model towards network node, this article proposes a group trust model. Referring to the group structure of social relationships, this model combines the nodes with the same attribute into a group. The node in the group not only has individual single trust attribute but also has the group trust attribute. Compared with other models, this model can enhance the binding force towards the network node, reduce the frequency of hostile attack and encourage the node to make a good behavior.
