| 摘 要： | 传统P2P网络安全管理系统中,系统管理员不能及时阻止恶意用户的非法行为。本文引入信任机制对用户行为进行动态评估,并将用户的信誉度与用户权限进行动态绑定,提出了基于信任的P2P网络用户行为分析模型,设计实现基于信任的动态访问控制关键算法,及时阻止用户恶意行为。

| Abstract: | In traditional network security management systems,system administrators could not prevent malicious users from illegal actions in time.This paper introduces the trust mechanism to dynamically evaluate user's reputation which is correlated with the user's privilege in the network and based on which we proposed and implemented the key algorithm of trust based access control in P2P Network. |
