摘要:

P2P网络的开放性自组织等特性给系统带来一系列的安全风险,然而传统的访问控制模型并不能适用于P2P网络这样的分布式管理系统。针对该问题,给出一种基于模糊理论的任务访问控制模型,并对该模型进行形式化描述与分析。通过层次分析法和模糊评价模型,计算每次交互任务的风险值。该模型通过对任务访问控制模型进行扩展,依据交互任务的风险值对访问权限进行动态管理。分析与实验结果表明该模型能够抑制非合作节点的交互成功率,增大整个对等网络系统的交互成功率,提高了对等网络系统的安全性。

Abstract:

The opening and self-organization features of P2P network brings a series of security risks,andthe traditional access control model is not suitable for P2P network as it is a kind of distributed management system.Task-based access control mode of P2P network was proposed based on fuzzy theory.And the formalization description and analysis of the model was also proposed.The risk value of each transaction was calculated through hierarchy process analysis and fuzzy comprehensive evaluation.In this model,according to the risk value of each transaction,the dynamic management of ac-cess authority was realized by extending task-basedaccess control model.The results show that this model can restrain the success of noncooperative nodes transaction and raise the success of the whole P2P network system transaction,thus improving the security of P2P network system.
