为解决访问控制策略的安全性分析问题

提出了一种基于信息熵的策略量化分析理论.首先

根据信息论中加权熵的知识定义了策略安全熵

提出了非授权访问行为的最大不确定性计算方法.然后

分别给出了典型访问控制策略的一维安全熵和

维安全熵

并对结果进行了证明.最后

依据安全熵分析了典型访问控制策略的安全性.

To resolve the problem of security analysis to access control policy

a quantitative analysis theory is proposed based on information entropy.Firstly

the policy security entropy is defined according to Entropy-Weigh

and computing way for uncertainty of unauthorized access behaviors is bring forward.Then

the security entropy of one dimension and

dimensions of typical policies are given

and the results are proved.Finally

the lackage and change trend of typical policies' security are analyzed.
