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
N
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
N
dimensions of typical policies are given
and the results are proved.Finally
the lackage and change trend of typical policies' security are analyzed.
