| 摘 要： | 针对基于属性的访问控制模型(Attribute-Based Access Control,ABAC)存在的静态策略冲突及冗余问题,提出了一种基于属性集有序化及二进制屏蔽码的静态策略冲突检测算法。该算法能够检测出全部的静态冲突,相对于目前典型的暴力算法与属性分割算法,降低了时间复杂度和空间复杂度；同时支持属性的新增及策略的新增或删除,能够更好地满足现代复杂网络环境的要求。

| Abstract: | A static policy conflict detection algorithm based on ordered attribute set and binary mask key was proposed.The algorithm can detect all of the static policy conflicts and redundancy in attribute-based access control model. Compared with the typical violence algorithm and the attribute segmentation algorithm,the proposed algorithm can reduce the time complexity and space complexity .Furthermore,it supports adding and removing attributes from set.New algorithm can meet the requirements of modern complex network environments. |
