带有时间约束支持冲突检测的访问控制模型
An Access Control Model of Supporting Conflict Detection with Time Constrains
摘要
Abstract
In order to ensure the policies stored in the system are conflict-free,to improve the efficiency of strategy conflict detection and make the system operated correctly and effectively,apply the concept of ontology into the access control and propose an ontology-based access control model of supporting policy conflict detection,and has described policy detection engine in detail which is the core of the model. On this basis,the model has introduced the time constrains to make the system of authorization has timeliness. Then the resources can be divided into 4 categories according to the characters of the time constrains for corresponding to the reality,enhancing the capability of system authorization. Finally,propose a time constrains algorithm for this model according to the access control of four resource.关键词
