一种信任域下的动态细粒度访问控制方法研究
RESEARCH ON DYNAMIC AND FINE-GRAINED ACCESS CONTROL BASED ON TRUSTED DOMAIN
摘要
Abstract
In trusted domain, the large number of subjects, many types of objects, complex and volatile environment all challenge traditional access control. Traditional access control policy is not flexible enough and is difficult to achieve fine-grained permissions. To address the problems above, a dynamic and fine-grained access control method is proposed. The method is based on RBAC model but increases the constraint condition. During its implementation the PEP fine-grained component is increased at policy execution point PEP. The method reflects the dynamic and fine-grained properties of the access process, meets the dynamic and fine-grained access control requirement in trusted domain.关键词
