To address the issue,by adding an element called as importance level of privilege in RBAC model,a fine-grained role-based access control model is presented,which is denoted as FGRBAC.
针对这个问题,在RBAC模型中增加权限的重要程度要素,提出了FGRBAC模型(Fine-Grained Role-Based Access Control Model--细粒度的基于角色的访问控制模型),并给出了在FGRBAC模型中求用户权限和角色权限的算法。
