在基于角色的访问控制(RBAC)模型的基础上,提出一种多级权限访问控制模型。该模型采用树形结构进行权限的多级分配,细化权限控制粒度,能够更加灵活地对系统进行访问控制,满足大多数系统的访问控制授权方案。
Based on the role-based access control (RBAC) model, a multi-level access control model is proposed. The model uses tree structure to distribute multi-levels of authority and granularity of authority control. It can control access to the system more flexibly and satisfy the access control of most systems.
