摘要
基于角色访问控制(RBAC)技术的一个重要概念就是角色,通过在用户和访问权限之间增加一个角色层,使得权限控制更为简单且灵活有效。文章分析了RBAC96模型,并结合一个办公自动化系统的具体应用,对模型进行扩充,提出了业务角色的概念。
One of the important concepts in role-based access control （RBAC） technique is the role, which makes the priority control simpler, more flexible and more efficient by adding a role-layer between the user and the access priority. The RBAC96 model is analyzed and extended, and eventually the concept of ＂business role＂ by combining a specific application in an office automation system is proposed.
