| 摘 要： | 通过深入分析MAC模型和RBAC模型,提出了一个扩展RBAC的安全约束实现强制访问控制的方法.其特点是利用信息流分析原理把每个角色上下文看成一个安全标示并确保信息流由角色执行或用户角色授权是非循环的通过给出的相关约束实现了模型的有关规则.

| Abstract: | By deeply analysing the concept of MAC model and RBAC model,this paper put forward a method to realize MAC in the security constraint of extended RBAC by viewing each of the role contexts as a independent security-level and imposing non-cyclic information flow requirement. |
