摘要
本文分析了约束RBAC中两种授权约束机制——SSD和DSD,指出它们无记忆性的不足,提出了将有限状态机与RBAC模型结合起来,构成一种新型的FSM_RBAC模型,最后通过示例讨论了该模型的应用。
In this paper,the SSD and DSD of constrained RBAC are analyzed,and their disadvantage of memoryless is pointed out.A new FSM_RBAC model,which is the combination of finite state machine and RBAC model,is presented,and its application is discussed through an example.
