基于时间角色访问控制授权模型的研究

Research on Authorization Model Based on Time RBAC

基于角色的访问控制作为一种新型的访问控制技术成为近年来访问控制领域研究的热点,但目前主要工作均立足于与时间特性无关的其他方面。在基于角色访问控制的几种主要模型的基础上,提出了一种基于时间的角色访问控制模型。引入时间的目的是使系统更加安全有效。充分体现了TRBAC模型更能满足信息安全管理的需求,使扩展的TR-BAC模型更能适应系统的需求。

As a new access control technology, role-based access control has been very popular in that research field in recent years, but the main work focus on some other characters which has nothing to do with the time character. Synthesizes main models of role- based aceros control and designs a time role - based access control model which is called TRBAC model. Introducing time is to make the system more safe and effective. TRBAC can meet the needs of information security and satisfy the systems better.
