N2 - By studying the multiple granularities of time constraints' descriptions and consistency problems, in this paper, we establish a dynamic fine-grained access control model, thereby improve the access control precision, quality and efficiency. This paper describes the related concepts of time and the time constraints of multi-granularity. It proposes a kind of TRBAC model with multiple granularities of time constraints by extending the time dimension of the RBAC model. At the same time, it discusses and analyzes the maintenance of the state of the consistency of the system, which enhances the ability of system portray authority in reality and brings it with stronger, more comprehensive description of system security capabilities.
