Multi-granularity Time-constraint Role-based Access Control
The research work of basic Role-based access control RBAC is greatly emphasized in recent years.However, many of present works have nothing to do with the time character. After detail analysis about the RBAC 2004 model, a new RBAC model with multigramdarity time character called MG-TRB,4C is proposed.In our new access control model, user,object, permission and roles are all temporal sensitive.Time constraints are measured by more than one granularity and can be implemented implicitly. The most interesting character in our access control model is that MG-TRBAC can adjust the minimum time unit threshold automatically; therefore, our access control model can save time and computational work deeply and efficiently.
