Abstract: This paper analyzes the administrative model of RBAC and Usage Control(UCON)model, and points out the deficiency of UCON core model. Based on the results, authorization mechanism of separated rights grant and revoke is introduced into UCON model, and a role-based usage control model with time character is presented. The description of the model and its implementation administration are presented.
Key words:
Usage Control(UCON),
Role-based Access Control (RBAC),
