SA-RBAC: An Innovative Role-Based Access Control Model Introducing Self-Authentication Mechanism

According to the existing problems in access control model: privilege abuse and neglecting high security grade of sensitive information in practical application, an innovative access control model SARBAC is proposed in this paper. It introduces selfauthentication mechanism into the Reference RBAC Model. A theoretical description of self-authentication mechanism is given at first, and the follow is a systematical formal presentation of SA-RBAC on the base of Core RBAC Model. Several key issues on the new model are discussed as well.
