Abstract:

Role-Based Access Control(RBAC) have been adopted bythe electric power information system rely on its reliable security and flexibility of authorization. But due to the popularization and expansion of Intelligent acquisition equipment and the electrical powersystem, combined with the stricter security requirement of electrical informationsystem, the security issues exposed when the traditional RBAC model be applied to the electric power information system. This paper put forward a kind of safety optimized RBAC model. In this model, we import the concept of SG(Supervise Group) and the machine-made of the supervision of sensitive permission to expand the traditional RBAC in safety field. In this paper,the generating algorithm of SG and the pseudo code, flow chart of the optimized model is also be given.An example is given to show that the proposed algorithm can effectively supervise the sensitive permission and enhance the security of the electric power information system while satis-fying the function of it.

Key words: role-based access control(RBAC), information security, electric power information system, permission supervise
