In order to improve the user access control effect of power marketing system, a user rights allocation method for power marketing system based on RBAC model is proposed. Use the trust attribute to expand the access strategy expression, obtain the global trust of power marketing system information resources and control access rights by monitoring users' access behavior; Based on the results of access control, the role-based access control (RBAC) model and the mandatory access control model are analyzed, and the concept of role is introduced. User rights access level is obtained by quantifying the trust of different access behaviors among users when assigning rights, and the user rights are assigned. The results show that the user access control time of the proposed method is shorter, the error rate of user rights allocation is lower, and the degree of user satisfaction is improved.
