Improvement of the SET Payment System by Using RBAC

This paper proposes a method that can improve the SET payment system using RBAC. It mainly aims at the flaws that the payment process in SET system is quite complex, and it´s difficult to save and check the payment information. The method can solve the problem of saving and checking the payment information by adding a resource server to the payment system, and realizing the access control of payment information with RBAC. Meanwhile, the improved scheme abandons the technology of dual signatures, and simplifies the process of authentication, thus simplifying the whole payment process.
