%X The traditional role based access control model (RBAC) can not avoid some security flaws, because the components and the constraints of the model are too simple. Based on the traditional RBAC, a enhanced RBAC model (ERBAC) was brought forward, which expanded the components and the constraints. Besides, this new model features the separated administrative permissions, complete constraints and better utility.
