An Expanded Role-Based Access Control Model
Xiaoming Wang · Microelectronics & Computer · 2006
But most of the existing RBAC models are static,and the dynamic management for roles is required by morden software systems.With the notions,role environment function and role constraint rule used,a new model,extended role-based access control(ERBAC)is proposed,the dynamic characteristic of RBAC in special-time is extended,the new relationships among roles,the grant rules and formal descriptions are defined and discussed.Finally,a basic framework implementing ERBAC model is given.
