Role-based dynamic access control for Web services

After reviewing the state of the security technology research and access control in the Web services environment, this paper presents a dynamic role-based access control (UE-DRBAC) model through user life cycle events and a secure architecture model for Web services. A reasonable access control is used to achieve the dynamic authorization by analyzing the relationship among roles based on user life cycle events, and authorization process algorithm is discussed in detail. Finally, it is the conclusion and further research.
