Description
Summary:Existing context-based access control mechanisms have a problem of tradeoffs between the expressive power and the management efficiency of authorization policy. In this paper we introduce the context-aware role engineering which is a new concept for context-based access control and context-aware service scenario driven role engineering approach. The context-aware role engineering enables that context-based access control can be implemented using basic RBAC 3 model with context constraints.
