On XACML‚ role−based access control‚ and health grids
David Power, Andrew C. Simpson, Mark Slaymaker · 2005
In this paper we discuss the use of XACML policies to describe access control for use in health grids. We discuss the motivations for the use of role-based access control (RBAC) in a medical context. Using a simple motivating example we consider the use of the RBAC profile for XACML and discuss the limitations of the current profile. Finally, we discuss various solutions to providing fully flexible RBAC support in XACML, and consider their impact on the existing language. 1.
