Abstract

This chapter presents R+DRC, an extension of the Role-based Access Control (RBAC) model. R+DRC allow for defining constraints, for example to enforce different forms of separation of duties, and the right of overriding a constraint. The model also defines delegations, and two forms of revocations. The model is discussed within the framework of modeling the access control of an hospital. Algorithms are provided for the more complex actions.
