Abstract

The use of the graph-based framework to specify the administration of RBAC systems has several advantages, from the intuition provided by the visual aspect to the precise semantics and the systematic verification of constraints. Here the benefits of this framework are illustrated using SARBAC (scoped administration of role based access control), providing the first steps towards its operational semantics and a more expressive constraint language.
