abstract = "We describe in more detail than before the reference
model for role-based access control introduced by
Nyanchama and Osborn, and the role-graph model with its
accompanying algorithms, which is one way of
implementing role-role relationships. An alternative
role insertion algorithm is added, and it is shown how
the role creation policies of Fernandez et al.
correspond to role addition algorithms in our model. We
then use our reference model to provide a taxonomy for
kinds of conflict. We then go on to consider in some
detail privilege-privilege and role-role conflicts in
conjunction with the role graph model. We show how
role-role conflicts lead to a partitioning of the role
graph into nonconflicting collections that can together
be safely authorized to a given user. Finally, in an
appendix, we present the role graph algorithms with
additional logic to disallow roles that contain
conflicting privileges.",
