The paper presents revocation schemes in role-based access control models. We are particularly interested in two key issues: how to perform revocation and how to manage the revocation policy. We show how to deal with these two aspects in the delegation model based on the OrBAC formalism and its administration licence concept. This model provides means to manage several delegation types, such as the delegation or transfer of permissions and roles, multi-step delegation and temporary delegation.doi:10.1007/978-3-540-88625-9_13 fatcat:3i54tux4y5dmjohw2nrpcd233i
