We present a model for delegation that is based on our decentralized administrative role graph model. We use a combination of user/group assignment and user-role assignment to support user to user,permission to user and role to role delegation. A powerful source-dependent revocation algorithm is described. We separate our delegation model into static and dynamic models, then discuss the static model and its operations. We provide detailed partial revocation algorithms. We also give details concerning changes to the role hierarchy, user/group structure and RBAC operations that are affected by delegation.
