Abstract: By introducing the idea of using RBAC itself to manage RBAC,a new self-administrative delegation model APBDM is presented on the basis of PBDM,and its main idea and architecture are discussed.The new model sets up more convenient and flexible authorization and revocation policies,and solves limited permissions delegation;so as to it will be extensively used in decentralizing network and workflow management systems.
