The model is formed from the second abstract of the resource during the course of role authorization and the implementation of security policy. Thus , the reduction of role redundant role and management complexity is obtained. The scheme is vertified by the case in management system of university. Compared with traditional RBAC, RD_RBAC is of more applicability and more security.
