【Abstract】 The ARBAC97,ARBAC02 and Crampton-Loizou models make an important contribution to the understanding and modeling of administration of role-based access control.However,there are several features of the three models which we believe could be improved.In this paper,the concept of administrative domain is introduced and is used to manage RBAC model.A hierarchical administration model is proposed for role-based access control(HARBAC) and is compared with the above three models.Based on the comparison,the proposed model has some significant advantages over those three models.更多还原
