| 摘 要： | 根据角色的继承和委托特性,将角色分为若干个子角色,在PBDM模型的基础上提出了一种新的具有自我管理能力的支持角色层次的授权代理模型ASRBDM.本模型支持部分代理、权限级粒度代理和限制性继承,还支持用户-用户代理和角色-角色代理中的职责分离约束.

| Abstract: | A new self-administrative sub-role based delegation model ASRBDM on the basis of PBDM is proposed. It supports flexible delegation by dividing a role into sub-roles according to characteristics of permissions assigned to the role and considering delegation and inheritance simultaneously. It provides flexibility in authority management such as partial delegation, permission level delegation and restricted inheritance. Constraints such as separation of duty based on permission in user-to-user and role-to-role delegation are also supported. |
