| 摘 要： | 基于权限的委托模型PBDM实现了权限的委托,其实现方法是将角色进行划分,使组织的角色继承关系变得复杂,模型的实现和管理变得烦琐.为此,提出对PBDM进行改进的基于权限划分的新模型CPPBDM,模型引入新的角色间关系:委托继承、激活指派;新模型能够实现基于权限的委托与角色代理,简化了模型的实现与管理.

| Abstract: | Although Permission-based Delegation Model(PBDM) supports permission-based delegation,it makes role hierarchy complicated and implementation and management of the model over elaborate because the roles are divided into different layers.Therefore,an improved model named Compartmentalizing Permissions in Permission-based Delegation Model(CPPBDM) is proposed,which is built on PBDM.In CPPBDM,there are two new layers of role-to-role relation: delegation inheritance relation and activation assignment relation.CPP... |
