摘要： 通过对基于角色转授权模型(RDM)的深入研究和对基于角色访问控制模型(RBAC)的扩展,提出基于角色上下文的转授权模型(RCBDM).该模型引入角色上下文和转授权规则作为转授权的依据,通过对转授权极限值、转授权域、转授权类型及转授权撤销类型等属性和各种转授权规则的定义,支持灵活的基于角色转授权(RBD)和多步转授权的实现,允许系统安全管理员对系统进行宏观安全控制.通过具体转授权应用示例充分证明RCBDM的有效和实用性.

Abstract: A rolecontext-based delegation model (RCBDM) is developed through studying the role-based delegation model (RDM) and extending the role-based access control model (RBAC). This model introduces rolecontext and delegation rules as the criterion for delegation. Rolecontext components including such attributes as delegation maximum and the domain, type and revocation type of delegation and relevant rules are defined to support the flexible and multi-step delegation, thus enabling system security management to control macroscopically the system at a higher level. Moreover, a delegation application example is given, by which the RCBDM is proved effective and useful.
