基于RBAC的灵活集团委托模型

Flexible Group Delegation Model Based on RBAC

针对现有基于RBAC的委托模型不支持集团用户委托形式,提出一种基于角色的灵活集团委托模型,给出了委托关系、委托授权、委托撤销的形式化描述及委托实施过程。该模型提供了一种灵活的委托机制,实现了在分布式协同工作环境下从单个用户到集团用户的统一委托。

Aiming at the problem that the existing delegation models based on RBAC did not support group delegatiom,this paper proposed a role-based flexible group delegation model.Delegation relation,delegation authorization,revocation and the process of delegation were presented.The model presents a flexible mechanism of delegation,and accomplishs the unified delegation from some user to group users in the distributed collaboration of work.
