摘 要: 本文针对当前权限控制框架在权限控制和数据保护方面存在的问题,提出一种新的权限控制解决方案——基于RBAC的限制约束扩展。文章重点描述了限制约束功能的原理与实现,并对限制约束扩展应用时出现的限制冲突和限制共享问题,提出了解决方法。 The paper analyses the problems which exist in the privilege control and data protection of the current privilege control framework and makes an extension on the privilege control frame, which is limit constraint support based on RBAC. The paper de- scribes in detail on how to realize the limit constraint support in the current system. Finally we solve the problems on the limit con- flicts and limit share, which are caused by the application of the limit constraint support.
