权限管理中间件的研究与实现

研究了与权限管理中间件有关的关键技术——访问控制技术和中间件技术,设计了权限管理中间件的结构,在分析经典层次化RBAC(Role-based access control,基于角色的访问控制)模型角色更改困难的基础上,提出了一种新的层次化RBAC模型,将层次化RBAC模型中角色之间的继承关系转移到权限中。在上述研究的基础上开发了具有自主版权的权限管理中间件,并与洪都航空工业集团公司的信息系统实现了无缝集成,应用于该公司两种型号飞机的研制。

Research and Realization of Permission Manage Middleware

Based on the practice of the development of the permission manage middleware, this paper discusses two key technologies of the permission manage middleware-access control and middleware. The structure of the permission manage middleware is designed. Based on the analysis of the classic hierarchical RBAC model, a new hierarchy RBAC model is presented and the inherited relation between the roles is transformed to the inherited relation between the permissions on hierarchical RBAC model. The above research achievement is used to the development of the permission manage middleware. The middleware technology is seamlessly integrated in the information system at Hongdu Group Company of Aeronautical Industry and the manufacture of two kinds of planes.
