摘要
在研究RBAC模型的基础上,通过引入访问控制分层管理的思想来改良和扩展RBAC模型,建立了SaaS(软件即服务)系统的一种权限管理模型。从系统访问许可证、系统功能操作控制、系统数据访问控制三个层次建立了结构模型,并对其做了形式化定义。最后指出了新模型的优点。
Based on the research of RBAC model,the thought of access control with layered management is imported to improve and extend the RBAC model,and a permission management model of SaaS system is built up. Then,the structural model is established from three aspects of access permission card,functional operation control and data access control,together with a formal definition given. At last,the advantages of the new model are pointed out.
