YU Min~1,YU Wen-sen~2 (1.Department of Gratuated Students,Jiangxi Normal University,Nanchang 330027,China; 2.Institute of Computer Sci.& Tech,Jiangxi Normal University,Nanchang 330027,China)  
In this paper,we introduce the role-based access control model, analyse the role hierarchy model and the problem of private permissions in RBAC96, and point out the disadvantage of Sandhu's solution. An improved role hierarchy model is introduced against the drawback of RBAC96;some new concepts such as public permission, private permission and scope of inheritance are presented in the model. In the role hierarchy model, the senior role inherits public permissions from junior role but not private permissions. Thus a new role hierarchy model is for mulated. It is simpler and more comprehensible to describe the same role relationships in the improved model than the RBAC96. It will be flexible and suitable in large-scale role hierarchies, such as operating systems, DBMS, distributed applications, etc.
