Abstract: In this paper, the limitation of traditional access control models is firstly analyzed. Then, based on the role-based access control, the problem of how to use certificate to resolve the authentication in distributed environment gets further analysis,the function ofthe role which works in dynamic management is discussed.At last the method of user-grouping is at last put forward to fill up the security leak out of data dispensing. ;;;
