摘要
分析了传统访问控制模型的缺陷,以基于角色的访问控制模型为基础,论述了如何用证书来解决分布式环境下的认证;讨论了角色在动态管理中的作用;提出了利用用户分类来堵塞由于数据分发所造成的安全漏洞的方法。
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. ;;;
