基于三层Client/Server软件安全控制系统

分布式系统的安全性是系统建设中的关键环节。由于分布式应用程序是涉及多用户参与的复杂的网络应用系统，安全性高、易于集成的安全控制系统将极大地方便这类应用程序的开发。在本文中，作者提出了一种基于角色的访问控制模型以及相应的身份认证与权限审查机制。然后采用三层客户／服务器模型，以组件对象的形式对系统进行了实现，在实践应用中取得了较好的效果。

Security Control System Based on Three-tier Client/Server Model

The security of distributed system is a critical link in system construction. Because distributed application program is a kind of complex network application system which involves multi-users joining, high security and easy concentrating security control system will be greatly convenient to develop this application program. In this paper, the authors presents a kind of role-based access control model and its authentication and the mechanism of right checking, then implements the system with components by using the model based on three-tier Client/Server and gets better results in practice and application.
