基于RBAC模型车辆管理系统权限管理设计与实现

Design and Implementation of Rights Management for Vehicle Management System Based on RBAC Model

从系统开发的角度提出了基于RBAC模型车辆管理系统权限管理的设计与实现关键技术。系统实现中,利用枚举类型实现用户权限编码,通过TreeView控件显示权限树,使用二进制位运算计算用户权限,并借助存储过程转换用户及角色操作规则。这既增强了车辆管理系统的安全性,又为RBAC模型的扩展与应用提供了参考。

From the perspective of system development, this paper presents some key technology about the design and implementation of rights management for Vehicle Management System based on RBAC Model. In the realization of the system, enumeration type is used to code the user＇s rights, the Tree- View Control in. net is employed to display rights tree, and user＇s rights are computed based on Binary bit arithmetic. At last, the paper transforms the former rules about users and roles by utilizing Stored Procedure in database. That enhances the security of Vehicle Management System and provides a refer- ence for the RBAC model＇s extension and its application.
