摘要
针对以往用户和权限直接相联系的这种存在很大安全隐患的问题，将具有相同权限的用户组合成一个角色，节省了存取矩阵空间。该系统的角色管理模块结合了基于角色的访问控制模型的优点，充分的满足了高校实现数字化校园的需求，并且也适合其他需要角色分配的应用系统。
The paper solved these great hidden safety problems coursed by the users and the authority linked directly, and combined the users who owned the same authority as a role, which saved space of access matrix. Combining the merits of RBAC model in the role management module of the system, the colleges can meet the needs of Digital Campus, and also fit other needs of the distribution of roles application systems.
