摘要
设计并实现了一种基于ＯＲＡＣＬＥ７的多级安全加密管理系统．引入角色控制、强制访问控制和数据库加密技术，实现了“记录级”加密粒度的多级安全系统，并给出了系统的具体设计方法．实践证明在现有商品化关系数据库系统上构造安全外包，在技术上是可行的，是一条建立实用安全系统的有效途径．
The design and implementation of a security management system based on ORACLE 7 is introduced. It offers Role Based Access Control (RBAC), Mandatory Access Control (MAC), and database encryption technology. The system features its “row level” security, and detailed steps to construct the system are given. It is proved that its feasible to build a secure access wrapper for current commercial RDBMS, and it is an efficient way to construct a secure system for practical applications.
