采油厂保密信息管理系统的设计与实现

The Design and Implementation of Confidential Information Management System for Oil Extraction Plant

为了充分利用采油厂的大容量磁盘系统,安全保存本厂员工的重要资料,采用AD技术实现帐户的统一管理.运用多层数据库和组件技术实现信息管理.通过对用户密钥进行MD5加密和文件内容的3重DES加密保障了数据的安全,即使是管理员也无法看到文件的内容.本系统具有安全、方便、快捷的特点,为大中型企业提供了企业级信息服务的解决方案.

The main purpose of the system is to make full use of the large-capacity disk drive provided by the oil extraction plant and store the significant resource safely. In the paper, it adopts AD technology to implement unified management of the users. Multilayer database and COM technology are used for information management. Users＇ password is encrypted by MD5 algorithm and file content is encrypted by 3DES to ensure the data security, even the administrator can＇t see the original words. The system＇s features are security, convenience and quick operation, it provides a solution of information management for large and medium-sized enterprise.
