基于DES的数据库保密研究

Study on DES Database Confidentiality

介绍了DES的工作流程,分析了数据库保密的基本原理,论述了如何使用DES算法完成对关系数据库敏感数据的保密及使用Java语言实现数据库表级、字段级和数据项级的加密保护,提高应用系统的安全性。

The article introduces the work flow of DES, the principle of database confidentiality. And on this base, through Java, the way of using DES to achieve the secrecy of relational database and implement the encryption of data at the table level, field level and item level are discussed to enhance the security of applicable system.
