基于字段的数据库加密技术研究

The Research of Database Encryption Technology Based on Fields

提出了一种基于字段的数据库加密模型,采用DBMS外层加密方式,使用高效的AES算法对敏感字段进行加密,密钥随机生成,不同字段的密钥不同。该模型具有安全性高、加解密速度快、密钥管理简单等特点。

This paper, based on fields, puts forward a database encryption model, in which an outer encryption way of DBMS is employed, sensitive fields are encrypted by efficient AES algorithm, secret keys are randomly produced, and different fields have different secret keys. It has the merits as follows： high safety, fast speed of encryption and decryption, and easy management of secret keys.
