浅谈数据库加密的实现及目标

Research on Encription in Databases

在分析数据在本地数据库存储现状的基础上,提出了要对数据库本身进行加密操作,以解决数据安全问题。总结了数据库加密实现要解决的层次定位、加密项和加密粒度的确定、加密算法的选择和密钥动态管理等问题,给出了一些解决方案,并提出了数据库加密应达到的基本目标。

In the analysis of the storage state in the local databases, a conclusion is drawn in this paper that it is significant and necessary to encrypt databases for the security of data. Meanwhile, the related issues are summarized, including the determination on the hierarchical location, the encryption item and the granularity of encryption, the selection on the encryption algorithms and the dynamic management of keys. In addition, several solutions are given and the goal in the encryption of databases is proposed.
