摘要
随着数据库技术在日常经济生活中应用的不断增加,数据库安全日益成为人们关注的热点。而目前数据库的安全性主要通过访问控制来保障,但是当访问控制被攻破时整个数据库的安全体系也随之瓦解。目前解决此问题的主要方法是采用数据库加密。文中对目前主要的几种数据库加密方法进行了探讨和研究,并指出了数据库加密的发展方向。
With the development of database usage into economy and production of our daily life, the database security is more and more concerned. Nowadays the main technology used in the database security is access control,but when the access control mechanics is broken through, the whole security system is collapsed. Database encryption is introduced to solve this problem. Several technologies of database encryption are discussed in this paper, as well as the direction of corresponding researches.
