Research on Database Encryption

对当前数据保密迫切性,数据库加密方式进行了详细的介绍和分析,并在此基础上,对基于密文查询的几种方法进行了深入的探讨,比较了他们相对的优缺点,提出了未来数据库加密机制需要努力加以解决的问题。

By introducing and analyzing the imminency of data encryption and database encryption mode detailedly, this paper discussesseveral method based on cryptograph query in depth, and then makes a comparison to their relative advantage and disadvantage. Lastly,this paper proposes some problems needed to be resolved for the development of database encryption mechanism.
