摘要
对数据库进行加密后,如何提高密文数据的操作性能是一个非常重要的问题,而基于对偶编码函数的密文过滤技术则可很好地解决此问题。文中在给出对偶编码函数的定义后,着重分析了四种基本查询基于对偶编码函数的转换规则,并利用JAVA语言将基于对偶编码函数的密文过滤技术在医院Oracle数据库中进行了实现,最后通过实验验证了此技术对密文数据操作性能有巨大提升。
After carrying on encryption to the database,how to improve the operation performance of the cryptograph data becomes an important problem.Cryptograph filtration technology based on the pairs coding function can settle the problem perfectly.After giving the definition of pairs coding function , conversion rule of four basic query based on the pairs coding function was analyzed expressly in this paper.Cryptograph filtration technology based on the pairs coding function was actualized in oracle database by using JAVA language,in the end great promotion of the technology to cryptograph operation performance was validated by experiment.
