中文摘要: 为了解决数据库加密后查询效率低的问题，针对数据库加密技术的实际应用，提出了一些解决方案。通过对数值型密文数据使用标志位，为字符型数据创建外存索引文本，缩小了查询范围，提高了数据查询效率。最后进行实验测试分析，证实了方法的有效性。
Abstract:In order to solve the problem of querying inefficiently on encrypted databases, some solutions are proposed in this paper based on practical application of database encryption techniques. Through setting marks for encrypted numerical data and creating index text in external memory, the range of querying is reduced, then the efficiency is improved. Finally, some tests are performed to validate the solutions.
