保序加密方案被认为是保护数据库中数字数据的最有效的加密技术之一。这种方案很受欢迎，因为它们解决了性能下降问题，而性能下降问题一直是数据库加密中的重要问题。但是，在某些应用程序中，订单本身是敏感信息，应该保留。迄今为止发表的传统的保序加密技术并没有考虑到这个问题。因此，在本文中，我们考虑了两种性能良好且保护订单信息的技术。一种是对原始值进行扰动。另一种使用基于树的顺序隐藏技术。这两种方法隐藏了数据的顺序，可以有效地处理比较运算符，防止性能下降。我们的方法工作在保序加密方案之上，提高了数据的安全性。实验结果表明，本文提出的两种加密方法比基线方法和其他加密方法更有效。
Order preserving encryption schemes have been considered as one of the most efficient encryption technique for securing numeric data in a database. Such schemes are popular because they resolved performance degradation issues, which have been significant problems in the database encryption. However, in some applications, the order itself is a sensitive information and should be preserved. Conventional order preserving encryption techniques that have published so far did not consider the issue. Therefore, in this paper, we considered two techniques that perform well and also protect the order information. One uses perturbation of original values. The other uses tree based order hiding technique. The two methods hide the order of data in such a way that can efficiently handle comparison operator and prevent performance degradation. Our methods work on the top of order preserving encryption scheme and enhances the security of data. Our experiment results show the efficiency and effectiveness of proposed two methods over baseline method or other encryption.
