行业和个人将数据库外包，以实现方便、低成本的应用和服务。为了给SQL查询提供足够的功能，已经提出了许多安全数据库方案。然而，这样的计划是脆弱的隐私泄漏到云服务器。主要原因是数据库在云服务器上托管和处理，这超出了数据所有者的控制范围。对于数值范围查询（“>”、”<”等），这些方案不能针对实际挑战提供足够的隐私保护，例如，隐私泄露的统计属性、访问模式。此外，查询数量的增加将不可避免地向云服务器泄漏更多信息。在本文中，我们提出了一个安全数据库的双云架构，一系列的交叉协议，提供隐私保护各种数字相关的范围查询。安全性分析表明，在我们提出的方案中，数字信息的隐私受到了很强的保护。
Industries and individuals outsource database to realize convenient and low-cost applications and services. In order to provide sufficient functionality for SQL queries, many secure database schemes have been proposed. However, such schemes are vulnerable to privacy leakage to cloud server. The main reason is that database is hosted and processed in cloud server, which is beyond the control of data owners. For the numerical range query (“>,” “<,” and so on), those schemes cannot provide sufficient privacy protection against practical challenges, e.g., privacy leakage of statistical properties, access pattern. Furthermore, increased number of queries will inevitably leak more information to the cloud server. In this paper, we propose a two-cloud architecture for secure database, with a series of intersection protocols that provide privacy preservation to various numeric-related range queries. Security analysis shows that privacy of numerical information is strongly protected against cloud providers in our proposed scheme.
