摘　　要：伴随大数据、云计算以及人工智能等IT技术的飞速发展,数据库被广泛应用于各个行业。面对严峻的网络安全形势,数据库安全问题日益突显。保序加密是一种提供数据加密同时实现密文大小比较、范围查询的技术,能够在实现数据安全的同时,保障数据库查询、比较等业务应用,对于数据库安全有着极高的应用价值。对数据安全形势和保序加密需求进行分析,对比研究保序加密技术,提出了不同场景下适用的保序加密方案,给出了数据库保序加密应用建议,可为数据库安全提供技术支撑。With the rapid development of IT technology, such as big data, cloud computing and AI, databases are widely used in various industries. Facing the severe situation of network security, the problem of database security has become increasingly prominent. Order preserving encryption is a technology that provides data encryption and realizes ciphertext-based data comparison and range query. It can realize data security and guarantee database query, comparison and other business applications. It has high application value for database security. This paper analyzes the data security situation and the requirements of order preserving encryption, compares and studies the order preserving encryption technology, puts forward the applicable order preserving encryption schemes in different scenarios, and gives the application suggestions of database order preserving encryption, so as to provide technical support for database security.
