DATABASE SERVER AND CLIENT FOR QUERY PROCESSING ON ENCRYPTED DATA

Methods, systems, apparatuses, and computer program products are provided for secure handling of queries by a data server (DS) and a database application (DA). A parameterized query is received by the DS from the DA based on a user query received from a requestor. The DS analyzes the parameterized query to attempt to determine an encryption configuration for a transformed version of the user query capable of being evaluated by the DS on encrypted data values. The DS responds to the DA with either a failure to determine the encryption configuration, or by providing the determined encryption configuration to the DA. The DA generates the transformed version of the user query, and provides the transformed version to the DS. The DS evaluates the transformed version of the user query, and provides results to the DA. The DA decrypts the results, and provides the decrypted results to the requestor. 提供了方法、系统、装置和计算机程序产品，用于数据服务器(DS)和数据库应用(DA)安全处理查询。基于从请求者接收的用户查询，DS从DA接收参数化查询。DS分析参数化查询以尝试确定用户查询的转换版本的加密配置，转换版本能够被DS在加密数据值上
