Abstract

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.

Description

Background technique [0001] Data can be stored locally or remotely according to various storage configurations and implementations. For example, cloud computing is the latest development related to the deployment of networks of remote servers and software that provide centralized data storage and online access to resources and services, known as "cloud services." A group of cloud servers can host resources / services for a single user (“tenant”) or for multiple related or unrelated users (“multi-tenant” system). Similarly, data can be stored by an entity "onsite" and can be accessed by that entity in that onsite data store. [0002] Data breaches can be a major factor inhibiting the adoption of cloud services for applications that manage sensitive, business-critical information. On public clouds, applications must guard against potentially malicious cloud administrators, malicious co-tenants, and other entities that can gain access to data through various legitimate means. Si...
