摘要： Methods, systems, apparatuses, and computer program products are provided for processing queries. A data server includes a query processor configured to receive a query from a database application, which was received by the database application from a requestor. The query is directed to data stored at the data server. The query processor includes a deferred evaluation determiner and deferred expression determiner. The deferred evaluation determiner is configured to analyze the query, and to designate the query for deferred evaluation by the database application if a predetermined factor is met, such as the query including an operation on encrypted data that is not supported at the data server. The deferred expression determiner is configured to determine expression evaluation information for evaluating at least a portion of the query at the database application. The query processor provides the encrypted data and the expression evaluation information to the database application for evaluation.

摘要： 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.

摘要： Systems, methods and computer program products are described that analyze the code of an application and, based on the analysis, identify whether data elements (e.g., columns) referenced by the code can be encrypted, and for those data elements that can be encrypted, recommend an encryption scheme. The recommended encryption scheme for a given data element may be the highest level of encryption that can be applied thereto without affecting the semantics of the application code. The output generated based on the analysis may not only include a mapping of each data element to a recommended encryption scheme, but may also include an explanation of why each recommendation was made for each data element. Such explanation may include, for example, an identification of the application code that gave rise to the recommendation for each data element.
