ABSTRACT:
Query processing system and method by query transformation transform a user request query based on an original DB structure, destined to a DBMS of a DB with some columns encrypted, into a query based on an encrypted DB structure so that the DBMS processes the query. The query is processed irrespective of whether or not the query includes an encryption-related item, and query-processing performance is remarkably improved.
