Abstract
A database management system (DBMS) performs encryption in a DB. The system receives authentication authorization regarding a security policy of the DB from an external encryption unit that is separated from the DB and performs encryption. Important data in a column unit is selectively encrypted and an encrypted comparison code (ECC) of the important data is generated inside the DB. The encrypted important data and the corresponding ECC is generated as a single encryption data type.
