Zusammenfassung:	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.

The encrypted important data and the corresponding ECC is generated as a single encryption data type.
