Keep Master Key Labels Unique
Description
Db2 uses the MK label to uniquely identify each MK, and stores the label value in each encrypted object, be it a database, transaction log, or backup file. This stored MK label value identifies the MK key material that is used to decrypt the data in the object. Creating MK labels is part of an organizations standard operating procedures (SOP).
