IBY_SYS_SECURITY_SUBKEYS

IBY_SYS_SECURITY_SUBKEYS stores the security sub-keys used for data encryption. A sub-key is a randomly generated number used to encrypt only a fixed number of data rows, after which a new sub-key is randomly generated. The sub-key is stored as cipher-text in this table.

Columns

Name	Datatype	Length	Precision	Not-null	Comments
SEC_SUBKEY_ID	NUMBER		18	Yes	Sequence-generated primary key
SUBKEY_CIPHER_TEXT	RAW	50		Yes	Cipher text of the sub-key
USE_COUNT	NUMBER		18	Yes	Number of times the sub-key was used to encrypt data
CREATED_BY	VARCHAR2	64		Yes	Who column: indicates the user who created the row.
CREATION_DATE	TIMESTAMP			Yes	Who column: indicates the date and time of the creation of the row.
LAST_UPDATED_BY	VARCHAR2	64		Yes	Who column: indicates the user who last updated the row.
LAST_UPDATE_DATE	TIMESTAMP			Yes	Who column: indicates the date and time of the last update of the row.
LAST_UPDATE_LOGIN	VARCHAR2	32			Who column: indicates the session login associated to the user who last updated the row.
OBJECT_VERSION_NUMBER	NUMBER		9	Yes	Used to implement optimistic locking. This number is incremented every time that the row is updated. The number is compared at the start and end of a transaction to detect whether another session has updated the row since it was queried.
ENTERPRISE_ID	NUMBER		18		Enterprise identifier to support multi-tenancy.
CIPHER_TYPE	VARCHAR2	30			Active cipher type.
