Master Key - NEC T30A User Manual

6.1.3.1 Master Key

You must always set the master key when using this encryption management function.
The master key has the following two roles:
(1) Used when multiple Libraries share tape medium.
(2) Used to automatically generate encryption keys for each tape media.
1. Sharing tape media using the master key
If you set the same master key to multiple Libraries, these devices can share tape medium
without regard to the encryption key.
Management console (WEB)
If encryption keys are individually set to each tape medium, tape medium cannot
be shared even if the same master key is set. When using such encryption keys,
import the corresponding encryption key into the Library every time you import
tape media into the Library.
2. Automatic generation of encryption key
This Library automatically generates different encryption keys for each tape medium from the
master key and the serial number recorded in the tape medium. If different Libraries have the same
master key and tape media serial number, the same encryption key is generated.
