Encryption Highlights
Key AES-256 data encryption with a secret 256-bit encryption key is used
to encrypt and decrypt data. The key is not retrievable from the encryption
core and is automatically erased during the unload process; software is
required to extract the key, keep it secure, and provide management tools
to track, store, use, and delete keys as appropriate.
Notes: The encryption performed by encryption-enabled LTO-4 or
later generation drives is not compatible with the encryption
performed by an encryption-enabled F-QIP.
Spectra TKLM key management is not compatible with
BlueScale Encryption key management, because they cannot
share encryption keys. Data encrypted using Spectra TKLM
key management cannot be decrypted using BlueScale
Encryption key management, and vice versa.
For more information about encryption, see the Spectra Encryption User
Guide.
