Local key management mode

Local Key Management Mode, or Local Mode, is a solution designed for small to medium-size data centers using few encrypting controllers. The solution utilizes a paraphrase password, or Master Encryption Key name, to set the security on the controller and enable encryption. The paraphrase password must be tracked independently of the controllers, in case the controller needs replacement or drive migration is required among controllers with different passwords. In local mode, the Master Key name is considered a cryptographic secret and should be protected as such. Key creation and management is maintained at the local controller level without the use of a key manager.

Characteristics

•Requires physical paraphrase password management, such as writing and storing Master Key information in a notebook or computer file

•Utilizes one paraphrase password-derived 256-bit key to encrypt a unique, per-volume XTS-AES 256-bit data encryption key

Prerequisites

•An installed HP Smart Array Controller compatible with HP Secure Encryption

•A valid HP Secure Encryption license for each drive to be encrypted

•HP Smart Storage Administrator v1.60.xx.0 and later

•HP ProLiant Gen8 or later server

Configuring the controller (local mode)

IMPORTANT: HP recommends that you keep a record of the Master Encryption Keys when encryption is configured in Local Mode. The local Master Encryption Key is not displayed by any available tool or firmware because it is considered a cryptographic secret by FIPS 140-2. HP Secure Encryption design follows the NIST architecture requirements and does not allow HP to assist in the recovery of a lost Master Encryption Key.

To configure the controller to operate in Local Key Management Mode:

1.Open Encryption Manager ("Opening Encryption Manager" on page 33).
