Library Managed Encryption

The library managed tape drive encryption solution is composed of the

following elements:

• Encryption-Enabled Tape Drive

• Quantum Encryption Key Management (Q-EKM)

• Encryption-Enabled Tape Library

Encryption-Enabled Tape

Drive 1

IBM LTO-4 and LTO-5 Fibre Channel and SAS tape drives are encryption-

capable. This means that they are functionally capable of performing

hardware encryption, but this capability has not yet been activated. In

order to perform hardware encryption, the tape drives must be

encryption-enabled. They can be encryption enabled via the tape library.

SCSI IBM LTO-4 tape drives are encryption aware (they can load and

handle encrypted LTO-4 cartridges, but cannot process encryption

operations).

See Supported Libraries and Tape Drives

on page 10 for a list of which

tape drives are supported by your library.

Quantum Encryption Key

Management (Q-EKM) 1

Encryption involves the use of several kinds of keys. How these keys are

generated, maintained, controlled, and transmitted depends upon the

operating environment where the encrypting tape drive is installed.

Some host applications are capable of performing key management. For

environments without such applications or those where application

agnostic encryption is desired, Quantum provides the Quantum

Encryption Key Manager (Q-EKM) component for the Java platform to

perform all necessary key management tasks. Managing Encryption With

Q-EKM on page 3 describes these tasks in more detail.

Encryption-Enabled Tape

Library 1

On an encryption-enabled library, tape encryption occurs automatically

and transparently. The library communicates with the EKM server to

obtain encryption keys for the drives to read from or write to encrypted

data to the tapes.
