Quantum Encryption Key Manager User’s Guide 1

Chapter 1

1Overview

Data is one of the most highly valued resources in a competitive business

environment. Protecting that data, controlling access to it, and verifying

its authenticity while maintaining its availability are priorities in our

security-conscious world. Data encryption is a tool that answers many of

these needs.

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

encrypting data as it is written to compatible data cartridges. Encryption

is performed at full line speed in the tape drive after compression.

(Compression is more efficiently done before encryption.) This new

capability adds a strong measure of security to stored data without the

processing overhead and performance degradation associated with

encryption performed on the server or the expense of a dedicated

appliance.

This chapter covers:

• Library Managed Encryption

• Managing Encryption With Q-EKM

• Quantum Encryption Key Manager (Q-EKM) Components

• Encryption Keys

• Encryption Certificates
