Overview
1.1 Overview of the Data Encryption Function of LTO Ultrium
Tape Drives
LTO Ultrium tape drives that are installed in the LT140 tape library have the function to write data to data
cartridges (*2) with AES (*1) (256 bit) .
With this function, data is assigned an arbitrary key when written to a data cartridge (*2), and the data can
be read only if the same key is assigned again at the data read time. (*3)
The function can thus prevent leakage of information on the tape cartridge, even if the tape cartridge is left
unattended when taken out or is missing, because its data cannot be read without the key.
Also, the tape cartridge can be disposed of without deleting the data.
*1: Advanced Encryption Standard (AES): Encryption system authorized by the National Institute of Standards and
Technology (NIST)
*2: Excludes Ultrium3 or earlier generation data cartridges that do not support the data encryption function.
*3: The data cartridge generations that can be read and written varies depending on the generation of the LTO Ultrium
tape drive that is being used. For details, refer to "A.1.2 Tape Drive Compatibility with Tape Cartridges" in "FUJITSU
Storage ETERNUS LT140 Tape Library User's Guide -Installation & Operation-".
1.2 Features of the Data Encryption Function of LTO Ultrium Tape
Drives
The data encryption function of LTO Ultrium tape drives has the following features:
• The function conforms to the high security requirements specified in FIPS 140-2 (*1).
• A key can be delivered through the host interface and the interface between a library and tape drive.
• The encryption logic is implemented by hardware, which means that encryption has less effect on read-
write performance.
*1: FIPS 140-2 defines the U.S. government's security requirements for cryptographic modules used for data.
