BATON is a Type 1 block cipher, used by the United States government to secure all types of classified information.

BATON has a 128-bit block size and a 320-bit key. 160 bits of the key are checksum material; they do not affect the security of the algorithm itself but rather prevent unauthorized keys from being loaded if a BATON device ends up in the hands of an adversary. BATON is fast: on the Advanced INFOSEC Machine (AIM) chip, it encrypts data at 129% of the clock rate, as opposed to 76% for DES, 25% for Triple DES, and 4% for SAVILLE. Its speed and parallelizability were major factors in its selection.

The Sierra II documentation suggests that BATON may be related to MEDLEY.

Usage

BATON is used in a variety of products and standards:
*APCO Project 25 (Public standard for land mobile radio) (Algorithm IDs 01 and 41)
*PKCS#11 (Public standard for encryption tokens)
*CDSA/CSSM (Another public standard)
*HAIPE-IS (NSA's version of IPsec)
*FNBDT (Advanced flexible voice security protocol)

*Thales Datacryptor 2000 (a British network-encryption box)
*SecNet-11 (a crypto-secure 802.11b PC Card, based on the Sierra chip)
*Fortezza Plus (a PC Card product, used in the STE)
*SafeXcel-3340 (a HAIPIS network-encryption box)
*Numerous embeddable encryption modules: AIM, CYPRIS, MYK-85, Sierra (microchip), etc.
