BATON
BATON is a Type 1 block cipher in use since at least 1995 by the United States government to secure classified information.
While the BATON algorithm itself is secret, the public PKCS#11 standard includes some general information about how it is used. It has a 320-bit key and uses a 128-bit block in most modes, and also supports a 96-bit electronic codebook mode. 160 bits of the key are checksum material. It supports a "shuffle" mode of operation, like the NSA cipher JUNIPER. It may use up to 192 bits as an initialization vector, regardless of the block size.
In response to a Senate question about encrypted video links, NSA said that BATON could be used for encryption at speeds higher than those possible with Skipjack.Usage
BATON is used in a variety of products and standards:
