NIST received several thoughtful public comments on the draft NIST Special
Publication 800-38B specifying RMAC as a recommended MAC algorithm for use
with either AES and Triple DES. In response to the comments, NIST has
posted a consultation paper at http://csrc.nist.gov/CryptoToolkit/modes/,
with a link to the paper under the heading "NIST Recommendation for
Modes." The paper summarizes the technical issues underlying the selection
of a block cipher based MAC and proposes to refocus the RMAC specification
to its underlying EMAC construction.
Further comments on the draft SP 800-38B and the consultation paper may be
submitted to [EMAIL PROTECTED] until May 5, 2003.
