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 EncryptionModes at nist.gov until May 5, 2003.
