stds-802-16: NIST Pulbished AES-CCM draft
NIST has published CCM as a draft standard and is calling for comment.
This is the mode I am proposing to be used in an 802.16 enhanced
security mechanism. It is also the mode currently adopted by 802.11i and
is being proposed for 802.1ae.

NIST has recently developed the draft Special Publication 800-38C,
"Recommendation for Block Cipher Modes of Operation: the CCM
Mode for Authentication and Confidentiality," which is now available
for review from the draft publications page on the NIST web site,
http://csrc.nist.gov/publications/drafts.html.
The draft specifies the CCM mode, authored by Whiting, Housley,
and Ferguson, with the AES algorithm as the underlying block cipher,
but not Triple DES. CCM combines the CTR mode for confidentiality
with the CBC-MAC technique for authentication and data integrity.
CCM was designed for use in a packet environment; in particular,
the specification of CCM is intended to be compatible with the use
of CCM within the draft IEEE 802.11i standard.
Further information on the development of block cipher modes of
operation is available at the modes home page, http://nist.gov/modes/.
NIST welcomes public comments on the draft until October 20, 2003;
comments may be sent to EncryptionModes@nist.gov.
