Hi Eric and Joe and TLS WG members,

I have submitted an updated version of raft-mcgrew-tls-aes-ccm.  There  
are only minor editorial changes since the initial version, which was  
presented in Maastricht, so there is no need to present an update in  

I would like to as the WG to take on this work as a standards track  
item.  It would need to be coordinated with draft-mcgrew-tls-aes-ccm- 
ecc, which Matt will be presenting in Prague.  Here is a quick rundown  
on the similarities and differences.  Both drafts use AES-CCM for TLS  
1.2, and they use it in the same way.  They differ only in key  
management and authentication.  draft-mcgrew-tls-aes-ccm defines PSK  
and RSA ciphersuites.  draft-mcgrew-tls-aes-ccm-ecc defines ECC  
ciphersuites.  Both drafts define the same AEAD algorithms;  
eventually, this copy-by-value should be replaced with a copy-by- 

Comments welcome.

> Abstract:
> This memo describes the use of the Advanced Encryption Standard (AES)
