FYI.

A side question: how many people on this mail list are *not* also on  
the IETF security area advisory group mail list?   If the lists have  
many people in common, then I won't bother forwarding in the future.

> Second draft of 800-56C: Recommendation for Key Derivation through  
> Extraction-then-Expansion is posted for public comments. The initial

> This Recommendation specifies techniques for the derivation of  
> keying material from a shared secret established during a key  
> establishment scheme defined in NIST Special Publications 800-56A or  
> 800-56B through an extraction-then-expansion procedure. NIST is in  
> the process of modifying SP 800-56A and SP 800-56B to include the  
> extraction-then-expansion key derivation procedure specified in this
