Public review of SP 800-56C

[ebarker@nist.gov]

The second draft of 800-56C: Recommendation for Key Derivation through Extraction-then-Expansion is posted for public comments. The initial draft was released in September 2010. This second version incorporates resolutions to the comments received during the first comment period.

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 draft Recommendation (800-56C). You can find the second draft of NIST SP 800-56C at http://csrc.nist.gov/publications/PubsDrafts.html#SP-800-56-C.
