NIST announces the public comment release of SP 800-56C Rev. 1 and SP 800-56A Rev. 3. SP 800-56C has been revised to include all key derivation methods currently included in SP 800-56A and SP 800-56B, Recommendation for Pair-Wise Key-Establishment Schemes Using Integer Factorization Cryptography, in addition to the two-step key-derivation procedure currently specified in SP 800-56C. Note the change of title for SP 800-56C that reflects the inclusion of the additional key-derivation methods. SP 800-56C Revision 1 also includes the use of KMAC128 and KMAC256 as key-derivation primitives for the one-step key-derivation method.
