NIST announces the public comment release of SP 800-56A Rev. 3 and SP 800-56C Rev. 1. SP 800-56A specifies key-establishment schemes based on the discrete logarithm problem over finite fields and elliptic curves, including several variations of Diffie-Hellman (DH) and Menezes-Qu-Vanstone(MQV) key establishment schemes. Revision 3 approves the use of specific safe-prime groups of domain parameters for finite field DH and MQV schemes and requires the use of specific commonly used elliptic curves. In addition, all methods used for key derivation have been moved to SP 800-56C.
