Announcement
This document specifies families of key derivation functions for deriving additional keys from existing cryptographic keys.
This revision specifies key derivation functions using Keccak-based message authentication codes (KMAC) in addition to key derivation functions using keyed-hash message authentication codes (HMAC) and cipher-based message authentication codes (CMAC).
NOTE: A call for patent claims is included on page iii of this draft. For additional information, see the Information Technology Laboratory (ITL) Patent Policy--Inclusion of Patents in ITL Publications.
This Recommendation specifies techniques for the derivation of additional keying material from a secret key—either established through a key establishment scheme or shared through some other manner—using pseudorandom functions HMAC, CMAC, and KMAC.
