WebbNIST has defined some key derivation functions, which can be used to derive new key using one of NIST recommended MAC algorithms, AES-CMAC or HMAC. These functions can meet your needs. The functions are defined in NIST SP 800-108: Recommendation for Key DerivationUsing Pseudorandom Functions. In cryptography, a key derivation function (KDF) is a cryptographic algorithm that derives one or more secret keys from a secret value such as a master key, a password, or a passphrase using a pseudorandom function (which typically uses a cryptographic hash function or block cipher). KDFs can be used to … Visa mer The first deliberately slow (key stretching) password-based key derivation function was called "crypt" (or "crypt(3)" after its man page), and was invented by Robert Morris in 1978. It would encrypt a constant (zero), using the first … Visa mer Despite their original use for key derivation, KDFs are possibly better known for their use in password hashing (password verification by hash comparison), as used by the Visa mer The original use for a KDF is key derivation, the generation of keys from secret passwords or passphrases.
