Key-derivation key

Abbreviation(s) and Synonym(s):

Definition(s):

  A key used as an input to a key derivation function to derive other keys.
Source(s):
NIST SP 800-107 Rev. 1 under Key Derivation Key
NIST SP 800-108 under Key derivation key

  A key used as an input to a key-derivation method to derive other keys. See [NIST SP 800-108].
Source(s):
NIST SP 800-133 [Superseded]

  A key that is used as an input to a key derivation function or key expansion function to derive other keys.
Source(s):
NIST SP 800-135 Rev. 1 under Key derivation key

  A key that is used as input to the key expansion step to derive other keys. In this Recommendation, the key derivation key is obtained by performing randomness extraction on a shared secret.
