Key derivation

Definition(s):

  The process that derives keying material from a key.
Source(s):
NIST SP 800-108

  1. A process by which one or more keys are derived from a shared secret and other information during a key agreement transaction.
Source(s):
NIST SP 800-133 [Superseded]

  2. A process that derives new keying material from a key (i.e., a key-derivation key) that is currently available.
Source(s):
NIST SP 800-133 [Superseded]

  The process of deriving a key in a non-reversible manner from shared information, some of which is secret.
Source(s):
NIST SP 800-152

  A process that derives keying material from a key or a shared secret.
Source(s):
NIST SP 800-56C [Superseded]

  The process by which one or more keys are derived from either a pre-shared key or a shared secret (from a key-agreement scheme), along with other information.
Source(s):
NIST SP 800-57 Part 1 Rev. 4 [Superseded]

  As used in this Recommendation, a method of deriving keying material from a pre-shared key and possibly other information. See NIST SP 800-108.
Source(s):
NIST SP 800-57 Part 2 Rev.1

  A process by which one or more keys are derived from a shared secret and other information during a key-agreement transaction.
Source(s):
NIST SP 800-133 Rev.1 [Superseded]
NIST SP 800-133 Rev. 2

  A process that derives new keying material from a key (i.e., a key-derivation key) that is currently available.
Source(s):
NIST SP 800-133 Rev.1 [Superseded]
NIST SP 800-133 Rev. 2

  The process by which keying material is derived from either a pre-shared key or a shared secret produced during a key-agreement scheme along with other information.
Source(s):
NIST SP 800-175B Rev. 1

  The process by which keying material is derived from either a pre-shared key or a shared secret (from a key-agreement scheme), along with other information.
Source(s):
NIST SP 800-57 Part 1 Rev. 5

  A function in the lifecycle of keying material; the process by which one or more keys are derived from either a pre-shared key, or a shared secret and other information.
