Key wrapping

Abbreviation(s) and Synonym(s):

None

Definition(s):

  A method of protecting keying material (along with associated integrity information) that provides both confidentiality and integrity protection when using a symmetric-key algorithm.
Source(s):
NIST SP 800-56B Rev. 1

  A method of encrypting and decrypting keys and (possibly) associated data using a symmetric key; both confidentiality and integrity protection are provided.
Source(s):
NIST SP 800-133

  A method of cryptographically protecting keys using a symmetric key that provides both confidentiality and integrity protection.
Source(s):
NIST SP 800-152
NIST SP 800-57 Part 1 Rev. 4

  A method of encrypting keys (along with associated integrity information) that provides both confidentiality and integrity protection using a symmetric key.
Source(s):
NIST SP 800-57 Part 1 Rev. 3 [Superseded]

  Encrypting a symmetric key using another symmetric key (the key encrypting key). A key used for key wrapping is known as a key encrypting key.
