Block Cipher Algorithm

Definition(s):

  A family of functions and their inverse functions that is parameterized by cryptographic keys; the functions map bit strings of a fixed length to bit strings of the same length.

NIST SP 800-175B Rev. 1 under Block cipher algorithm

  A family of functions and their inverses that is parameterized by cryptographic keys; the functions map bit strings of a fixed length to bit strings of the same length.
Source(s):
NIST SP 800-38C

  A family of functions and their inverses that is parameterized by a cryptographic key; the function maps bit strings of a fixed length to bit strings of the same length.
Source(s):
NIST SP 800-67 Rev. 2
NIST SP 800-67 Rev. 1 [Superseded]

  A symmetric-key cryptographic algorithm that transforms one block of information at a time using a cryptographic key. For a block cipher algorithm, the length of the input block is the same as the length of the output block.
