Forward Cipher Function

Abbreviation(s) and Synonym(s):

None

Definition(s):

  One of the two functions of the block cipher algorithm that is selected by the cryptographic key.
Source(s):
NIST SP 800-38A under Forward Cipher Function (Forward Cipher Operation)

  A permutation on blocks that is determined by the choice of a key for a given block cipher.
Source(s):
NIST SP 800-38B
NIST SP 800-38D

  One of the two functions of the block cipher algorithm that is determined by the choice of a cryptographic key.
Source(s):
NIST SP 800-38C

  The permutation of blocks that is determined by the choice of a block cipher and a key.
Source(s):
NIST SP 800-38F under forward transformation

  One of the two functions of the block cipher algorithm that is determined by the choice of a cryptographic key. The term “forward cipher operation” is used for TDEA, while the term “forward transformation” is used for DEA.
