cipher feedback [¦sī·fər ¦fēd‚bak]

(communications)

An implementation of ciphertext autokey cipher in which the leftmostnbits of the data encryption standard (DES) output are added by the EXCLUSIVE OR operation toNbits of plaintext to produceNbits of ciphertext (whereNis the number of bits enciphered at one time), and theseNbits of ciphertext are fed back into the algorithm by first shifting the current DES inputNbits to the left, and then appending theNbits of ciphertext to the right-hand side of the shifted input to produce a new DES input used for the next iteration of the algorithm.
