The Federal Data Encryption Standard (DES) [1] is a block product cipher which converts 64-bit blocks of plaintext into 64-bit blocks of cipher text, or vice-versa, under the control of a 56-bit key. There has in the past been considerable controversy over the adequacy of DES key length [2,3,4]. Easily implemented modifications to the DES key schedule (KS) would allow the use of keys longer than 56 bits.
