WebThe most common form of key whitening is xor-encrypt-xor -- using a simple XOR before the first round and after the last round of encryption . The first block cipher to use a form of key whitening is DES-X, which simply uses two extra 64-bit keys for whitening, beyond the normal 56-bit key of DES. This is intended to increase the complexity of ...
