WebWe introduce a new method for cryptanalysis of DES cipher, which is essentially a known-plaintext attack. As a result, it is possible to break 8-round DES cipher with 22' known-plaintexts and 16-round DES cipher with 2" known-plaintexts, respectively. Moreover, this method is applicable to an only-ciphertext attack in certain situations. 7世纪日本改革
