[page 83 (continued)] 34 differential and linear cryptanalysis for most of its life, the prime concern with des has been its vulnerability to brute-force attack because of its relatively short (56 bits) key length. Differential and linear cryptanalysis multi-round ciphers such as des are clearly very difficult to crack one property they have is that even if one has some corresponding plaintext and ciphertext, it is not at all easy to determine what key has been used.
