The block cipher DES has a few specific keys termed "weak keys" and "semi-weak keys". These are keys that cause the encryption mode of DES to act identically to the decryption mode of DES (albeit potentially that of a different key). In operation, the secret 56-bit key is broken up into 16 subkeys according to the DES key schedule; one subkey is used in each of the sixteen DES rounds. DES weak keys produce sixteen identical … WebErrata to: K. Markantonakis and K. Mayes (eds.), Secure Smart Embedded Devices, Platforms and Applications, DOI 10.1007/978-1-4614-7915-4.
