Question 5

In the DES algorithm, how many cycles of 48-bit subkeys are used?

Accepted Answer

56 bit key encryption (16 cycles of 48 bit subkeys)

Answer

The Data Encryption Standard (DES) algorithm uses a 56-bit key for encryption, although it takes a 64-bit input (8 bits are parity bits). During the encryption process, DES performs 16 rounds (cycles), and in each round, a unique 48-bit subkey is derived from the original 56-bit key and used to encrypt the data.
