Experiment 2 - DES Encryption
During the DES decryption process, what is the purpose of the 'Inverse Initial Permutation'?
What is the purpose of the 'S-Box' substitution in DES decryption?
After completing the 16 rounds of DES decryption, what is the next step?
As a change in one bit of the plaintext or one bit of the key should produce a change in many bits of theciphertext. This is known as the avalanche effect.
The number of unique substitution boxes in DES after the 48 bit XOR operation are
Which one is the Heart of Data Encryption Standard (DES)?
