To implement the AES decryption, one should undo all operation one-by-one doing the inverse: you could, therefore, rewrite the table generator algorithm following this logic and then writing the corresponding decryption function where the round structure is inversed. What are the important steps to modify an WB encryption project into a WB decryption project? Both set are generated using, of course, the same secret AES key. you need two different sets of tables to implement the encryption and the decryption algorithm.
Encryption table & decryption table are generated separately, using one same key (e.g., 16 byte key for AES128)? Correct? which means there are two table generation algorithms (and hence two separate lookup tables) - one encryption, one for decryption.
