[Crack Hack] aes_sbox DL : 0: The substitution tables (S-boxes) s_box and inv_s_box are used by the expanded key schedule function key_expansion and the en- and decrypting functions cipher and inv_cipher to directly substitute a byte (element of GF(28)) by another byte of the same finite field. In any speed optimized real-world application the substitution tables would definitely be hard coded a priori in a constant but in the scope of this educational paper it seems to be interesting, how the S-boxes can be generated.-The substitution tables (S-boxes) s_box and inv_s_box are used by the expanded key schedule function key_expansion and the en- and decrypting functions cipher and inv_cipher to directly substitute a byte (element of GF(28)) by another byte of the same finite field.

[Crack Hack] aes_inv_sbox DL : 0: The inverse S-box is used in the decrypting function inv_cipher to revert the substitution carried out via the S-box. The corresponding AES-Matlab function declared in Line 1 of Listing 7 takes the Sbox (s_box) as its input and generates the inverse S-box inv_s_box in a single loop . The loop runs through all elements of the S-box, interprets the current S-box element value as an index into the inverse S-box and inserts the values 0 . . . 255 at the appropriate places in the inverse S-box-The inverse S-box is used in the decrypting function inv_cipher to revert the substitution carried out via the S-box.

[Crack Hack] aes_key_expand_128 DL : 0: The key expansion function takes the user supplied 16 bytes long key and utilizes the previously created round constant matrix rcon and the substitution table s_box to generate a 176 byte long key schedule w, which will be used during the en- and decryption processes. The blue arrowed closed loop indicates that the functions rot_word and sub_bytes are called iteratively by the key expansion function.-The key expansion function takes the user supplied 16 bytes long key and utilizes the previously created round constant matrix rcon and the substitution table s_box to generate a 176 byte long key schedule w, which will be used during the en- and decryption processes.

[Crack Hack] aes_cipher_top DL : 0: the first task of the ”main” program aes_demo is a call to aes_init in Line 1. This initialization routine supplies 1 the actual en- and decryption functions (cipher and inv_cipher) with the expanded key schedule w, the substitution tables s_box and inv_s_box, and the polynomial matrices poly_mat and inv_poly_mat. These quantities have to be generated only once and can be used by any subsequent en- or decipher call.
