Description: 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

Description: 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

Description: 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

Description: 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.
