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
