Compute the S-Box (i.e. the ByteSub layer) value for the following input bytes: (a) (29)Base16 (b) (F3)Base16 Recall that in order to do this, you
Compute the S-Box (i.e. the ByteSub layer) value for the following input bytes:
(a) (29)Base16
(b) (F3)Base16
Recall that in order to do this, you should first look up the inverses using table 4.2 to obtain intermediary value B. Next, perform the affine mapping by computing the matrix-vector multiplication and addition mod 2.
Hint: you can verify your results by using S-Box table 4.3 on page 101 of P&P.
