Distribusi Difference dari S-Box Berbasis Fungsi Balikan Pada GF(28)
Abstract: Substitution-box
(s-box) is a basic component of block cipher which performs a substitution. Two
powerful cryptanalysis techniques applied to block ciphers are linear
cryptanalysis and differential cryptanalysis. The resistance against
differential cryptanalysis can be achieved by eliminating high-probability
differential trails. We should choose an s-box where the maximum difference
propagation probability is as small as possible to eliminating high-probability
differential trails. Nyberg proposed a method to construct the s-box by using
the inverse mapping on a finite field then implements affine transformations on
. In this study, we generate 47.104 s-box according to Nyberg. The experimental
results showed that s-boxes have the maximum difference propagation probability
with the same frequency.
