Abstract: In this paper, we present a matrix approach based on the rule 90 cellular automata, and a fractional linear transformation over Galois field $$GF(2^8)$$GF(28), to implement a strong substitution box (S-box). To make the assessment… read more here.

Abstract: In the realm of information security, the nonlinearity of an S-Box is a pivotal attribute for ensuring its effectiveness. S-Boxes randomly generated with chaotic maps, however, often exhibit insufficient nonlinearity. To construct a robust S-Box… read more here.
