Claudia Peerez Ruisanchez · International Journal of Soft Computing Mathematics and Control · 2015
In this paper is proposed a new algorithm to construct S-Boxes over GF(28) with Branch Number value at least 3.This is an important property that guarantees a high diusion in the S-Box [12].Also are introduced some defnition and properties that show the be-havior of S-Boxes under the composition with affine functions.Finally is presented a comparision between this algorithm and the method pro-posed by Tavares [12].
