Generation of Dynamical S-Boxes for Block Ciphers via Extended Logistic Map

<div>Fixed points stability where an asterisk and a circle denote repulsive and attracting fixed points, respectively. The extended logistic map have both repulsive fixed points at <i>α</i> ∈ [−2/2<sup>8</sup> ≈ −0.0078, −1/2<sup>8</sup> ≈ −0.0039] ∪ [3/2<sup>8</sup> ≈ 0.0117, 4/2<sup>8</sup> ≈ 0.0156].</div>
