The substitution box (S-Box) is a critical component in symmetric cipher algorithms. In this
paper, we choose the Hindmarsh-Rose system to generate chaotic S-Boxes. We propose …

In block ciphers, the nonlinear components, also known as substitution boxes (S-boxes), are
used with the purpose to induce confusion in cryptosystems. For the last decade, most of the …
