A Novel Construction of Efficient Substitution-Boxes Using Cubic Fractional Transformation

Entropy, 2019
A symmetric block cipher employing a substitution–permutation duo is an effective technique for the provision of information security. For substitution, modern block ciphers use one or more substitution boxes (S-Boxes).
