Abstract
In cryptography, S-box is a basic component of symmetric key algorithms which performs nonlinear substitution. S-boxes need to be highly nonlinear, so that the cipher can resist linear cryptanalysis.
The main criteria for cryptographically strong (n × n) S-box are:
• High non linearity;
• High algebraic degree;
• Balanced structure;
• Good auto correlation properties.
Our task was to give some suggestions for finding an effective metric used for generation bijective optimal S-Box. Because of the given problem’s complexity, our group considered different approaches and we gave a few suggestions for problem solving.
