Some Analysis of S-box based on Residue of Prime Number

In this article, we analyze substitution box (S-box) based on residue of prime number for different analysis such as graphical and analytical strict avalanche criterion (SAC), bit independent criterion (BIC), differential approximation probability (DP), linear approximation probability (LP) and nonlinearity. With the help of these results we determine the algebraic and statistical encryption strength and weakness of this S-box.
