    “I have no words to express how AMAZING Khalid is! I had an issue with my app and he immediately communicated what was the issue and took great and quick care of it. In addition, since I'm not a technical person, Khalid patiently worked with me so I can understand the process. The quality and professionalism of his work is great and I highly recommend him and definitely hire again.”

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.
