Substitution boxes (s-boxes) providing the nonlinearity property are fundamental
components of modern encryption systems. The security of these systems directly depends …

Abstract A Feistel Network (FN) based block cipher relies on a Substitution Box (S-Box) for
achieving the non-linearity. S-Box is carefully designed to achieve optimal cryptographic …

In a digital universe of widespread technological gadgets, cryptographic algorithms and
protocols remain integral to human beings, directly or indirectly. Followed by the recent …

The security of encryption systems directly depends on the quality of the s-boxes, providing
a high level of resistance to sophisticated attack methods. Although there is no perfect …
