Dynamic S-box construction via rotationally nonsingular binary matrix families for symmetric-key block ciphers

Substitution boxes are fundamental nonlinear components of symmetric-key ciphers, and dynamic S-box generation provides a means of diversifying the nonlinear layer during operation. However, many existing approaches focus on constructing or optimizing individual S-boxes and do not provide a systematic mechanism for...

An AES-inspired Construction of a Cryptographically Strong 8×8 S-box Using Modified Algebraic and Affine Parameters

Substitution boxes (S-boxes) are essential nonlinear components in symmetric-key block ciphers and play a central role in providing resistance against linear and differential cryptanalytic attacks. In this paper, a new 8×8 S-box is proposed based on an AES-inspired inverse-affine construction. Unlike the standard AES...
