Titanium S-Boxes: A New Family of 4-bit Optimal S-Boxes for Feistel-Based Lightweight Block Ciphers

Substitution boxes (S-boxes) are the main nonlinear components in lightweight block ciphers (LBCs), including Feistel-based designs. Whereas existing S-boxes achieve optimal resistance to differential attacks (DAs), most remain vulnerable to boomerang (BAs) and algebraic (AAs) attacks, and often their assessment overlo...
