How Small Can S-boxes Be?
S-boxes are the most popular nonlinear building blocks used in symmetrickey primitives. Both cryptographic properties and implementation cost of an S-box are crucial for a good cipher design, especially for lightweight ones. This paper aims to determine the exact minimum area of optimal 4-bit S-box...
