Affine-Power S-Boxes over Galois Fields with Area-Optimized Logic Implementations

2015 · RIT Scholar Works (Rochester Institute of Technology)

Abstract. Cryptographic S-boxes are fundamental in key-iterated sub-stitution permutation network (SPN) designs for block ciphers. As a natural way for realizing Shannon’s confusion and diffusion properties in cryptographic primitives through nonlinear and linear behavior, re-spectively, …
