Abstract :
S-boxes are a core component of a cryptographically strong (secret-key) cipher. Mathematically, an n×m S-box is a nonlinear mapping from Vn to Vm, where Vn and V m represent the vector spaces of n and m tuples of elements from GF(2) respectively. The significance of research into S-boxes is indicated by the large number of papers published by researchers from around the world over the past decade
