Cryptologia, 2016 In this article, the authors present an efficient S-box generator respecting all criteria and more. Coppersmith’s design criteria served as a basis, but were strengthened for better resistance to linear cryptanalysis. While other researchers have already proposed S-box generators for DES satisfying either non-linearity or good diffusion, our generator ...

S-box, SET, Match: A Toolbox for S-box Analysis [PDF]
, 2014 Boolean functions and substitution boxes (S-boxes) represent the only nonlinear part in many algorithms and therefore play the crucial role in their security. Despite the fact that some algorithms today reuse theoretically secure and carefully constructed S-boxes, there is a clear need for a tool that can analyze security properties of S-boxes and ...
