Abstract
We present the results of our search to find the performance of the various spectrum based cost functions and the effect of varying its parameter in the design of strong S-Boxes. It is conjectured that good S-Boxes can be obtained, if the search is made with the parameters R > 3.5 and X < 2n/2 and a more consistent performance can be expected if we use non-linearity spread as the annealing function.
