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.
