In the paper considers the traditional way of describing S-blocks through a set of component Boolean functions.non-binary functions were used to represent s-blocks compactly and formalize the method of generating them. Some results of computational search for S-blocks were presented using the proposed approach, where the generated S-blocks have improved properties based on non-linearity and autocorrelation indicators.
