We propose a regular method of synthesis of optimal substitution cryptographic constructions — S-boxes, with a maximum distance of nonlinearity, and other cryptographic practically attractive properties. The presented method based on the m–shift operators, permutations, cyclic time shift, cyclic frequency shift.
