This paper presents a generic method for the synthesis of nonlinear inverse operations expanded matrix cryptographic transformation, built on the basis of specific logical functions extended cryptographic transformation n- digit matrix. With specific examples of finding a mathematical model the inverse operation of cryptographic transformation confirmed the correctness of the developed method for the synthesis of non-linear operations.
