In this paper formulated the conditions of nondegeneracy of nonlinear operations expanded matrix cryptographic transformation n-th digit capacity, which contain incomplete functions of expanded matrix cryptographic transformation (EMCT). The example shows the application of the conditions obtained and correctness of the method of constructing an expanded matrix reverse operation of cryptographic transformation of the 4th digit capacity.
nonlinear operation EMCT, incomplete function EMCT, additions of functions EMCT
