Creation of primitives of strict sustainable coding of minimal complexity

The article presents the results of constructing a complete set of four-digit mathematical models of strict sustainable coding of minimal complexity. The method of synthesis of the algorithm of minimal complexity for construction of operations of strict sustainable coding is investigated and constructed. This method consists in the fact that pair-wise inverting of a certain number of digits is performed and a half of digits of the input information is inverted, while taking into account the limitations that only one digit can be inverted in each pair of transposed digits. To ensure the minimum complexity of technical implementation, dependencies have been obtained for calculating the number of operations of strict sustainable coding
