Description: The article solves the practical task of constructing a digital system for information transmission and displaying in the form of multi-digit numbers with the protection of the numbers of each digit from unauthorized access and errors. Their numbers are in binary-decimal form and are encoded with 4 bits. The numbers after the transmission are displayed on the indicators. The simplicity of the proposed algorithms allows them to be implemented on one PLD chip. This ensures a sufficient level of reliability and performance of the device at its insignificant cost. The secrecy of the transmitted multi-bit numbers is achieved separately for each digit number using a special substitution cipher, which, in each of ten binary-decimal digits, correlates with another binary-decimal digit selected randomly. As a result, the cipher for a single digit of a multivalued number represents a randomly taken permutation of 10 binary-decimal digits. These ciphers can easily be changed if necessary, which ensures their high stability. In addition to the cipher in the form of substitutions in each level, in the multi-bit number, there are also permutations of discharges, which greatly raises the reliability of the cipher as a whole. Errors in the transmission of binary-decimal digits in encrypted form are detected using an equilibrium code and the presence of 6 forbidden combinations for each digit being transmitted. The same keys have the form of permutations of 10 digits, and therefore they have redundancy, which can be used to raise their noise immunity in storage and transmission. Therefore, in general, the system for transmitting and displaying information being developed is protected from both unauthorized access and errors.


Keywords: information transmission system, unauthorized access, permutations, encryption tables, noise immunity, equilibrium code
