Abstract

Task statement: development of signal-code structures and algorithms for their application that have the ability to provide information secrecy on channels and control paths for globally moving objects, such as unmanned transport systems, robotic complexes and platforms, as well as other autonomous systems. At the same time, such globally moving autonomous objects are considered by the Russian Ministry of Transport and its federal agencies Rosmorrechflot, Rosaviation, Roszheldor and Rosavtodor as objects of critical information infrastructure that require protection and measures to prevent unauthorized access to their management and to the data they transmit and receive. The purpose of the work: to ensure information secrecy of control signals of autonomous systems on the network of highways and railways, inland waterways of Russia and in marine areas. Methods used: technologies of spectrum expansion by direct sequence method, spectrum expansion by linear frequency modulation method, as well as the mode of tuning operating frequencies according to a pseudorandom law, technologies of cognitive radio systems and software-defined radio, methods of single-band modulation, amplitude and frequency telegraphy, algorithms for the functioning of an energy detector. The main results of the study include the proposed approach to the implementation of a new class of radio line in the decameter wavelength range, using the transmission of messages by the method of parallel bitwise emission of ultra-narrowband signals. At the same time, the active frequencies are assigned to the information units "1" of the control commands, and the passive, non–radiated frequencies are assigned to the information zeros. The practical significance of the proposed results consists in considering these types of signal-code structures from the standpoint of information secrecy. Without knowing the pseudorandom sequence of operating frequencies involved in the message, which is relevant for the radio link, it is not possible to determine on which passive frequencies the information zeros "0" are transmitted. Therefore, the control command will not be recognized by an outside observer. This can ensure complete information secrecy of its transmission to an autonomous system in the face of attempts to gain unauthorized access to it along the route.

Key words
