MODEL OF A COMBINED SPECIAL PURPOSE COMBAT CONTROL SYSTEM

Тopicality. The rapid advancement of computing technology, mobile and Internet technologies, and the digital economy, hybridity and synergy, as well as the development of post-quantum cryptography (particularly the advent of full-scale quantum computers), impose increasingly stringent requirements on the design principles of specialized security mechanisms in contemporary special purpose systems. The conduct of hybrid warfare necessitates modifications not only to the architectural principles of special communication systems (SCS) and systems for delivering combat commands and signals to operational units, but also requires the development of fundamentally novel approaches for command formation and transmission utilizing both dedicated SCS equipment and open commercial systems based on Internet technologies and modern wireless data transmission protocols. Objective. In this article, the authors propose a structural scheme of the advanced combat command and control system of the Armed Forces of Ukraine, which uses both the special communication system in service and open commercial cyberspace systems, with each message being divided into separate components transmitted through all channels, with open channels using digital steganography and/or lossy cryptography methods. Results. At the same time, the interception of individual components in each channel will not allow the adversary to obtain the source text. The final recipient receives a combat command/signal on the basis of a majority selection from all channels, for all parts of the message. This approach makes it possible, in the context of the economic crisis, to ensure the fulfilment of tasks in a timely manner in the face of modern countermeasures (suppression, partial or complete destruction) to the combat control system through the use of cyberspace infrastructure (synthesis of modern technologies of computer systems and networks, Internet technologies, and mobile communication technologies). Conclusions. The presented mathematical component of the assessment of the reliability and probability of delivery of relevant commands/signals allows the proposed model to be modelled with due regard for various interventions in the special-purpose system, both external and internal.
