Security Models and Methods of Socio-Cyberphysical Systems

The subject of the study is the processes of building an aerial mobile communication network of a socio-cybephysical system. The goal is to develop recommendations for building a hybrid wireless mobile communication network SCPS - a system that is the basis of its system security and functions effectively in conditions of interference. The development is based on the technology of ultra-wideband signals that circulate in control and communication channels. The task is to ensure the stable and safe operation of the air wireless mobile communication network of the SCPS system. Methods used: methods of analytical modeling and time positional-pulse encoding. The following results were obtained. A mathematical model was developed that made it possible to determine the ratio of working and security elements of the system at the early stages of its design. Recommendations for building a wireless mobile communication system have been developed. It is shown that in order to obtain high noise immunity of control and communication channels and protect information from interception, ultra - wideband communication technology should be used, which allows providing large volumes and speeds of information transmission between nodes of the mobile network of the SCPS system in conditions of interference. Conclusions. The developed mathematical model proved the existence of an optimal strategy for the behavior of the external environment and an optimal primary structure of the SCPS system, the use of which allows increasing its stability by more than one and a half times. The use of ultra - wideband technologies in the control and communication channels of the SCPS system wireless network made it possible to improve the quality of wireless network channels and increase the number of communication channels without UAV control interception, information and mutual interference. At the same time, by reducing the levels of electromagnetic radiation of information and control signals, which does not exceed the noise level in the operating frequency range, it made it possible to hide the very fact of temporary establishment of communication channels in the wireless mobile network of the SCPS system.
