Evaluation of the possibility of using quantum cryptography and the LoRaWAN 2 protocol to establish communication with an unmanned aerial vehicle

Purpose of research . Modern unmanned aerial vehicles face challenges in maintaining reliable communications in the face of radio interference, difficult terrain (mountains, forests), or active electronic countermeasures. One possible solution to this problem is the application of quantum cryptography principles in combination with the latest communication protocols, such as LoRaWAN 2, which help ensure secure and stable data transmission in challenging environments. The Purpose of the esearch is to evaluate the feasibility of using quantum cryptography and the LoRaWAN 2 protocol to establish and maintain continuous, stable communication with an unmanned aerial vehicle. Methods . The research methods are based on concepts from statistical radio engineering theory and ultra-high-frequency radio wave propagation theory. Multicriteria analysis, parametric synthesis, and structural synthesis methods are used. The principles of information transmission from unmanned aerial vehicles are analyzed. A critical assessment of the performance of a UAV using quantum cryptography and the LoRaWAN 2 protocol is conducted. Results . Analytical expressions and comparative characteristics are presented to assess the potential for using quantum cryptography and the LoRaWAN 2 protocol with unmanned aerial vehicles. It is shown that using quantum cryptography, the probability of data interception in a UAV communication channel is approximately 1%, significantly increasing its security compared to RSA-2048. Quantum cryptography improves UAV security and key retrieval with a slight increase in weight, power consumption, and speed. In the coming years, with the development of compact systems, its promising implementation will become the standard for commercial drones. Conclusion . As promising areas of research and application in the field of using unmanned aerial vehicles, the use of quantum cryptography technology and the LoRaWAN 2 protocol should be considered, which contributes to improving the characteristics of UAVs: high range, energy efficiency, security and scalability.
