Abstract— An experimental prototype of a software and hardware complex for secure data transmission in 4G/5G mobile networks is developed using quantum key distribution (QKD) technologies. The structure and fundamental operational principles are outlined, along with details of both hardware and software components. The developed prototype is a fully functional system capable of secure text, audio, and video messaging. Encased in a hermetically sealed ruggedized case, the system can be deployed both indoors and outdoors.
