Abstract: As an important link of ensuring the safety of trains in the subway industry and the safety of life and property of passengers, information security has always been the focus of the industry and academia. In order to meet the information security requirements of communication in different scenes in the daily production and operation of the subway, and improve the subway quantum security ecosystem, the information security problems of communication in the process of subway train operation are studied. The microwave quantum communication scheme based on free space channel is analyzed. Through the performance simulation of the protocol, the security key rate and transmission distance of the microwave scheme are calculated. Finally, the method to improve the security key rate is given, which lays the foundation for the next experimental application research.
