Abstract: The quantum secure communication technology is theoretically unbreakable; and has stronger security protection capabilities than traditional encryption methods. This paper proposes an applied design scheme for quantum secure communication in automatic fare collection (AFC) systems of urban rail transit on the basis of the actual requirements of the AFC system, and in view of the architecture and network transmission scheme of the AFC system. The quantum security equipment is deployed at the clearing center, the line center, and various stations; and the quantum secure communication technology is used to encrypt and transmit the sensitive information of the AFC system. Thus, the data transmission security of the core service system is ensured, and the security protection capability of the AFC system is improved. The proposed design scheme has the characteristics of high security, low impact on AFC system, low implementation difficulty, and strong replicability; and can provide reference for the application of the quantum secure communication technology in various AFC systems of urban rail transit.
