Embodiment 1
[0082] Embodiment 1 of the present invention proposes a quantum secure data link communication system. The business requirement key used for secure communication is generated by a pair of quantum key generation devices, and is delivered to the system through the key management control server to pass the authentication. Multiple security terminals, the communication terminal can be connected to any business equipment, use the quantum key to encrypt and transmit business data in real time, and can also store the received quantum key for mobile use after the key distribution is completed. System block diagram as image 3 shown.
[0083] The quantum secure data link communication system is mainly for metropolitan area network users, providing quantum key distribution control, quantum key management, key relay, and key output functions, and has the characteristics of high integration.
[0084] The secure communication devices located in the two places in the system are connected t...
