The quantum key distribution (QKD) Network Cipher Machine integrates the QKD module and the high-speed -encryption PCB board and uses the quantum key to encrypt the network data to protect the data confidentiality and the integrity. It uses the decoy-state BB84 protocol and encryption algorithm which supports SM1 or AES128/192/256. The SJJ1411 model is the first QKD network cipher machine in the field of domestic commercial cryptography, which has been approved by the State Cryptography Administration.
