Quantum Key Management Machine is a highly integrated product, which has functions of quantum key distribution control, key management, key relay and optical switch controlling.

The Quantum Key Management Machine cooperates with the key generation control of the quantum key management service system, which can control the optical switching and the quantum key distribution process under its jurisdiction. It also cooperates with the relay routing of the quantum key management service system, which obtains the key relay routing table and completes the key relay process to achieve quantum key distribution networking.

The Quantum Key Management Machine adopts the "XOR relay" security enhancement technique to achieve the "one-time pad" encryption storage and caching of key, which solves the problem of key leakage caused by network intrusion. The products are 19-inch 4U standard rackable enclosure, and suitable for the engine room environment.
