Quantum Key Distribution Node Apparatus and Method for Quantum Key Distribution thereof

摘要

A quantum key distribution node apparatus and a quantum key distribution method in the apparatus are disclosed. Quantum key distribution node device according to an embodiment of the present invention, a quantum key distribution unit for generating a quantum key and a quantum key ID, the quantum key and quantum key ID generated by the quantum key distribution unit as a transmission quantum key and a reception quantum key As the master key is requested along with the ID of another encryption device from the quantum key synchronization management unit and the connected encryption device that share the quantum key distribution node device with the quantum key distribution node device as well as the distribution storage, the randomly generated master key and In addition to delivering the master key ID to the cryptographic device, the packet containing the master key, master key ID and quantum key ID encrypted with the transmission quantum key shared with other quantum key distribution node devices connected to other cryptographic devices is transmitted to other quantum key distribution nodes. It may include a quantum key integrator to transmit to the device.
