  • Patent number: 12438708
    Abstract: A physical link is split between network devices into a first logical link and a second logical link. The first logical link is designated for communicating user data. The second logical link is designated for exchanging key identifiers (key IDs) only. The second logical link is left open and unencrypted and the key IDs are exchanged over the second logical link. Using the key IDs, quantum keys are acquired, by an agent on each respective network device, from a quantum key distribution network or subsystem. The quantum keys thus acquired are then applied to the physical link between the network devices to thereby transition the physical link between the network devices to a quantum-secure environment and open the first logical link for communicating the user data in the quantum-secure environment.
