Summary:
|
Based on ITU-T Recommendation Y.3800, many study items are successfully developed and developing so far. However, in case that mobile objects (i.e., autonomous car, mobile phone, etc.) are to be supplied QKD service, there is a difficulty to establish and maintain a quantum channel stably with them. KSA-keys are not able to be supported on this situation.
For the purpose of delivery of KSA-keys generated from QKD network into the mobile objects, the keys can be delivered through user network using PKI technology (especially key exchange protocol) with PQC algorithm.
Therefore, the integration of QKD network with non-quantum cryptography will enable the QKD network/service providers, bringing its cryptography service to a much wider range of business opportunity.
For this purpose, the relationship between QKDN and E2E cryptography service will be introduced. Then, relative examples for the integration of QKD network with non-quantum cryptography will be described. Finally, based on the analysis of the detailed attributes of examples, implications in terms of further study issue will be identified.
