Summary:
|
It is challenging to integrate a quantum key distribution network (QKDN) and a user network to support end-to-end modern cryptography services to users including mobile objects (i.e., autonomous car, mobile phone, etc.). [b-ITU-T Supplement 79 to Y.3800-series] addresses this issue and describes several use cases to deliver KSA-keys generated from QKDNs to the user applications by means of modern cryptography (e.g., PKI technology) with PQC algorithms. It also identifies various issues to be addressed for standardization. Technical implications from the three end-to-end use cases identified are related to control and management, and QoS aspects. Especially, Y.3828 addresses QoS assurance specific aspects in terms of reference models and requirements.
This draft Recommendation specifies functional architecture, associated capabilities, reference points, and an operational procedure of QoS assurance for integrated QKDN and UNemc based on the defined reference models and requirements in Y.3828.
