In order to support QKD service to mobile objects (i.e., autonomous car, mobile phone, etc.), it is challenging to establish and maintain a quantum channel stably with them and supporting KSA-keys. Such challenge calls for a solution to integrate the QKDN and user networks supporting modern cryptography services. Y.3826 addresses these challenges and specifies several architectural models, requirements, and a framework architecture for the integration. This draft Recommendation specifies a functional architecture for integration of QKDN and UNemc. It defines a functional architecture, associated functions, reference points and some example operational procedures.
