Summary:
|
This Recommendation specifies key generation control protocols for Cq interfaces for quantum key distribution networks. It specifies signalling procedures, messages and parameters at Cq interfaces. The Cq reference point is defined in [ITU-T Y.3802] for the QKDN controller to communicate control information with the QKD module.
