Purpose: For information

Body: ITU-T SG13 is pleased to inform you about our progress on Quantum Key Distribution (QKD) topics.
We informed you that SG13 has published 5 Recommendations on QKDN as follows:
-	Recommendation ITU-T Y.3800 “Overview on networks supporting quantum key distribution”;
-	Recommendation ITU-T Y.3801 “Functional requirements for quantum key distribution networks”;   
-	Recommendation ITU-T Y.3802 “Quantum key distribution networks – Functional architecture”; 
-	Recommendation ITU-T Y.3803 “Quantum key distribution networks – Key management”;  
-	Recommendation ITU-T Y.3804 “Quantum key distribution networks - Control and management”.

In the SG13 meeting (Virtual, 1-12 March 2021), Q16/13 has made progress of the following work items.

1. The item consented after the December 2020 SG13 meeting
The corrigendum to ITU-T Y.3802 was consented. 

Corrigendum 1, Recommendation ITU-T Y.3802 “Quantum key distribution networks - Functional architecture” in TD388/PLEN

Corrigendum 1 to Recommendation ITU-T Y.3802 (2020) removes ‘IT-secure’ from the definition of key management agent (KMA) link.

2. Revised on-going work items

Draft Recommendation ITU-T Y.QKDN_SDNC “Quantum key distribution networks - Software defined networking control” in TD550/WP3 

Recommendation ITU-T Y.QKDN_SDNC specifies the requirements, functional architecture, reference points, hierarchical SDN controller, overall operational procedures of SDN control, and controllable elements for SDN in QKDN and security considerations.

Draft Recommendation ITU-T Y.QKDN_frint “Framework for integration of QKDN and secure network infrastructures” in TD552/WP3 

For quantum key distribution networks (QKDN), Recommendation ITU-T Y.QKDN_frint specifies overview of secure storage networks (SSNs). It also specifies functional requirements, functional architecture model, reference points and phase-in scenarios for SSNs.

Draft Supplement ITU-T Y.supp.QKDN-mla “Quantum key distribution networks - Applications of Machine Learning” in TD556/WP3 

This Supplement studies the applications of machine learning (ML) in quantum key distribution network (QKDN). 

In particular, the scope of this draft Supplement includes: 
-	Overview of ML applications in QKDN;
-	Applications of ML in QKDN at the quantum layer;
-	Applications of ML in QKDN at the key management layer;
-	Applications of ML in QKDN at the control and management layers.

Y.QKDN-SDNC is a candidate for consent and Y.supp.QKDN-mla is a candidate for agreement at the July 2021 SG13 RGM.

3. Conclusion

SG13 will study the network aspects of QKD. Q16/13 looks forward to close cooperation with ITU-T SG2, SG11, SG15, SG17, ETSI ISG-QKD, ISO/IEC JTC1/SC27, AG4, IETF/IRTF, and relevant groups for future standardization on QKD networks.
