Draft Recommendation ITU-T Y.3819 (ex Y.QKDN-amc) “Quantum key distribution networks - requirements and architectural model for autonomic management and control” in TD165/PLEN This Recommendation specifies one possible set of functional requirements and a possible architectural model for autonomic management and control (AMC) in QKDNs. 2. The items agreed at the November 2023 SG13 meeting The Technical Report (ex TR.QN-UC), Supplement 80 to ITU-T Y.3800-series (ex Y.supp.QKDN-UC), Supplement 79 to ITU-T Y.3800-series (formerly TR.QKDN-nq) were agreed. Technical Report ITU-T TR.QN-UC “Use cases of quantum networks beyond QKDN” in TD182/PLEN This Technical Report analyses use cases of quantum networks beyond quantum key distribution network (QKDN) in the context of networking technologies as the mandate of ITU-T SG13. The uses cases which are only applied by quantum networks beyond QKDN are collected, investigated and summarized; all use cases are analysed by problem statement, technical considerations along with a short description of each use case. This Technical Report also provides analyses for future applications and potential standardization considerations. Supplement 80 to ITU-T Y.3800-series (ex Y.supp.QKDN-UC) “Use cases of quantum key distribution networks” in TD179/PLEN This Supplement consolidates the QKDN use cases in the context of networking technologies as the mandate of ITU-T SG13. Through a comprehensive analysis, the QKDN uses cases are classified into several classes and this Supplement highlights the competitive advantage of the use cases brought by QKDN and provides suggestions for future standardization efforts in ITU-T SG13. Supplement 79 to ITU-T Y.3800 series (formerly TR.QKDN-nq) “Quantum key distribution networks – Role in end-to-end cryptographic services with non-quantum cryptography” in TD178/PLEN Based on [ITU-T Y.3800], many study items are successfully developed and developing so far. However, in case when mobile objects (i.e., autonomous car, mobile phone, etc.) are to be supplied by quantum key distribution (QKD) service, there is a difficulty to establish and maintain a quantum channel stably with them. Key supply agent-keys (KSA-keys) are not able to be supported in this situation. For the purpose of delivery of KSA-keys generated from quantum key distribution network (QKDN) into the mobile objects, the keys can be delivered through user network using modern cryptography technology (especially key exchange protocol). Therefore, the integration of QKDN with non-quantum cryptography will enable the QKD network and service providers, bringing its cryptography service to a much wider range of business opportunity. For this purpose, the relationship between QKDN and end-to-end (E2E) cryptography service will be introduced. Then, relative use cases for the integration of QKDN with non-quantum cryptography will be described. Finally, based on the analysis of the detailed attributes of use cases, implications in terms of further study issue will be identified. 3. Revised on-going work items after July 2023 SG13 activities Draft Recommendation ITU-T Y.QKDNi_SDNC “Quantum Key Distribution Network Interworking – Software Defined Networking Control” in TD400/WP3 This draft Recommendation specifies the Software Defined Network control for the interworking including the overview of the role of SDN control for the interworking between QKDN providers, the functional entities of SDN control for the interworking, the interfaces of SDN control for the interworking, the functional requirements of SDN control for the interworking, and the security considerations. Draft Recommendation ITU-T Y.QKDNf_fr “Framework of Quantum Key Distribution Network Federation” in TD401/WP3 This draft Recommendation specifies the framework of Quantum Key Distribution Network Federation (QKDNf) including the overview of QKDNf, reference architecture for enabling QKDNf, functional entities of QKDNf, reference points for the QKDNf, functional requirements of the QKDNf, overall operational procedures of QKDNf and security considerations.

Draft Recommendation ITU-T Y.QKDN-rsrq “Requirements for quantum key distribution network resilience” in TD404/WP3 For quantum key distribution networks (QKDN), Recommendation ITU-T Y.QKDN-rsrq specifies the general requirements for resilience, and separately specifies the supporting requirements for protection and recovery. Draft Recommendation ITU-T Y.QKDN-TSNfr “Framework for integration of quantum key distribution network and time sensitive network " in TD405/WP3 This Recommendation specifies the framework for integration of quantum key distribution network (QKDN) and time sensitive network (TSN) including the overview and scenarios of QKDN and TSN integration, the network capabilities to support QKDN and TSN integration, the conceptual structure and basic functions of QKDN and TSN integration, and its overall operational procedures and security considerations. Draft Supplement ITU-T Y.supp.QKDN_sync “Analysis of Synchronization in Quantum Key Distribution Networks” in TD406/WP3 This Supplement to ITU-T Y.3800-series Recommendations provides instructive information on time synchronization solution, function, and implementation in quantum key distribution networks (QKDN), including time synchronization function in quantum, key management, network management, and control layers of QKDN. 4. New work items agreed at the November 2023 SG13 meeting Draft Recommendation ITU-T Y.QKDN-nq-rf “Quantum key distribution networks – Requirements and framework for end-to-end QKDN and non-quantum cryptographies services” in TD411-R1/WP3 In order to support QKD service to IMT-2020 users including 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. TR-QKDN-nq addresses these issues and describes several use cases to deliver KSA-keys generated from QKD networks to the IMT-2020 user applications by means of modern cryptography (e.g., PKI technology) with PQC algorithms. It also identifies various issues to be addressed for standardization. One of them is an implication on the end-to-end QoS assurance. This draft Recommendation specifies use cases, architectural models, high-level and functional requirements for end-to-end QKDN and non-quantum cryptographies (NQC) services. Draft Recommendation ITU-T Y.QKD-TLS “Quantum Key Distribution integration with Transport Layer Security 1.3” in TD412/WP3 This Draft Recommendation specifies use cases, high-level requirements and reference models for quantum key distribution (QKD) integration with transport layer security 1.3 (TLS 1.3). Draft Recommendation ITU-T Y.QKDN-nq-qos-rf, “Quantum key distribution networks – Requirements and framework of quality of service assurance for end-to-end QKDN and non-quantum cryptography services” in TD549/WP1 This draft Recommendation specifies use cases, architectural models, high-level, functional requirements, and a framework for quality of service assurance of end-to-end quantum key distribution network (QKDN) and non-quantum cryptography (NQC) services. Draft Recommendation ITU-T Y.QKDNi-qos-fa “Quantum key distribution networks interworking - Functional architecture for quality of service assurance” in TD584/WP1 This draft Recommendation specifies the functional architecture of quality of service (QoS) assurance for the quantum key distribution network interworking (QKDNi), Draft Recommendation ITU-T Y.QKDN-da “Quantum Key Distribution Networks – Dependability Assessment in TD550/WP1 This Recommendation specifies QKDN dependability assessment conceptual model, indicators, and dependability assessment process. Draft Supplement ITU-T Y.supp.TC-QN “Technical considerations towards Quantum Network” in TD413-R1/WP3 Quantum network is expected to provide new applications based on fundamental quantum mechanics such as entanglement, superposition and non-cloning, and those are not possible with non-quantum networks (e.g. conventional digital networks). This Supplement aims to identify technical considerations for quantum network. 5. Conclusion SG13 will study the network aspects of QKD. Q16/13 and Q6/13 look forward to close cooperation with ITU-T SG2, SG11, SG15, SG17, ETSI ISG-QKD, ISO/IEC JTC1/SC27, WG14, AG4, IETF/IRTF, and relevant groups for future standardization on QKD networks.
