The Use Cases Document shall provide an overview of possible application scenarios in which Quantum Key Distribution (QKD) systems ([i.1]) can be used as building blocks for high security Information and communication technology (ICT) systems.
The present document is intended to specify an Application Programming Interface (API) between a QKD key manager and applications. The function of a QKD key manager is to manage the secure keys produced by an implementation of a QKD protocol and to deliver the identical set of keys, via this API, to the associated applications at the communication end points.
The present document gives specifications and procedures for the characterization of optical components for use in QKD systems. Examples of specific tests and procedures for performing such tests are given. Due to their importance in the security of a QKD system, particular attention is given to active optical components such as optical sources and single photon detectors.

The present document specifies a communication protocol and data format for a quantum key distribution (QKD) network to supply cryptographic keys to an application.
The present document provides a definition of management interfaces for the integration of QKD in disaggregated network control plane architectures, in particular with Software-Defined Networking (SDN). It defines abstraction models and workflows between a SDN-enabled QKD node and the SDN controller, including resource discovery, capabilities dissemination and system configuration operations. Application layer interfaces and quantum-channel interfaces are out of scope.
Recommendation ITU-T Y.3802 defines a functional architecture model of quantum key distribution (QKD) networks. In order to realize this model, it specifies detailed functional elements and reference points, architectural configurations and basic operational procedures of QKD networks (QKDN).
Recommendation ITU-T Y.3803 provides help for the design, deployment, and operation of key management of a quantum key distribution network (QKDN).
Recommendation ITU-T X.1712 specifies security threats and security requirements for key management in quantum key distribution networks (QKDNs), and then it specifies security measures of key management to meet the security requirements. This Recommendation provides support for design, implementation, and operation of key management in QKDN with approved security.
The objective of this Recommendation is to provide guidance on security requirements for trusted nodes in QKD networks. This Recommendation will identify the security threats and provide security requirements of trusted node, as well as some implementation examples to meet the requirements.
This standard defines the Software-Defined Quantum Communication (SDQC) protocol that enables configuration of quantum endpoints in a communication network in order to dynamically create, modify, or remove quantum protocols or applications. This protocol resides at the application layer and communicates over Transmission Control Protocol/Internet Protocol. The protocol design facilitates future integration with Software-Defined Networking and Open Networking Foundation OpenFlow. The standard defines a set of quantum device configuration commands that control the transmission, reception, and operation of quantum states. These device commands contain parameters that describe quantum state preparation, measurement, and readout.
