2. Objectives

• The JCA-QKDN ensures that the ITU-T QKDN standardization work is progressed in a well-coordinated manner among relevant study groups, in particular, Study Group 11 on protocols and interoperability, Study Group 13 on network architecture and functions, and Study Group 17 on security.
• ​Whenever duplication of effort or planning issues are discovered, the JCA-QKDN will coordinate all activities related to QKDN with relevant study groups and report the results to TSAG. ​
• The JCA-QKDN considers and encourages possibilities of co-operation on QKD related standardization with relevant SDOs such as ISO/IEC JTC1, ETSI, IEEE, IETF/IRTF, CCSA, CEN-CENELEC FG QT, IEC TC 86, etc.​
• The JCA-QKDN analyses the work of standards development organizations, consortia and forums for use in its coordination function and as part of its report provides information on this work for use by the relevant study groups in planning their work.​
• In order to avoid duplication of work and assist in coordinating the work of the study groups, the JCA-QKDN acts as a point of contact within ITU-T and with other standards development organizations, consortia and forums working on QKD related standards.
• The JCA-QKDN maintains the SG13 roadmap for QKDN standardization which addresses on-going and published specifications from ITU, other relevant standard development organization, consortia and forums.
• In carrying out the internal coordinating role, participants in the JCA-QKDN will include representatives of relevant ITU-T study groups and other ITU groups.​
• In carrying out the external collaboration role, representatives from other relevant standards development organizations, regional/national organizations, consortia and forums shall be invited to join the JCA-QKDN.
