  2. Quantum key distribution: From concepts to applications QKD satellite ◼ First QKD experiment in IBM 1992 QKD commercial products QKD Network (QKDN) ◼ Quantum key distribution (QKD) ◼ Information theoretic security based on quantum physics IDQ, QCTEK, Toshiba, QRate, XT etc. EU SECOQC Tokyo Network Beijing-Shanghai Backbone 2

  3. International Standards Development Organizations (SDOs) ◼ International Organization for Standardization (ISO) ➢ Non-Governmental Organization, founded in 1947 ➢ An international standard-setting body composed of representatives from various national standards organizations ➢ Promotes worldwide proprietary, industrial, and commercial standards ◼ International Electro-technical Commission (IEC) ➢ Not-for-profit, quasi-governmental organization, founded in 1906 ➢ International standards for all electrical, electronic and related technologies, known as "electrotechnology“. ◼ International Telecommunication Union (ITU) ➢ Originally the International Telegraph Union created in 1865 ➢ A specialized agency of the United Nations for information and communication technologies ➢ The oldest global international organization ➢ The first international standards organization 3

  4. Standardization activities in SDOs ◼ European Telecommunications Standards Institute ( ETSI ) ➢ Standardization activities of QKD since 2008 ➢ All aspects of QKD: 8 specifications, 2 white papers ◼ ISO/IEC JTC1 ⚫ Information technology ➢ SC 27 WG 3: QKD implementation security ➢ SC 27 WG 2: Post quantum cryptography (PQC) ➢ WG 14: Quantum computing ◼ International Telecommunication Union ( ITU ) ➢ SG 13: QKDN network aspects ➢ SG 17: QKDN security aspects ➢ FG QIT4N WG2: QKDN terminology, use cases, protocols, transport etc (Pre-standardization) 4
