KT, First Public Release of Quality Evaluation Standards for Quantum Cryptography Communication Networks

[Asia Economy Reporter Minyoung Cha] KT has unveiled for the first time the "Quality Evaluation Criteria for Quantum Cryptography Communication Networks," which is being standardized by the International Telecommunication Union (ITU) with leading research institutions from Korea, China, and Japan.

KT announced on the 24th that it held a two-day online quantum cryptography communication standardization workshop starting on the 23rd with representative research institutions from Korea, China, and Japan.

The workshop included participants from ETRI (Electronics and Telecommunications Research Institute, Korea), CAS (Chinese Academy of Sciences), NICT (National Institute of Information and Communications Technology, Japan), and the ITU Korea-China-Japan chairpersons, who presented the current status of quantum cryptography communication technology development in each country.

The quality evaluation criteria disclosed by KT this time include essential standards for assessing the quality of quantum cryptography communication network services, such as "Response Delay," "Jitter," and "Key Loss Rate." Once this standard is finalized by the ITU by the end of this year, it is expected to become the SLA standard for dedicated quantum cryptography communication network line services and quantum key supply services. KT also presented cases where its self-developed quantum cryptography communication technology was applied to domestic small and medium-sized enterprises.

Additionally, the current status of international quantum cryptography communication standards being developed by ITU, JTC1 SC27 (Joint Technical Committee 1 Subcommittee 27 of the International Electrotechnical Commission), and ETSI (European Telecommunications Standards Institute) was shared, and future mutual cooperation plans for standardization were discussed.

Meanwhile, KT has led a total of 10 ITU international standards since the world's first quantum cryptography communication international standard in 2018. It has also completed 6 out of 10 domestic quantum cryptography communication standards.

Jongsik Lee, Head of the Infra Research Institute at KT Convergence Technology Institute, said, "KT has made great efforts to revitalize the domestic quantum cryptography communication ecosystem and to advance domestic technology into the global market. Based on this workshop, we will strengthen ties with experts worldwide and further strive for the development of domestic and international standards and to maintain a competitive edge in quantum technology."
