KT Achieves World's First ITU International Standard Approval for Quantum Cryptography Communication Quality Evaluation Criteria

[Asia Economy Reporter Lim Hye-sun] KT announced on the 23rd that its independently developed quantum cryptography communication service quality evaluation standard has been approved as the world's first international standard by the International Telecommunication Union (ITU).

Quantum cryptography communication is a next-generation security technology based on quantum technology, and various fields such as finance, medical care, defense, and research institutions are considering its adoption to enhance security.

The "Quantum Cryptography Communication Service Quality Evaluation Standard," independently developed by KT and approved as the world's first ITU international standard, can measure service quality by applying specialized parameters according to Response Delay, Response Delay Variation, and Loss Ratio. Therefore, it is characterized by the ability to provide customers with objective quality information. Through this, it is possible to stipulate the Service Level Agreement (SLA), which is a required notification item for the commercialization of dedicated quantum cryptography lines.

In particular, KT applied this standard to the quantum cryptography communication network management system it has built and operates independently. This has created an environment capable of providing high-quality services through quality improvement by quickly and accurately objectively evaluating the actual quality of quantum cryptography communication.

Until now, quantum cryptography communication technology was comparatively evaluated based on the performance of quantum key distribution devices. However, for actual service provision, multiple devices are connected in a network form over long distances, resulting in differences from the service quality perceived by customers.

KT plans to continuously develop various technical standards and service packages, including the quantum cryptography communication service quality evaluation standard, to lead the related industry. KT's quantum cryptography communication technology is currently being applied throughout society. Gangwon Provincial Office and the 2nd Army Corps enhanced security by integrating KT's quantum cryptography communication technology into the video transmission and reception system of drones used for missing person searches.

Additionally, Jeju Provincial Office applied KT's quantum cryptography communication solution in certain sections to protect communication between autonomous vehicles and control centers, preventing accidents caused by hacking or external intrusion.

Recently, KT implemented a high-speed quantum key distribution system providing quantum cryptographic keys at 20kbps and directly developed core components such as the "High-speed Single Photon Source Generation Module" and the "High-speed Quantum Random Number Linked Interface."

KT has been globally recognized for its technological prowess in the quantum cryptography communication field by succeeding in the world's first international standardization of quantum cryptography network operation management service quality evaluation, following the development of quantum channel automatic switching recovery technology for service stabilization and single optical cable transmission of quantum and data channels.

KT is also leading the establishment of a domestic quantum cryptography communication ecosystem. Through five supply contracts for quantum key distribution devices, KT has transferred quantum technology to domestic small and medium-sized enterprises and plans to provide technology to more than five SMEs this year as well.
