KT Launches Dedicated Quantum Cryptography Communication Line "Suitable for Public, Defense, and Financial Sectors"

Minimum 40 Million KRW per Month for Contracts Over 7 Years

[Asia Economy Reporter Cha Min-young] KT announced on the 10th that it launched a dedicated quantum cryptography communication network line service on the 1st of this month and is officially entering B2B sales targeting the public sector, organizations, and companies.

Quantum cryptography communication is a next-generation security communication technology that transmits information by exchanging encryption keys in a way that cannot be intercepted in the middle, utilizing the principles of quantum mechanics.

KT's dedicated quantum cryptography communication line service implements encryption using the 'Quantum Key Distribution device' (QKD, a device that generates quantum encryption keys). KT explained that this dedicated equipment is based on technology independently developed by KT and approved as an international standard, ensuring high compatibility and scalability. In particular, it can be applied to necessary sections without switching or rebuilding the dedicated line, as it can use the existing KT dedicated line as is.

The usage fee for the dedicated quantum cryptography communication line includes the existing dedicated line usage fee, quantum channel usage fee, and rental fees for quantum communication encryption equipment (QENC), quantum key management system (QKMS), and QKD devices.

The fee structure is composed of a monthly rate of 100 million to 340 million KRW based on a 3-year contract, depending on distance regardless of speed. For long-term contracts over 7 years, the usage fee is at least 40 million KRW per month, allowing the service to be used at more than 50% lower cost than a 3-year contract. The equipment rental fee is 16.5 million KRW per month for devices supporting up to 1Gbps speed and 17.6 million KRW for 10Gbps devices. For example, the monthly fee for 1Gbps quantum cryptography communication service on the Seoul?Yongsan section is 116.5 million KRW (based on a 3-year contract).

KT is developing a high-speed quantum cryptography communication system and conducting research and development for the demonstration of the longest domestic quantum cryptography communication service between Seoul and Busan, as well as leading international standardization.

Baek Seung-taek, head of KT's Data Infrastructure DX (Digital Transformation) business, said, "Based on the largest number of international standards related to quantum cryptography communication in the world, KT can provide strong security services in fields such as public, defense, and finance," adding, "Through continuous service development, we will lead the quantum cryptography communication field not only in Korea but also globally."
