KT Transfers Core Quantum Encryption Communication Technology to SMEs

[Asia Economy Reporter Koo Chae-eun] KT announced on the 28th that it has signed a contract to transfer quantum cryptography communication technology, developed in-house over the past three years, to domestic small and medium-sized enterprises (SMEs) such as Woorinet Co., Ltd.

The quantum cryptography communication technology that KT is transferring to SMEs is the "Quantum Key Distribution (QKD) system." The QKD system is one of the core quantum cryptography communication technologies that supplies quantum-generated "keys (encryption keys)" to communication networks to encrypt data in a state that is difficult to hack or eavesdrop on.

KT began research and development in 2018 and produced the first prototype of the quantum key distribution system in 2019. Since then, following the "Open Layered Architecture (Y.3800)" standard, KT has linked domestic SMEs' encryption equipment with the quantum key distribution system and applied it to 5G networks in some areas of Gyeonggi Province last April. This resulted in enhanced security without any reduction in customer data speed or delays, enabling smooth communication.

Going forward, the SMEs that signed the technology transfer contract plan to manufacture quantum cryptography key distribution equipment using only domestic technology based on KT's quantum key distribution system technology, conduct technical tests with KT, and participate in various quantum cryptography communication network construction projects. KT expects that this technology transfer contract will create synergy by combining KT's quantum cryptography communication technology with the equipment manufacturing know-how of SMEs, thereby advancing the level of Korean quantum cryptography communication technology to the next stage.

Lee Jong-sik, Director of KT Infrastructure Research Center, said, "This technology transfer has great significance in solidifying the quantum cryptography communication ecosystem through mutual growth and securing leadership for KT and domestic SMEs to lead the global market in this field." He added, "KT will continue to research and develop quantum cryptography communication technology and exchange this technology with domestic SMEs to contribute to the enhancement of Korea's industrial capabilities."
