KIST Transfers Quantum Crypto Communication Device Technology to SDT
The Korea Institute of Science and Technology (KIST; President: Seok-Jin Yoon) and SDT Co., Ltd. (CEO: Ji-Won Yoon) held a signing ceremony for the technology transfer and commercialization of quantum cryptographic communication device technology at KIST's headquarters in Seoul on May 31.
Quantum computing technology is emerging as a serious threat to modern, mathematics-based security communication due to the rapid increase in computational speed. As a corresponding technology, research on quantum cryptography based on quantum mechanical laws is being actively carried out, and efforts are being made to commercialize related standards and systems as well as operate actual environmental test beds for products worldwide.
KIST has developed a network system for quantum cryptography communication and succeeded in achieving 1x4 communication using a quantum cryptography system from an actual installed optical cable network, and in 2021, it participated with a consortium of carriers to develop a quantum cryptographic communication system capable of connecting with existing cryptographic communication systems and verify its performance.
The technology transfer of the quantum cryptographic communication device, led by Han Sang Wook at KIST’s Center for Quantum Information, is the first quantum cryptographic communication system in Korea to enable 1xN (one-to-many) communication with multiple transmitter systems connected to a single receiver server. This system has the advantage of significantly lowering overall construction costs, as the single photon detector, quantum light source module, and so on, which represent a large portion of the development costs, are integrated into a single server, and it uses only relatively low-cost deployable parts found on a number of user transmitter systems.
Center for Quantum Information Head Han Sang Wook commented, "Utilizing the developed technology, it is expected to be effectively applied in various ways, such as in central control systems where secure communication is important, military communications which are connected to several subordinate units, and data server security communication that provides services to many users."
SDT provides cloud services based on data from edge device ecosystems and IoT sensors through the development of SoM (System-on-Module, Hardware, Communication, Software, Security, and Cloud Integrated Module) for various applications. Under this contract, communication between devices and the cloud will be protected with security that can never be hacked, and it is expected to further strengthen the competitiveness of SDT's products and services.
The President of KIST, Seok-Jin Yoon, stated, ‟This signing ceremony signifies our commitment to successfully commercializing the world's best quantum cryptographic communication device in Korea and cooperating more closely with companies to establish Korea as a quantum cryptographic communications powerhouse.ˮ
Ji-Won Yoon, the CEO of SDT, said, "Through the transfer of KIST’s quantum cryptography technology, we will strive to become a leader in the domestic digital transformation solutions market, and furthermore, we will lead Korea’s entry into the global market."
