‘Quantum cryptography communication system’ selected by three telecommunication companies as a solution for communication security

It is a technology that boasts excellent security so that hacking is theoretically impossible, and has received attention for its safety that surpasses existing encryption techniques.
According to the industry on the 16th, SK Telecom and LG U+ recently began developing quantum communication technology with Seoul National University, and KT also completed verification of the performance of a hybrid quantum security network with Shinhan Bank.
SK Telecom establishes ‘Quantum Alliance’ with 7 companies possessing core technologies
Quantum cryptography systems became possible with the development of quantum computers. A quantum computer can decrypt a password in just 100 seconds, which used to take 1 billion years to decrypt using general computing technology, threatening the ‘public key cryptosystem’ (RSA), an existing information security system based on mathematical difficulties. I’m doing it.
The quantum encryption system, which has emerged as an alternative, completely prevents the duplication of encryption keys that were previously exchanged only between the sender and receiver. Unlike general encryption keys that encrypt and transmit predetermined information, quantum cryptography technology determines the information value the moment it is received, making it safe even if the encryption key information is stolen during the transmission and reception process. Since the information changes during external infiltration, it is possible to immediately identify whether there has been a hacking attempt.

SK Telecom has been conducting related research since establishing the Quantum Technology Research Center in 2011. At the last ‘Mobile World Congress (MWC) 2024’, a quantum AI camera with vision artificial intelligence (AI) technology and a case of application of quantum key distribution (QKD) for communication security of next-generation AI data center (DC) technology were introduced.
We plan to strengthen domestic and international competitiveness and advance into the global market by establishing the ‘Quantum Alliance’ with companies possessing core technologies and components in the quantum field. The Quantum Alliance included SOS Lab, Xgate, Wooriro, KCS, Nokia, and IDQ Korea.
KT expands encrypted communication transmission and reception by 10km… LGU+ publishes ‘white paper’ with Seoul National University
KT recently built a temporary hybrid quantum security network in the financial system and completed performance verification. KT’s hybrid quantum security network combines QKD and quantum-resistant cryptography (PQC). The security network used the draft quantum-resistant public key encryption algorithm selected from the ‘US Federal Information Processing Standard (FIPS)’, an information technology standard developed and officially announced by the US federal government. KT began developing wireless quantum cryptography communication technology in 2021 in cooperation with many organizations, including small and medium-sized enterprises, and is continuing research to expand the wireless quantum cryptography communication data transmission and reception section from the existing 2km to 10km this year. Previously, in 2022, wireless quantum signals were transmitted in a 1km section of Dongjak Bridge over the Han River, and a wireless quantum cryptography communication infrastructure was built on a pilot basis at Jeju National University in a 300m section, and last year, it succeeded in expanding the section limit to 2km at Cheongpyeong Lake in Gapyeong. Professor Kyung-Han Lee’s research team and LG U+ employees discuss the contents of the white paper at Seoul National University’s NXC lab. / Photo = Provided by LG U+ LG U+ published the ‘Future Quantum Communication White Paper’ with the Seoul National University research team on the 14th. The white paper largely categorizes quantum information technology into quantum communication, quantum computing, and quantum sensing, and specifically introduces the technology trends and development directions of quantum communication in detail.
LG U+ upgraded its quantum security system through a quantum cryptography communication infrastructure construction project in 2021 and expanded its application to application services in the performance and entertainment fields. In April 2022, it is the first telecommunications company to launch a quantum-resistant encryption dedicated line service that can respond to the hacking threat of quantum computers, and is providing the service to public institutions and private users. Demand for quantum cryptography communication is expected to steadily increase. According to the ‘Quantum Information Technology White Paper’ published by the Korea Intelligence and Information Society Agency (NIA) together with the Ministry of Science and ICT, the global market size for quantum cryptography communication will increase by an average of 39.8% annually following 2022, expanding to KRW 24.5793 trillion in 2030. It is expected that it will be. The government announced an investment plan worth a total of 3 trillion won by 2035 through the ‘Korea Quantum Science and Technology Strategy’.
An industry official explained, “Quantum computers will not be introduced and commercialized right away, but each company is preparing in advance and trying to gain the upper hand in quantum cryptography communications. Mobile carriers are responding quickly amid rapidly changing technological developments.” .
