It is noteworthy that the quantum cryptographic communication technology, which cannot be hacked in the first place in Korea, is about to be commercialized as concerns about hacking have increased.
SK Telecom succeeded in demonstrating long-distance communication by overcoming distance limit of existing quantum cryptographic communication. The company is expected to commercialize it from end of this year to early next year. It is expected that the quantum cryptographic communication market will grow rapidly in connection with the majority of industries which need security such as administration and defense.
SK Telecom announced, on June 19, that it succeeded in developing a relay device dedicated to quantum cryptography in Korea and succeeding in transferring the quantum cryptographic key from the test network of 112 km round trip from Bundang to Yongin and Suwon.
Quantum cryptographic communication is a communication cryptographic technique which applies the non-replicable characteristics of both energy units. In the transmission section, it is known as a communication security system that cannot be penetrated by any existing hacking technology. The use of quantum cryptographic communication services is extremely high in other industries where information security is essential, such as administrative, defense, financial, and medical services, as well as the term communication network.
In the case of connecting multiple relay devices dedicated to quantum cryptography developed by the company, quantum cryptography can be used for hundreds to thousands of kilometers. Since quantum cryptography uses a weak signal at a single quantum level, the existing distance limit is about 80 km. The company has developed a relay device dedicated to quantum cryptography and has been able to transmit quantum cryptographic keys over 80 km. For instance, it is possible to receive the quantum cryptographic key sent from Seoul in Busan, if only five dedicated relay devices are installed in between Seoul and Busan (about 460km).
The company plans to apply a dedicated relay to the commercial network by the end of this year and gradually expand the quantum cryptographic communication service. The company also plans to develop a dedicated relay device which can send a large number of quantum cryptographic keys to various destinations at the same time and apply it to commercial networks. It was applied to the LTE network wired section of the commercial Sejong City last year in the case of the existing 80km quantum cryptographic communication. In May of last year, Korea Institute Science and Technology Information (KISTI) has been providing quantum cryptographic communication services in some sections of the Daedeok Science and Technology Research Network in cooperation with Korea Institute of Science and Technology Information (KISTI).
The company is currently negotiating the provision of bilateral cryptographic communication services with multiple Korean public institutions, and expects to be able to commercialize it through a contract between the end of this year and early next year.
The industry expects that the industrialization of quantum cryptographic communication technology will become even more rapid if the legislation passed by the Lee Eun-kwon (Liberty Korea Party) in January this year enacted the ‘Act on the Development of Quantum Information and Communication Technology and Promotion of Industrialization’. The bill contains information on establishing a systematic upbringing system for bilateral information and communication technology and establishing a comprehensive development plan to promote industrialization.
Market Research Media, a market research company, predicted that the Korean quantum information and communications market will grow to about KRW 1.4 trillion by 2025, which will grow rapidly from 2021. The world market is expected to reach KRW 26.9 trillion in 2025.
Currently, countries around the world believe that quantum information communication is the key technology which will lead to new market creation and change the security paradigm in the forthcoming industrial revolution era. Especially, China and the United States are ahead in technology development.
Meanwhile, SK Telecom explained that it developed 100% of the relay device for quantum cryptography communication with Korean technology. The company has established a quantum technology research institute since 2011 to develop the technology of quantum cryptography. The company also stated that the dedicated relay device was created after the last two years of effort, thanks to the support of the National Science and Technology Department`s `construction of a quantum cryptography test bed` for national projects. The company plans to cooperate with overseas companies to apply quantum cryptographic communication solutions including dedicated relay devices to overseas commercial networks.
