[Asia Economy Reporter Kim Heung-soon] LG Uplus is applying 'Post-Quantum Cryptography (PQC)' technology to the industrial and medical sectors where security is crucial. Post-Quantum Cryptography is a next-generation encryption technology that can respond to security threats posed by high-performance quantum computers in the future, utilizing encryption algorithms that cannot be solved even by the computational power of quantum computers.

LG Uplus announced on the 1st that it has completed the establishment of dedicated lines based on post-quantum cryptography for LG Innotek and Eulji University Hospital and will conduct verification by the end of this month. LG Uplus explained, "Once quantum computers become commercialized, they will be able to decrypt codes that currently take a supercomputer with the highest specifications a million years to solve within seconds," adding, "Post-Quantum Cryptography encrypts information with new algorithms that would take tens of thousands of years even for such quantum computers, preventing hacking threats."

Specifically, post-quantum cryptography technology is applied to the dedicated line sections of 640 km connecting LG Innotek’s Pyeongtaek factory and Busan IDC, and 207 km connecting Eulji University Hospital’s Nowon and Daejeon branches. Through this, the security of dedicated line sections spanning hundreds of kilometers between the company’s factories and branches or hospital main and branch offices can be enhanced by applying encryption modules without any separate configuration changes.

LG Uplus emphasized, "This technology can be applied to protect information safely from hacking when companies exchange data not only domestically but also with overseas branches," and added, "In the future, it will be possible to secure communication channels between hospitals and individuals handling sensitive information, such as 'non-face-to-face remote medical care,' which is part of smart healthcare."

The establishment of dedicated lines based on post-quantum cryptography is part of the Ministry of Science and ICT’s 'Digital New Deal Plan' and corresponds to the 'Quantum Cryptography Communication Pilot Infrastructure Construction and Operation Project' announced by the National Information Society Agency (NIA).

Goo Sung-cheol, head of LG Uplus’s wired business division, said, "Post-Quantum Cryptography is an innovative technology that can provide security services not only for wired network sections but also for wireless networks, smartphones, and Internet of Things (IoT) devices through software methods," adding, "We will strive to develop specialized application services for each industry and expand application cases in the future."
