[Asia Economy Reporter Koo Eun-mo] LG Uplus announced on the 1st that it has developed a security application based on quantum-resistant cryptography (PQC) technology in collaboration with security specialist ICTK Holdings, and significantly enhanced security by applying it to the Eulji University Hospital medical information system.

The medical information system consists of electronic medical records (EMR), picture archiving and communication system (PACS), and order communication system (OCS), storing patients' sensitive medical information, thus requiring enhanced security. LG Uplus adopted quantum-resistant cryptography technology as the next-generation security technology in the medical field. Quantum-resistant cryptography is an encryption method using complex mathematical algorithms that would take billions of years to solve with a quantum computer. It can be applied to core security elements such as key exchange, data encryption/decryption, and integrity authentication, and has the advantage of being implementable with software alone without additional hardware.

Previously, LG Uplus and ICTK Holdings developed a security token (Q-PUF USB) that combines hardware security technology with quantum-resistant cryptographic password authentication to implement multi-factor authentication. This time, they developed a separate app utilizing quantum-resistant cryptography to strengthen security during data transmission and access in the Eulji University Hospital medical information system.

Medical personnel using the medical information system at the hospital connect a USB-type security token to their PC and enter their ID and password to access the data center. The process involves performing public key authentication with the server using a certificate stored in the security chip, after which access is granted.

LG Uplus stated, "The significance of this app development lies in demonstrating that quantum-resistant cryptography can be used for information protection even in the medical field where large amounts of data are transmitted," adding, "LG Uplus is expanding the use of quantum-resistant cryptography across optical communication equipment (ROADM), USB-type security tokens (Q-PUF USB), and apps, creating a comprehensive security system effective even in the quantum computing era."

Seol Chul Koo, Head of Wired Business at LG Uplus, said, "Through the Digital New Deal project, collaborating with Eulji University Hospital to enhance the security of actual medical data using quantum-resistant cryptography gives great significance to this app development," and added, "We will build strong security effective in the quantum computing era across all segments where data is delivered to customers, including communication networks."

Jungwon Lee, CEO of ICTK Holdings, said, "Our world's first mass-produced PUF technology combined with quantum-resistant algorithms and actual data from Eulji University Hospital, along with LG Uplus's leadership in communication and security, created synergy that led to excellent results. We hope this security technology will be widely applied and contribute to strengthening Korea's security level."

This quantum-resistant cryptography medical information system was developed through the Digital New Deal quantum cryptography communication pilot infrastructure construction and operation project by the Ministry of Science and ICT and the National Information Society Agency (NIA).
