LG Uplus announced on the 20th that it will apply a Post-Quantum Cryptography (PQC) based security system to key systems of the Korea Communications Agency (KCA). This project is part of the '2025 PQC Pilot Transition Support Project' led by the Korea Internet & Security Agency (KISA), with participation from the Korea Information & Communication Technology Association (TTA) and KCA.
PQC is a next-generation encryption technology that is difficult to decrypt even with quantum computers, supplementing vulnerabilities in existing encryption systems. LG Uplus plans to apply PQC modules to security infrastructures such as VPN, Virtual Desktop Infrastructure (VDI), and Computer-Based Testing (CBT), with verification expected to be completed within this year.
Patented technology that optimizes and selectively uses seven algorithms designated by the U.S. National Institute of Standards and Technology (NIST) and the domestic KpqC has also been applied. LG Uplus commercialized PQC-based dedicated lines and optical transmission equipment for the first time in the country since 2020, and this year it launched the integrated account management solution "AlphaKey."
In particular, the "Optical Transmission Network PQC Application Standard Draft" has been selected as a "2024 Excellent TTA Standard" and has become the standard for PQC application in domestic optical communication networks. It diagnoses vulnerabilities in existing encryption systems and supports transition through a testbed led by the National Information Society Agency (NIA).
LG Uplus believes that PQC will be widely applied across various industries such as autonomous driving, smart cities, and financial and public infrastructure, and plans to accelerate technology development.
