LG Uplus made an announcement on Dec. 27 that it has succeeded in developing a quantum security chip for IoT terminals for the first time in Korea with security system-on-chip (SoC) developer ICTK Holdings, an information security startup EYL, and LG CNS.
This is expected to further strengthen the security of IoT devices ranging from autonomous vehicles and drones to corporate and home CCTVs.
Quantum security is a technology that prevents duplication and prediction of encryption keys by generating unpredictable and patternless pure random numbers with "QRNG (Quantum Random Number Generator)."
Compared to TRNG (True Random Number Generator), which is a security technology used in existing IoT devices, it is safer from hacking threats due to the high randomness of passwords.
The three companies combined these QRNGs into a "PUF (Physical Unclonable Function)" and composed them as a "quantum security chip (CPUF).
QRNG and PUF send and receive data directly from each other within a chip. This will help customers prevent privacy violations and information leakage.
Each company expects that this quantum security chip can be applied to IoT devices that are actually being used as early as the first half of next year. Through this, the company plans to maximize the security of IoT devices that have become important recently.
"As a leader in the IoT market, we focused on developing this technology to prevent infringement of customers' privacy and information leakage," said Jeon Young-seo in charge of LG Uplus' corporate service development.
Meanwhile, LG Uplus said earlier this month that it has established a dedicated communication line based on post-quantum cryptography at LG Innotek and Eulji University hospitals.
It applied post-quantum cryptography technology to 640km of the exclusive line connecting LG Innotek's Pyeongtaek plant and Busan IDC, and 207km of the exclusive line between Nowon of Eulji University Hospital and Daejeon.
