[Asia Economy Reporter Seolgina Cho] LG Uplus announced on the 1st that it has made an equity investment in CryptoLab, a next-generation cryptography technology company, and will strengthen the security of its communication network.

CryptoLab is a cryptography technology company founded by Professor Jeonghee Cheon of the Department of Mathematical Sciences, who is also the head of the Industrial Mathematics Center at Seoul National University. The company holds patents for quantum-resistant cryptography (PQC), which enhances security using complex algorithms that would take billions of years for quantum computers to solve, and homomorphic encryption, which allows computation on encrypted data without decrypting the original data.

Through this investment, LG Uplus plans to enhance security by applying quantum-resistant cryptography across all segments of its commercial communication network. Additionally, based on the scalability of quantum-resistant cryptography, it will develop technologies to establish quantum security systems not only for wired networks but also for mobile communication networks such as 5G and 6G.

Furthermore, LG Uplus and CryptoLab have agreed to accelerate the commercialization of technology and cooperate to obtain security certification from national security agencies to revitalize the domestic and international quantum-resistant cryptography ecosystem. Quantum-resistant cryptography is implemented in software, allowing it to be applied to all communication networks, and has a wider range of applications compared to other quantum cryptography methods. However, high implementation costs are considered a limitation.

The two companies also plan to explore ways to commercialize 4th generation homomorphic encryption technology, which is regarded as an essential tool when utilizing big data.

Choi Taekjin, Vice President and Head of LG Uplus Enterprise Division, said, “CryptoLab’s excellent cryptographic technology will make a decisive contribution to strengthening the security of communication networks and all LG Uplus services. We will do our best to create a security system that customers can trust during the development and commercialization of equipment applying quantum-resistant cryptography technology.”

Jeonghee Cheon, CEO of CryptoLab, said, “Lattice-based quantum-resistant cryptography, which boasts solid security based on mathematical problems, is expected to accelerate a safer future with enhanced information protection when applied not only to communication networks but also to various industrial fields. Through cooperation with LG Uplus, we will accelerate technology development and establish a foundation to enhance national security competitiveness.”
