[Asia Economy Reporter Cha Min-young] LG Uplus held a briefing session at its Yongsan headquarters in Seoul with cryptography technology specialist Cryptolab on the 12th, introducing post-quantum cryptography (PQC) technology and its application cases.
Post-quantum cryptography is an encryption method that uses 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 can be implemented solely through software.
Cryptolab's lattice problem-based cryptographic algorithm was designated as a domestic standard by the Telecommunications Technology Association (TTA) in 2019.
At this briefing, Jeonghee Cheon, CEO of Cryptolab, explained why post-quantum cryptography is necessary in the era of quantum computers and why only PQC algorithms can create securely authenticated communication channels.
Guseong Cheol, head of LG Uplus's wired business overseeing related projects, introduced cases where LG Uplus implemented post-quantum cryptography on dedicated lines in public and private sectors as part of the Digital New Deal project.
Janghyuk Lim, General Manager (Executive Director) of LG Uplus's Enterprise Infrastructure Business Group, stated, “We will prepare for the ‘Post-Quantum Transition’ to strengthen the security of communication infrastructure overall through post-quantum cryptography that can withstand attacks from quantum computers.”
Meanwhile, LG Uplus made the first equity investment in the telecommunications industry in Cryptolab to secure post-quantum cryptography technology. Cryptolab is a cryptography technology company founded by Professor Jeonghee Cheon of the Department of Mathematical Sciences, who is also the director of the Industrial Mathematics Center at Seoul National University. The company holds patents related to post-quantum cryptography and homomorphic encryption, which allows computation on encrypted data without decrypting it.
