(AJU.Daily) Quantum-resistant cryptography lines established by LG Uplus in factories and hospitals have been verified by a standardization, testing and certification body in South Korea. The mobile carrier said it would upgrade algorithms to realize the wider use of quantum security infrastructure in various fields in the era of digital transformation, a process of converting analog-based work processes into an automated digital one.
LGU+ said that the normal operation of lines dedicated to quantum-resistant cryptography has been tested and verified by the Telecommunications Technology Association (TTA). In a test in March, algorithms used by LGU+ were found to have exceeded TTA’s test criteria and showed no problem in linking it with application services and programs.
LGU+ has commercialized post-quantum cryptography (PQC) technology, which refers to cryptographic algorithms that are thought to be secure against an attack by a quantum computer. Cryptographers are designing new algorithms to prepare for a time when quantum computing becomes a threat. PQC does not require separate network infrastructure to distribute cryptographic keys because it can be applied flexibility to different sections of wired and wireless networks that require encryption.
