LG Uplus Completes Performance Verification of Quantum-Resistant Encryption Network

[Asia Economy Reporter Joeslgina] LG Uplus announced on the 18th that the dedicated quantum-resistant encryption line built for industrial and medical sector companies as part of the Digital New Deal project has been tested and verified by the Telecommunications Technology Association (TTA).

Quantum-resistant encryption, a type of quantum security technology, can be applied to key security elements, offering high scalability and enabling long-distance transmission over hundreds of kilometers. Additionally, it can be implemented solely through software without requiring separate equipment. Because of this, it can be flexibly applied from mobile phones to small Internet of Things (IoT) devices, providing security across all areas of wired and wireless communication networks.

The company explained that TTA’s verification confirmed that the dedicated quantum-resistant encryption line, built in factories and hospitals using the world’s first commercial optical transmission equipment (ROADM) developed by LG Uplus and Cowiver last year, operates normally.

The test was conducted in March this year on the route between the National Information Society Agency (NIA) Seoul office and Pukyong National University in Busan, verifying 37 items in the industrial sector and 35 items in the medical sector related to the quantum-resistant encryption algorithm, encryption transmission equipment, and application service performance.

As a result of the inspection, the lattice-based quantum-resistant encryption algorithm, which uses a public key (asymmetric key) method employed by LG Uplus, far exceeded the test standards in terms of the time required for key generation and the memory capacity used in the key exchange process. Furthermore, the optical transmission equipment (ROADM) operating the algorithm supported the key exchange algorithm of quantum-resistant encryption, and the linkage with the quantum random number generator (QRNG) also operated without issues. In application services such as medical information systems, data upload and download succeeded 100%, and the processing times for Transport Layer Security (TLS) requests, server user login, authentication tokens, and PC application program linkage response all operated within one second.

Kwon Junhyuk, head of LG Uplus’s Network Division, said, "LG Uplus’s quantum security solution for the industrial and medical sectors, which passed TTA’s test and verification, will provide higher security across a wider range of industries this year. LG Uplus will take the lead in upgrading the algorithm further to expand a more universal and highly usable quantum security infrastructure."
