South Korea launches the world's first post-quantum cryptographic line

South Korean mobile operator LG Uplus (LG U+) has launched South Korea's first post (anti)quantum cryptography (PQC) commercial service, which can defend against hacking attacks on quantum computers. This is also the world's first post-quantum cryptographic dedicated line service.

Post-quantum cryptography (PQC) is a cryptographic technique that is secure against all attacks by quantum computers, which are theoretically 10 million times faster than existing supercomputers. Because it is based on complex mathematical algorithms, it would take trillions of years to decipher even with a quantum computer.

"U+ Post-Quantum Cryptographic Line" provides a secure environment that cannot be hacked by applying the technology's "Reconfigurable Optical Add-Drop Multiplexer" (ROADM): when customers transmit/receive data through the private line, they can use post-quantum The method by which a cryptographic key encrypts/decrypts data.

Using ROADM, an optical transmission device, to test a dedicated backbone network can meet the needs of various enterprise customers and respond first to increased traffic. The backbone provides enhanced availability through low latency, multi-route diversity, and direct connectivity between major cities.

LGU+ said that the normal operation of the line dedicated to quantum-resistant cryptography has been tested and verified by the Telecommunications Technology Association (TTA): As early as May 2021, the quantum-resistant cryptographic lines established by LGU+ in factories and hospitals have been standardized and tested by the state and certification body Telecommunications Technology Association (TTA). The algorithm used by LGU+ was found to exceed the TTA's testing standards and had no problems linking it with application services and programs.

LG U+ said: "In the era of the fourth industrial revolution, all IT-related hardware and software use different passwords, and many companies store and process large amounts of big data, so it is very important to establish a system that prevents the risk of hacking attacks in advance. "

Since all IT-related hardware and software use different passwords, and many companies store and process large amounts of big data, systems that protect against the risk of hacking are very important. Interest in post-quantum cryptography is increasing worldwide due to its excellent security. The U.S. Department of Homeland Security (DHS) and federal agencies have developed a quantum roadmap by 2030; global companies such as IBM, Google, and Amazon are standardizing post-quantum cryptography under the leadership of the National Institute of Standards and Technology (NIST) Work.

LG U+ is planning to apply this technology to wired and wireless communications beyond private lines through technological advancements. "LG U+ will create the necessary technological environment and industrial ecosystem through the commercialization of post-quantum cryptographic services to promote the quantum information and communication industry to become a national core industry based on U+ technology," said Kuh Sung- , head of LG U+'s cable business. Cheol said. "We will innovate the coming era of quantum computing with secure high security."
