Development of 'quantum hybrid technology' that implements quantum cryptography communication in smartphones

A technology that can easily and quickly apply quantum cryptography communication with one smartphone application (app) without having to use a terminal exclusively for quantum cryptography communication has been developed.

KT made an announcement on April 20 that it has developed 'quantum hybrid' technology that can implement quantum cryptography communication technology through smartphone apps.

Previously, quantum security communication could be used only when quantum security terminals or separate quantum communication terminals were installed with quantum random number generator (QRNG).

If KT applies this technology, you do not need to purchase additional dedicated terminals, which is highly efficient in terms of cost and management.

'Quantum Hybrid Technology' is a one-time installation of 'QS-VPN' app and can be applied to current smartphones. It combines Quantum Key Distribution (QKD) technology with Post Quantum Cryptography (PQC) to block hacking threats in 5G virtual networks (VPN).

KT has strengthened its safety by applying PQC, which is likely to be selected as a standard for quantum cryptography-resistant algorithms from the U.S. National Institute of Standards and Technology (NIST).

PQC is an algorithm that provides secure resistance to all attacks using quantum  computers in a network segment.

KT is planning to expand this technology to 5G application services that are very important for security such as finance and connected cars.

"With the development of 'Quantum Hybrid' technology, we will continue to research and commercialize quantum security platforms that customers can use with confidence in the era of digital transformation (DX)," said Managing Director Lee Jong-sik of KT Infrastructure Research Institute.
