KT Releases New Technology for Easy Application of Quantum Cryptography Communication with Smartphone App

(AjuDaily) KT, a major telecom company in South Korea, released a new technology that enables the quick and easy application of quantum cryptography communication with smartphone applications. The “quantum hybrid” technology is efficient in terms of cost and management as users do not need to purchase dedicated terminals.
KT said it would expand its technology to 5G application services, where security is very important, such as finance and connected cars.
Quantum hybrid technology can be applied with a single installation of the QS-VPN app to smartphones, KT said, adding it combines quantum key distribution (QKD) technology with post-quantum cryptography (PQC) technologhy to fundamentally block hacking threats from a 5G virtual private networks (VPN).
In the 5G era, the importance of cybersecurity in mobile communications will rise exponentially. Quantum cryptography has emerged as an essential solution for safeguarding critical information because it is impossible to copy data encoded in a quantum state.
KT has been selected by the Korea Information Society Agency (NIA) to set up and test a quantum cryptography network. KT and LGU+, a mobile carrier, have jointly developed a new quantum cryptographic technology to win approval from the International Telecommunication Union (ITU), an international telecommunication technology standardization governing body
