KT Corporation developed the new ‘quantum hybrid’ technology, which enables smartphones to apply quantum cryptography communication, enhancing cybersecurity solutions.

KT Corporation revealed that it had developed the new ‘quantum hybrid’ technology that provides quantum cryptography communication for smartphone usage. Recently, security threats generated from quantum computers have increased, prompting cryptographers to design more robust algorithms and develop better security systems. To this end, KT introduced the quantum hybrid technology, which enables quick and easy quantum cryptography communication applications to smartphones.

Quantum Hybrid

According to KT, users could apply the new technology to their smartphones by installing the ‘QS-VPN’ app. Moreover, KT noted that it integrated quantum key distribution (QKD) methods with post-quantum cryptography (PQC) algorithms. In particular, QKD supplies two communicating parties with a random secret key, enabling them to encrypt and encrypt data. QKD methods also notify the users when a third party attempts to access the key covertly. Furthermore, cryptographers consider PQC algorithms to be safe against quantum computer attacks.

Thanks to the QKD and PQC combination, KT developed the quantum hybrid, which fundamentally prevents security breaches from 5G virtual private networks (VPN). KT also fused PQC methods with the blockchain-based decentralized identity (DID) system, protecting user identification. Additionally, KT stated that DID technology uses smartphone terminals to store user information and other authentication, significantly preventing data leaks.

Improving Quantum Security

“With the development of the quantum hybrid technology, we will continue to research and commercialize a quantum security platform that customers can use with confidence in the era of digital transformation,” said Lee Jong-Sik, Head of KT Corp.’s Infrastructure Research Center. As the company stated, it would share its quantum hybrid technology with operators that provide 5G network services. KT also plans to extend the new tech to sectors requiring tight security, including finance and automotive industries.

Previously, users could only apply quantum security communication by installing separate quantum security terminals with quantum random number generators (QRNG). Notably, KT optimized its newly developed quantum hybrid tech not to use additional quantum security terminals. Since the quantum hybrid technology removes the need for dedicated terminals, users could considerably reduce costs and remarkably improve management.

South Korea’s largest telecommunications company would also continue developing cybersecurity measures for smartphones, especially amid the ever-growing 5G era. Last month, KT developed a highly secure quantum cryptography technology that doesn’t require dedicated terminals for improved security. This recent development encrypts users’ voice data from smartphones, blocking potential tappers and cyber attacks in real-time.
