Hancom With Registers Patent for Post-Quantum Cryptography Technology

Hancom With Completes Commercialization of Post-Quantum Cryptography
Secures Patent for Core PQC Technology to Defend Against Quantum Computer Attacks

Hancom With, the holding company of Hancom Group, announced on August 20 that it has completed the registration of a core patent related to 'Post-Quantum Cryptography (PQC)', a security technology designed to defend against quantum computer attacks.

The registered patent covers a "Public Key Management System Using PQC-Based Authentication Block" technology. By combining a PQC algorithm, which cannot be decrypted even by quantum computers, with a simple and easily expressible web authentication method (JWT), the company has achieved both security and convenience, enabling the easy management of complex PQC-based digital certificates.

The patent incorporates a post-quantum cryptography algorithm selected by the U.S. National Institute of Standards and Technology (NIST) as the next-generation global standard.

Hancom With has already commercialized this patented technology by applying it to its main security solutions. It is currently being supplied to the market through its communication channel encryption product 'Hancom XConnect v4.0' and its data encryption software 'Hancom XDB v5.0'. In addition, the company has secured a project from the Agency for Defense Development and is expanding the scope of its technology by conducting research on lightweight PQC optimized for small embedded devices such as drones and weapon systems.

Going forward, Hancom With plans to develop a system that supports not only the U.S. standard (NIST) but also the 'Korean Post-Quantum Cryptography Algorithm (KpqC)' in line with the government's 'National PQC Transition Master Plan'. The company aims to proactively respond to market changes by expanding the application of PQC technology across its entire range of security products, including common infrastructure security, data and network security, and security authentication services.

Song Sangyeop, CEO of Hancom With, stated, "The official registration of this patent is a formal recognition of the excellence of our post-quantum cryptography technology, which we have been researching for a long time." He added, "Along with artificial intelligence (AI) and zero trust, we will position post-quantum cryptography technology as a core pillar of our future information security business and continue to invest in strengthening our technological competitiveness."
