Hancomwith, the holding company of Hancom Group, announced on the 20th that it has registered a key technology patent related to post-quantum cryptography (PQC) technology, which defends against quantum computer attacks.
The registered patent is for a technology called 'public key management system using a PQC-based authentication block.' It features the implementation of security and convenience by combining a PQC algorithm that is impossible to decrypt even with a quantum computer with a web authentication method (JWT, JSON Web Token), making it easy and convenient to manage complex certificates.
The patent applies the quantum-resistant cryptography algorithm selected by the National Institute of Standards and Technology (NIST) as the next-generation global standard. Through this, Hancomwith's technology ensures compliance with global standards and secures compatibility and stability that can be utilized across various industries.
Hancomwith has completed the commercialization of the patented technology by applying it to its main security solutions. It supplies the communication segment encryption product 'Hancom XConnect v4.0' and the data encryption software 'Hancom XDB v5.0' to the market, and is also conducting research on lightweight PQC technology optimized for small equipment such as drones and weapons systems through projects with the Korea Research Institute for defense Technology planning and advancement (KRIT).
In the future, Hancomwith plans to develop solutions supporting not only the U.S. standards (NIST) but also the Korean-style quantum-resistant cryptography algorithm (KpqC) in accordance with the government's 'national PQC transition master plan.' Based on this, it intends to expand the application of PQC technology across its entire product line, including common infrastructure security, data and network security, and authentication services, in order to respond to market changes.
Meanwhile, Hancomwith recorded consolidated revenue of 346.6 billion won and an operating profit of 2.5 billion won in the first half of this year, achieving its highest-ever performance. Benefiting from the growth of its subsidiary Hancom Gold Exchange, the digital financial platform business linked to physical assets based on gold is also becoming fully operational, and in the second half, it will promote the issuance of stablecoins through its own platform.
Song Sang-yeob, CEO of Hancomwith, noted, 'We have officially recognized the excellence of the quantum-resistant cryptography technology we have researched for a long time through the patent registration,' and added, 'Along with artificial intelligence (AI) and zero trust, we will continue to invest in quantum-resistant cryptography technology as a core pillar of future information security businesses.'
