[Edaily Reporter Ahn Yu-ri] #RaonSecure announced on the 4th that it has signed a contract with KDB Life Insurance to supply post-quantum cryptography (PQC) solutions, securing its first reference in the financial industry.

The company is currently in the process of finalizing new quantum security contracts with more than 10 major domestic banks, securities firms, credit card companies, and insurance companies in addition to KDB Life Insurance, and is also in discussions regarding adoption by public institutions. As demand for quantum security rapidly expands across all industries, order intake centered on the financial sector is gaining momentum.

RaonSecure’s “Key# Crypto” is a software-based cryptographic module solution that allows for the easy implementation of post-quantum cryptography to defend against attacks from quantum computers. Cryptographic modules serve as the core infrastructure of security systems and can be flexibly applied to numerous services and various security domains.

In addition, RaonSecure provides comprehensive security solutions based on PQC, including authentication, session encryption, digital signatures, and input security. This allows client companies to swiftly transition to a quantum-secure framework while minimizing the burden of modifying existing systems.

Another key feature is support for the "hybrid PQC" approach, which maintains compatibility with RSA-based public-key cryptosystems. Since it allows for phased implementation without compromising operational stability, it ensures flexibility even for financial institutions and public agencies with complex system environments.

RaonSecure is one of the first companies in the information security industry to complete the commercialization of PQC. The company has proactively established a technical framework that supports both the Korean Post-Quantum Cryptography (KpqC) and U.S. National Institute of Standards and Technology (NIST) standard algorithms, thereby securing the capabilities for PQC commercialization.

Furthermore, the company has completed compliance verification under the National Intelligence Service’s Cryptographic Module Verification Program (KCMVP) and obtained Federal Information Processing Standard (FIPS 140-2) certification, thereby meeting domestic and international financial security regulatory requirements.

In terms of field implementation experience, the company has accumulated extensive expertise in quantum security since 2024, including the integration and commercialization of NIST’s CRYSTALS-Kyber-based algorithms into its electronic signature solution, ‘Key#Biz,’ and its end-to-end encryption solution, ‘Key#Wireless.’

Last year, the company was selected as the lead firm for the healthcare sector in the Ministry of Science and ICT and the Korea Internet & Security Agency (KISA)’s ‘Quantum-Resistant Cryptography Pilot Transition Support Project.’ It recently completed a pilot project at Severance Hospital, applying PQC-based end-to-end encryption security to Korea’s first open medical data platform. As the company expands its technological foundation to meet PQC demand across key sectors such as public services, healthcare, and finance, revenue growth in quantum security is expected to accelerate.

The market environment is also favorable. As advancements in quantum computing technology accelerate, regulatory changes both domestically and internationally are serving as catalysts for the widespread adoption of PQC. The government recently passed an amendment to the Quantum Technology Industry Act at a Cabinet meeting, establishing mandatory requirements for public institutions to build quantum security systems and providing a legal basis for preemptive security inspections in the defense, telecommunications, and financial sectors.

The urgency to respond to security threats is also increasing. As “Harvest Now, Decrypt Later (HNDL)” attacks—where encrypted data is collected in advance and decrypted later using quantum computers—emerge as a realistic threat, the need for quantum security measures is rapidly spreading, particularly among financial and public institutions, ahead of the advent of the quantum computing era.

RaonSecure anticipates that demand for PQC adoption will expand across all security domains, including authentication, digital signatures, end-to-end encryption, and Identity and Access Management (IAM). The company plans to target a wide range of sectors, from the highly regulated financial and public sectors to telecommunications, platforms, e-commerce, healthcare, and manufacturing—all of which handle large volumes of user data.

Lee Jung-ah, CEO of RaonSecure, stated, “With the advancement of quantum computing signaling an impending overhaul of existing information security systems, preemptive action is necessary across all industries.” She added, “RaonSecure will reliably support our clients’ adoption of quantum security and establish itself as a trusted partner leading the domestic PQC market.”
