IDEMIA Secure Transactions is working with KT on a South Korean government-backed pilot that tests post-quantum cryptography on a SIM-based smart-card platform for defense communications. The broader pilot will assess post-quantum security across devices and networks; the claimed first Korean smart-card implementation of KpqC algorithms depends on final validation.
IDEMIA Secure Transactions is collaborating with South Korean operator KT on a government-backed pilot to test post-quantum cryptography for defense communications, including algorithms implemented on a Quantum-Resistant SIM platform. The work is part of South Korea’s 2026 Post-Quantum Cryptography Pilot Conversion Project, organized by the Ministry of Science and ICT and the Korea Internet & Security Agency; a potential first Korean implementation of KpqC algorithms on a smart-card platform remains subject to final validation.
In the collaboration, IDEMIA Secure Transactions (IST) is implementing NIST-standardized and Korean post-quantum algorithms on a SIM-equipped smart-card platform. The company says its dedicated post-quantum SIM and eSIM are designed to handle the algorithms’ higher processing and memory demands within a secure, tamper-resistant environment. The announcement describes the platform as a way to protect credentials and cryptographic operations at the device’s secure-element level.
KT is leading a broader pilot conducted for South Korea’s Ministry of National Defense and the Army Information and Communication School. According to the announcement, the pilot is intended to evaluate post-quantum cryptography across smart-unit platforms and user PCs, CCTV and video storage systems, drones and ground-control systems, and 5G network environments. It will assess performance and applicability in operational conditions; the source does not report test results.
IST says the project is expected, subject to final validation, to deliver the first implementation of KpqC algorithms on a smart-card platform in Korea. That is a forecast in the company’s announcement, not a completed or independently confirmed result. The project is also intended to demonstrate support for international and Korean algorithms within one secure-element environment.
Testing Quantum-Ready Defense Communications
The pilot puts post-quantum security into a practical defense setting rather than limiting the work to algorithm research. If the approach performs as intended, a SIM or eSIM secure element could help protect keys and cryptographic operations in connected equipment while reducing the need to redesign entire devices. The pilot’s stated scope—from PCs and surveillance systems to drones and 5G—also reflects how defense communications depend on a range of connected systems.
The collaboration’s focus on both NIST-standardized and Korean algorithms addresses the need for systems that can adapt as standards and national requirements change. IST describes that adaptability as crypto-agility. The announcement establishes that the algorithms are being implemented for testing, but does not show that the platform has passed operational evaluation or is ready for broad deployment.

South Korea’s 2026 PQC Pilot
Post-quantum cryptography refers to cryptographic methods designed to resist attacks from future quantum computers. The concern is that advances in quantum computing could weaken some widely used public-key cryptography, creating a need to update systems that protect communications and sensitive data. The source describes South Korea as accelerating post-quantum security work across critical sectors, but provides no further timeline or national deployment targets.
The 2026 pilot is organized by the Ministry of Science and ICT and KISA, with KT playing a leading role in the defense-focused work. IDEMIA’s announcement situates the SIM project within its broader post-quantum roadmap and cybersecurity offering. The immediate development is a pilot implementation and assessment, not a report that defense systems have already been converted to post-quantum protection.
“At IDEMIA Secure Transactions, we see the transition to post-quantum security as a strategic imperative to safeguard digital trust for the long term.”
— Fabien Jautard, executive vice president of Connectivity Services at IDEMIA Secure Transactions
Validation and Deployment Still Pending
The announcement does not provide a timetable for completing the pilot, technical performance measurements, or results from testing in defense operating conditions. It also does not specify which particular NIST-standardized algorithms or Korean algorithms are being implemented, nor detail how the pilot will measure security, processing demands, or compatibility across its listed systems.
The expected KpqC smart-card milestone is explicitly subject to final validation. The source does not name the validation process, responsible evaluator, or criteria for confirming the claimed first. It remains unclear whether successful testing would lead to procurement or wider deployment, and no independent assessment of the platform is included.
Pilot Testing and Final Validation
The next reported steps are testing the SIM-based implementation and evaluating post-quantum security across the defense environments in KT’s pilot. Final validation will determine whether the project can support its stated KpqC smart-card milestone. The companies and organizers have not provided dates for results or a decision on any subsequent rollout.
Key Questions
What are IDEMIA Secure Transactions and KT testing?
They are testing NIST-standardized and Korean post-quantum algorithms on IDEMIA’s Quantum-Resistant SIM-equipped smart-card platform as part of a South Korean government-backed pilot.
Which defense systems are included in the broader pilot?
The announced scope includes smart-unit platforms, user PCs, CCTV and video storage, drones and ground-control systems, and 5G networks. The pilot is intended to assess performance and applicability in operational conditions.
Has the project already demonstrated a Korean first?
No completed result is reported. IDEMIA says a first implementation of KpqC algorithms on a Korean smart-card platform is expected, but it is subject to final validation.
When will the pilot results be released?
The announcement does not give a completion date or results schedule. It also does not say whether testing will lead to wider deployment.
