IDEMIA Secure Transactions is working with KT on a South Korean government-backed pilot that will test post-quantum cryptography on a SIM-based smart-card platform for defense communications. The pilot also covers PCs, surveillance systems, drones and 5G networks; the claimed first Korean smart-card implementation of KpqC algorithms remains subject to final validation.
IDEMIA Secure Transactions is collaborating with South Korean mobile operator KT to test post-quantum cryptography on a SIM-based smart-card platform in a government-backed pilot aimed at protecting defense communications. The project will implement NIST-standardized and Korean algorithms on IDEMIA’s Quantum-Resistant SIM, while KT’s broader trial examines post-quantum security across defense systems and 5G networks.
The pilot is South Korea’s 2026 Post-Quantum Cryptography (PQC) Pilot Conversion Project, organized by the Ministry of Science and ICT and the Korea Internet & Security Agency. IDEMIA says it is putting both internationally standardized algorithms from the U.S. National Institute of Standards and Technology and Korean PQC algorithms onto its secure SIM platform. The project is intended to test whether these cryptographic operations can be run within a tamper-resistant secure element used in mobile connectivity.
According to the announcement, KT’s wider pilot is being conducted for the Ministry of National Defense and the Army Information and Communication School. Its planned scope includes smart-unit platforms and user PCs, CCTV and video-storage systems, drones and ground-control systems, and 5G network environments. The pilot is intended to assess performance and practical applicability in these settings; the announcement does not report results from those tests.
IDEMIA describes the SIM as a hardware root of trust that can generate and protect credentials and perform cryptographic operations. The company says its PQC-focused SIM and eSIM designs are intended to handle the greater processing and memory demands of post-quantum algorithms within the secure element. The announced implementation is a project under test, not evidence that the technology has already been deployed across South Korean defense systems.
Testing PQC Inside Defense SIMs
The project tests whether post-quantum cryptography can be integrated into a component already used in mobile devices, rather than requiring every connected device to be redesigned. If the approach performs as intended, a SIM or eSIM secure element could provide a protected place to manage cryptographic keys and operations for communications involving mobile and connected equipment. That possibility matters for defense networks, where systems such as drones, surveillance equipment and mobile devices may need to exchange sensitive information.
The work also addresses crypto-agility: the ability to change algorithms as technical standards and government requirements develop. Supporting Korean and NIST-standardized algorithms in the same platform is presented by IDEMIA as a way to accommodate different standards without a full device redesign. Whether that flexibility works across the pilot’s systems, and what performance costs it may carry, will depend on testing.
Post-quantum cryptography is intended to protect information against future threats from quantum computers capable of undermining some widely used public-key cryptographic methods. The announcement does not say that such a computer can currently break the systems in question. The immediate relevance is preparation: government and defense organizations are evaluating ways to update sensitive infrastructure before cryptographic standards or threat capabilities change.

South Korea’s 2026 PQC Pilot
The announcement places the collaboration within a broader South Korean government effort to evaluate PQC across critical infrastructure. MSIT and KISA organize the pilot, with KT leading the defense-oriented work described by the companies. IDEMIA’s role is narrower: implementing the algorithms on its Quantum-Resistant SIM-equipped smart-card platform.
The company says the project could produce the first implementation of KpqC algorithms on a smart-card platform in Korea, but explicitly makes that outcome subject to final validation. The announcement does not identify the validation criteria, name the specific algorithms, or provide a timetable for the final assessment. The claim should therefore be read as an expected milestone, not a completed result.
SIMs and eSIMs are commonly associated with identifying subscribers and enabling cellular connectivity. IDEMIA’s announcement argues that secure elements in these products can also support cryptographic services for connected devices and critical infrastructure. The pilot will test that proposition in a defense setting; it does not establish that SIM-based security will replace other protections used in those systems.
“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 Results Remain Pending
The announcement provides no test results, performance measurements or deployment decisions. It is not clear when the pilot’s evaluation will be completed, how it will measure security and operational performance, or whether the SIM implementation will be adopted beyond testing. IDEMIA’s anticipated Korean smart-card milestone depends on final validation, which has not been reported.
The source also does not specify which NIST-standardized or Korean algorithms are being implemented, how the SIM and eSIM versions will differ, or how the platform will connect with the other systems in KT’s pilot. The range of equipment named in the announcement describes the broader evaluation; it does not confirm that every system will use IDEMIA’s SIM technology.
Pilot Testing And Validation
The next stated step is for KT and the other project participants to assess post-quantum cryptography across the listed defense and network environments. IDEMIA’s smart-card implementation will need to complete final validation before the company’s expected KpqC milestone can be treated as confirmed. The announcement gives no specific dates for results or for any subsequent deployment decision.
Readers should look for details on validation outcomes, the algorithms tested, and whether the approach meets the operational needs of the Ministry of National Defense and the Army Information and Communication School. Until those findings are released, the collaboration is best understood as a government-backed pilot, not a confirmed rollout.
Key Questions
What are IDEMIA 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 South Korea’s 2026 PQC pilot.
Which systems are included in KT’s wider pilot?
The announced scope includes smart-unit platforms, user PCs, CCTV and video-storage systems, drones and ground-control systems, and 5G network environments.
Has the SIM platform been validated or deployed?
The announcement reports an implementation being tested, not a completed validation or broad deployment. IDEMIA says the expected Korean KpqC smart-card milestone is subject to final validation.
What does post-quantum cryptography mean here?
It refers to cryptographic algorithms designed to resist attacks from future quantum computers. The pilot is evaluating their use in defense communications; the announcement does not claim that quantum computers currently pose a demonstrated ability to break the systems being tested.
