IDEMIA Secure Transactions is working with KT on a South Korean government-backed pilot testing post-quantum cryptography for defense communications. The work puts NIST-standardized and Korean algorithms on a Quantum-Resistant SIM platform; a potential first Korean smart-card implementation of KpqC algorithms remains subject to final validation.
IDEMIA Secure Transactions (IST) is collaborating with South Korean telecom operator KT on a government-backed pilot testing post-quantum cryptography for defense communications. IST is implementing NIST-standardized and Korean algorithms on a Quantum-Resistant SIM platform, while KT’s wider project assesses the technology across defense systems and 5G environments.
The project is South Korea’s 2026 Post-Quantum Cryptography Pilot Conversion Project, organized by the Ministry of Science and ICT and the Korea Internet & Security Agency. KT is leading the broader pilot, which is being conducted for the Ministry of National Defense and the Army Information and Communication School. IST’s contribution focuses on fitting post-quantum cryptographic capabilities into a SIM and smart-card platform.
According to the project announcement, the Quantum-Resistant SIM is intended to provide a hardware root of trust for secure communications by protecting credentials and cryptographic operations. The platform is designed to support both international NIST-standardized algorithms and Korean post-quantum algorithms. IST says its dedicated SIM and eSIM approach is intended to handle the greater processing and memory demands of these algorithms in a tamper-resistant environment.
KT’s pilot will assess post-quantum security across smart-unit platforms and user PCs, CCTV and video storage systems, drones and their ground-control systems, and 5G network environments. The stated purpose is to test performance and applicability in operational settings. The announcement says the project is expected to produce Korea’s first implementation of KpqC algorithms on a smart-card platform, but that outcome is subject to final validation.
Testing Quantum-Safe Defense Communications
The project is a practical test of how post-quantum cryptography could be introduced into systems that support military communications and connected defense equipment. A SIM-based secure element could provide a protected place to manage credentials and cryptographic operations while devices connect to mobile networks or other infrastructure. The pilot’s inclusion of PCs, surveillance systems, drones and 5G environments makes the work broader than a test of a single handset or network component.
Its emphasis on crypto-agility also addresses a deployment challenge: algorithms and standards may change as security requirements develop. The project is designed to support both NIST-standardized and Korean algorithms within one secure-element environment. If validated, that approach could offer a way to update cryptographic capabilities without redesigning every connected device. The announcement describes the intended use and scope; it does not report completed performance results or confirm deployment in operational defense systems.

Korea’s 2026 PQC Pilot
Post-quantum cryptography refers to cryptographic methods designed to resist attacks from future quantum computers. Governments and organizations are evaluating such methods because existing public-key cryptography may need to be replaced or updated as computing capabilities change. The source announcement does not claim that a quantum computer has broken the systems covered by this pilot; it presents the project as preparation for emerging cryptographic threats.
South Korea’s project brings together government agencies, KT and IST to test the technology across multiple types of defense infrastructure. IST says the work builds on its broader post-quantum roadmap within the IDEMIA SPHERE cybersecurity suite. SIM and eSIM technologies are widely associated with telecom authentication; this project explores their use as secure elements for additional cryptographic services in government, defense and connected-device applications.
“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 Still Pending
The announcement does not provide test results, performance measurements, or a completion date for the pilot. It also does not detail which specific NIST-standardized algorithms or Korean algorithms are being implemented, how the systems will be evaluated, or what operational criteria would count as successful validation.
The claim that the project is expected to deliver Korea’s first KpqC implementation on a smart-card platform is explicitly conditional on final validation. The source does not identify the validation process or say when it will conclude. It also remains unclear whether the pilot will lead to procurement, wider deployment, or changes to defense communications systems.
Pilot Testing and Final Validation
The next reported stage is the pilot’s assessment of performance and applicability across the listed defense and network environments. The announcement gives no schedule for publishing results or completing the work. Any claim about a Korean smart-card first will depend on the project’s final validation, and broader adoption would require decisions beyond the collaboration itself.
Key Questions
What are IDEMIA Secure Transactions and KT doing?
They are collaborating on South Korea’s 2026 post-quantum cryptography pilot. IST is implementing NIST-standardized and Korean algorithms on a Quantum-Resistant SIM platform for secure communications.
Which systems are included in KT’s wider pilot?
The announced scope includes smart-unit platforms, PCs, CCTV and video storage, drones and ground-control systems, and 5G environments. The project is intended to assess performance and applicability across these settings.
Has the project confirmed Korea’s first KpqC smart-card implementation?
No. The announcement says the project is expected to deliver that result, subject to final validation. It does not report that validation as complete.
Have the partners released results or a deployment schedule?
The announcement provides no performance results, completion date, or deployment plan. It describes the pilot’s intended scope and says testing will assess applicability in operational conditions.
