IDEMIA and KT Put NIST and KpqC Post-Quantum Algorithms on One SIM for South Korea's Defense Pilot, 26 October 2026: What a Secure-Element Root of Trust Changes for Tactical Endpoints

IDEMIA Secure Transactions said on 26 October 2026 that it is implementing both the NIST algorithms and South Korea's KpqC algorithms on a quantum-resistant SIM for KT's post-quantum pilot for the Ministry of National Defense and the Army Information and Communication School, covering drones and ground control stations, CCTV and video storage, user PCs and 5G segments. This post reads the announcement as a defensive post-quantum cryptography capability: what a secure-element hardware root of trust would let a force do with tactical endpoints it already owns, why two algorithm families on one chip is the point, and what validation, conformance and performance evidence still separates a vendor release from a program office.
