Quantum computing is advancing rapidly. While it brings exciting opportunities, it also creates a serious risk — it can break the cryptography we rely on today, such as RSA and ECC. This means many existing IoT devices may no longer be secure in the future. To address this challenge, we implemented Post-Quantum Cryptography on the Nuvoton M2354 using our open-source MicroPQC framework. We successfully deployed more than eight PQC algorithms — including NIST standards and South Korean K-PQC — on a Cortex-M23 platform. This proves that even resource-constrained MCUs can become quantum-ready, without sacrificing power efficiency or performance.
