Post-quantum cryptography for embedded and IoT: secure boot, TLS and OTA (opens in new tab)

Post-quantum cryptography is no longer just a research topic. It is starting to affect the way embedded teams design TLS, secure boot, OTA, firmware signing, device identity and long-term product maintenance. NIST has finalized the first post-quantum standards. OpenSSL 3.5 now includes ML-KEM, ML-DSA and SLH-DSA support. The European roadmap points toward a coordinated transition, and embedded vendors are already moving PQC into MCU and firmware workflows. For connected products that may stay...
