Securing Firmware OTA Updates with Post-Quantum Cryptography

​This hands-on workshop explores how quantum computing could impact the cryptographic trust mechanisms used to secure firmware and over-the-air updates. Participants will learn the fundamentals of post-quantum cryptography. understand the risks to long-lived devices and digital signatures, and work through a practical firmware-signing lab using ECDSA P-256 and ML-DSA-44, Through signing, verification and tampering exercises, the workshop demonstrates the practical implications of migrating to quantum-resistant cryptography and highlights the importance of crypto agility, trust-anchor management and early PQC migration planning.
