Aethyr Research has released post-quantum encrypted IoT edge node firmware for ESP32-S3 targets that boots in 2.1 seconds and supports full PQC (Post Quantum Cryptography) handshakes in 35ms. Public-key cryptographic algorithms such as RSA and ECC will soon have to be replaced due to the advance of quantum computers that will be able to crack such encryption within a few hours to days using Shor’s algorithm. While there’s still time, Google recently updated its timeline for post-quantum cryptography migration to 2029, mostly because it’s possible to store data now for an attack once sufficiently powerful quantum computers become available, and the NIST FIPS 203 standard (ML-KEM-768) mandates quantum-resistant security by 2035. The Aethyr Edge Node open-source firmware relies on formally verified ML-KEM-768 (FIPS 203) post-quantum key exchange, BLAKE3 integrity, and XChaCha20-Poly1305 encryption to implement post-quantum encryption to connect to a server over the AethyrWire Protocol (AWP). It’s a building block […]
