IoT and Post-Quantum Cryptography: Securing Constrained Devices
IoT devices with 64 KB RAM can use ML-KEM-512. PosQuantum's IoT Shield brings quantum-safe security to ARM Cortex-M, ESP32, RISC-V and more.
IoT devices are particularly vulnerable to the quantum threat. Many have lifecycles of 10-20 years — enough time for quantum computers to become capable of breaking current keys. The "harvest now, decrypt later" strategy is especially relevant for industrial IoT telemetry.
PosQuantum's IoT Shield was designed for resource-constrained devices. ML-KEM-512 requires only 64 KB of RAM for key encapsulation, while ML-KEM-768 (standard) needs 128 KB. Both offer real post-quantum security.
The stack supports 6 platforms: ARM Cortex-M (M4+), ESP32, STM32, Raspberry Pi, RISC-V, and Arduino. Each platform has an optimized SDK — C (Embedded) for constrained devices and Rust (no_std) for systems without allocators.
Features include secure firmware OTA with ML-DSA verification, end-to-end encrypted telemetry with ML-KEM, device provisioning with attestation, mesh networking with PQ keys per link, and immutable audit trail with SHA-3 hash chain.
