FIQ-PQC03-SW ML-DSA Compact Signature Verification Library

FIQ‑PQC03‑SW is a compact, verification‑only library of ML‑DSA (FIPS 204), the NIST‑standardized post‑quantum digital signature verification algorithm. It is used to verify signatures, optimal for secure boot and authenticated firmware updates on memory‑ and performance‑constrained MCUs and embedded platforms.

As long‑life and connected devices migrate to PQC/hybrid, manufacturers need a practical way to adopt post‑quantum signature verification. FIQ‑PQC03‑SW provides a drop‑in upgrade path from classical secure boot to ML‑DSA-based secure boot, with no hardware changes required.

Built for Embedded, Configurable for High Performance

The library is highly configurable and processor-agnostic, for area and performance tradeoffs across both resource-constrained endpoints and high-throughput environments:

• Low‑cost 32‑bit MCU platforms (ARM Cortex‑M, RISC‑V)
• High-performance CPUs, servers, and HPC/cloud endpoints (ARM64, x86)
• Industrial control systems and SCADA endpoints
• Automotive ECUs with tight memory budgets
• Medical and consumer IoT devices

FIQ‑PQC03‑SW enables NIST‑standardized post‑quantum signature verification in secure boot flows, maintaining exceptional execution speed while minimizing RAM and flash/NVM requirements.
