PQMicroLib-Core

PQMicroLib‑Core is a compact bare‑metal PQC library that runs in as little as 5 KB of RAM, with an option for DPA‑resistant variants.

Derived from PQShield’s CMVP‑certified PQCryptoLib‑Core, it is CAVP‑Ready and built for embedded and RTOS‑based systems.

It supports the latest standardized algorithms, including ML‑KEM (FIPS 203), ML‑DSA (FIPS 204), SLH‑DSA (FIPS 205), XMSS, LMS, SHA‑2, SHA‑3, and DRBG.

Key Benefits:

Multiple optimized implementations for diverse performance and footprint needs
Hardware‑accelerated extensions and a documented API for mainstream devices
Thorough functional and security validation (CAVP‑Ready)
Supports PQC CNSA 2.0 algorithms
Runs on any platform with a C compiler, with integration support available

Common Use Cases:

Secure Boot and Secure Firmware Updates (OTA)
Device/user authentication and remote attestation
Migration from classical crypto to PQC (incl. TLS & key exchange)
Secure key management and provisioning for devices
Protection of data at rest: confidentiality, integrity, authenticity
