We’re excited to announce that PQMicroLib-Core now supports PSA Certified Crypto API integration.

It’s our goal to make post-quantum cryptography accessible to even the smallest of devices, in as little as 5 KB RAM. This integration helps bridge the gap between high-security quantum resistance and industry-standard embedded development.

For developers in the embedded space, it’s a game-changer. By integrating PQMicroLib-Core with PSA Certified Crypto API, you can use a trusted, portable interface for cryptographic services across different hardware.

PQMicroLib-Core is optimizable for resource-constrained MCUs where every byte of memory counts. In addition, it includes optional side channel protection for resistance against attacks such as DPA, and it’s been designed with crypto-agility in mind.

Whether building industrial sensors, secure boot systems, or remote devices, PQMicroLib-Core allows manufacturers to update brownfield devices to quantum safe-standards with a simple software update, removing the need for expensive hardware replacement.
