Small Footprint PQC Library for Embedded Security
PQShield, the market leader in post-quantum cryptography (PQC), has announced major upgrades to its UltraPQ Suite, delivering what it states is the smallest-ever PQC solution for the embedded market, the world’s first full-stack post-quantum TLS, and new protections against physical attacks on embedded devices.
The announcement was made at Embedded World in Nuremberg, one of the world’s leading events for embedded systems and IoT security.
Ultra-Compact Embedded Cryptography
At the centre of the update is PQMicroLib-Core, PQShield’s ultra-compact cryptographic library designed for highly constrained devices.
The upgraded version delivers quantum-resistant cryptography with a footprint of less than 5KB, making it one of the leanest professional-grade PQC implementations available for embedded environments.
This breakthrough enables manufacturers to integrate future-proof cryptography into devices with extremely limited memory, including:
- Sensors
- Industrial controllers
- Secure elements
- Next-generation IoT infrastructure
Supporting Real-World Embedded Use Cases
This advancement ensures that even the most resource-constrained devices can implement robust security. With a small footprint PQC library, organizations can now align security with the practical limitations of modern hardware.
