PQShield has released an updated version of its embedded cryptography library that can run standardised post-quantum cryptography in under 5KB of RAM, a target aimed at microcontroller-based devices with tight memory budgets.

The product, PQMicroLib-Core, is part of the company’s UltraPQ Suite. PQShield is pitching the update as a way for device makers to adopt post-quantum cryptography without redesigning hardware in sectors such as payments, medical wearables, industrial control systems, and networking equipment.

Post-quantum cryptography refers to encryption algorithms designed to resist future attacks from large-scale quantum computers. New standards are moving toward larger keys and more complex operations than many…
