PQShield has introduced a lightweight post-quantum cryptography library for embedded systems, boasting a memory footprint of under 5KB. This upgrade to the UltraPQ Suite, known as PQMicroLib-Core, enables quantum-resistant cryptography and TLS support for resource-constrained devices without requiring hardware modifications. The library also incorporates protections against physical attacks, including differential power analysis and fault injection, which are particularly relevant given the larger key sizes used in post-quantum cryptography. By providing a software-based solution, PQShield's library allows for the secure deployment of post-quantum cryptography in embedded devices, addressing a critical need as the threat of quantum computing to classical cryptography grows1. This development is significant for practitioners, as it underscores the increasing urgency of migrating to post-quantum cryptography, highlighting the need for proactive planning to ensure the long-term security of embedded systems.
