PQCryptoLib-Embedded

Highly-optimized PQC implementations, capable of running PQC in < 15kb RAM

PQCryptoLib-Emebedded is a versatile, CAVP-compliant version of PQCryptoLib, PQShield’s CMVP-certified library of post-quantum cryptographic algorithms. With its design focused on ultra-small area efficiency, PQCryptoLib-Embedded has been specifically designed for embedded systems, microcontrollers and memory-constrained devices. It could be the first step towards a hardware solution for providing PQC integration to devices already in the field.

The software library is highly configurable at build time, which makes it possible to optimize PQCryptoLib-Embedded for binary size, memory-footprint or performance, and means you can deploy the software without changing the underlying hardware. This makes PQCryptoLib-Embedded an ideal solution for PQC-enablement of brownfield devices that are already deployed in the field, especially when it comes to the provision of quantum-safe TLS. It’s also a consideration for the next generation of devices, as PQCryptoLib-Embedded can be a step towards hardware integration, for example with our PQPlatform products.
