nQrux® Hardware Trust Engines
with QDID PUF

Quantum-resilience and immutable device identity for cryptographic hardware modules.

nQrux® Hardware Trust Engines, together with QDID PUF (Physically Unclonable Function), provide quantum-resistance and immutable device identity for cryptographic hardware modules.

Xiphera’s nQrux® Hardware Trust Engines, including implementations of Post-Quantum Cryptography (PQC), offer customisable cryptographic security modules, isolating cryptographic operations and application data into secure hardware elements. QDID PUF from Crypto Quantique generates quantum-derived, secure, unclonable identities based on manufacturing variations unique to each semiconductor chip. The PUF, alongside other cryptographic primitives, forms the essential hardware root-of-trust in security implementations.

The combination of nQrux® Hardware Trust Engines and QDID PUF provides the adaptability and upgradeability required to secure the connected devices. As many industrial and governmental entities recommend implementing quantum-resilient hardware now, upgrading critical components with quantum-resilient nQrux® IP cores and QDID PUF protects the identities and core security of hardware devices into the foreseeable future.
