nQrux® Secure Boot enhances system security by enabling quantum-secure authenticated boot, crucial for verifying the authenticity and integrity of binary images during the processor boot sequence. The protection is rooted in a hybrid digital signature scheme that utilises both ECDSA and ML-DSA. ML-DSA digital signatures are designed to counter threats from quantum computing, while ECDSA provides a reliable fallback to guard against potential vulnerabilities in the newer quantum-resistant algorithms.

Authenticated boot in the quantum era

The protection of nQrux® Secure Boot utilises hybrid model with ECDSA elliptic curves and quantum-secure ML-DSA IP cores from Xiphera’s portfolio. The hybrid sceme utilises the advanced Post-Quantum Cryptography (PQC) with classical elliptic curve cryptography, protecting against the looming quantum threat.
