Implementing Post-Quantum Cryptography in Hardware-Accelerated Roots of Trust (E30a)
Low-level hardware roots of trust perform critical roles in various devices. Their services include secure boot and attestation, leveraging asymmetric cryptography, which requires updates to support newly standardized post-quantum algorithms. Long hardware lifecycles present a unique challenge for data centers transitioning to quantum resistance, an issue that demands immediate attention.
This talk describes how diverse hardware roots of trust are adopting post-quantum algorithms in their silicon. It examines OpenTitan and Caliptra, two hardware roots of trust that can be integrated into various platforms and are driving the adoption of post-quantum algorithms such as ML-DSA and SPHINCS+.
In addition to discussing overall design, the talk addresses performance tuning and side-channel resistance, providing insights into the adoption of quantum-resistant cryptographic systems.
