Side Channel Countermeasures for the Adams Bridge PQC Accelerator

Learn about hardware security countermeasures in this technical presentation from Microsoft engineers Emre Karabulut and Kiran Upadhyayula, who demonstrate how to protect post-quantum cryptography (PQC) implementations against side-channel attacks. Explore the development of robust security measures for the Adams Bridge accelerator project, which implements NIST-selected PQC algorithms including CRYSTALS-Dilithium ML-DSA. Discover comprehensive threat modeling techniques, masking and hiding strategies, constant-time execution approaches, and methods for balancing resource usage, area, latency, power consumption and performance while maintaining strong protection. Examine how these security features are integrated into Caliptra, an open-source root of trust platform, to create resilient hardware implementations of next-generation cryptographic algorithms.
