Smart Engine for Public Key cryptography

This white paper explains why and how the Smart Engine is ideally applied to Public Key cryptography. It provides more details about the architecture as Baco Silex has implemented it in the BA414E Public Key Crypto Engine

Formally verifying AVX2 rejection sampling for ML-KEM

Formal verification of cryptography comes in many flavours. The levels of abstraction range from high-level protocol designs to machine-level implementations. At each level of abstraction, different target properties and formal verification technologies apply. In this post we look at the latter end of this spectrum and consider a highly-optimized architecture-specific implementation of a core routine of the recent NIST post-quantum standard FIPS-203: Module-Lattice-Based Key Encapsulation Mechanism (ML-KEM)
