Raise the Shields: A Modular RISC-V Extension for Post Quantum Cryptography
DescriptionThis work presents a unified RISC-V extension for Post-Quantum Cryptography (PQC) that emphasizes versatility and openness. The design exposes a compact set of custom scalar instructions via the Core-V eXtension Interface (CV-X-IF) and a modular PQ-ALU that accelerates the dominant kernels across hash-, lattice-, and code-based schemes: Keccak processing, randomness sampling, modular and polynomial arithmetic, finite-field operations, and coefficient compression. The system supports standardized algorithms—ML-KEM, ML-DSA, SLH-DSA, and HQC—as well as candidates under evaluation. The full hardware and software stack is released as open source to enable reproducibility and community reuse. We provide ASIC results from post-synthesis characterization in 65 nm CMOS, reporting instruction-cycle counts, along with power and energy estimates for each custom operation.
Overall, the proposed extension delivers a compact (∼48 kGE) and practical path to crypto-agile, energy-efficient PQC on RISC-V while preserving software compatibility and a clean integration into existing cores.
