FalconSign: An Efficient and High-Throughput Hardware Architecture for Falcon Signature Generation

Abstract: Falcon is a lattice-based quantum-resistant digital signature scheme renowned for its high signature generation/verification speed and compact signature size. The scheme has been selected to be drafted in the third round of the post-quantum cryptography (PQC) standardization process due to its unique attributes and robust security features. Despite its strengths, there has been a lack of research on hardware acceleration, primarily due to its complex calculation flow and floating-point operations, which hinders its widespread adoption. To address this issue, we propose FalconSign, a high-performance, configurable crypto-processor designed to accelerate Falcon signature generation on FPGA/ASIC through algorithmhardware co-design. Our approach involves a new scheduling flow and architecture for Fast-Fourier Sampling to enhance computing unit reuse and reduce processing time. Additionally, we introduce several optimized modules, including configurable randomness generation units, para.... https://ojs.ub.rub.de/index.php/TCHES/article/view/11927
