Late Breaking Results: A High-Performance TFHE Bootstrapping Accelerator with Heterogeneous Processing Engines
DescriptionThis paper presents a high-performance programmable bootstrapping (PBS) accelerator for privacy-preserving computation under Torus Fully Homomorphic Encryption (TFHE) scheme. The proposed design features a heterogeneous processing architecture, including a barrel-shifter-based polynomial rotation unit, integer processing elements (PEs) for level decomposition, and complex-number arithmetic PEs for polynomial multiplication. Our proposed design completes one PBS in 47𝜇s, which is over 8×latency reduction while consuming comparable hardware resources compared to state-of-the-art designs.
