HERA: A Bandwidth-efficient Accelerator for Fully H omomorphic E nc r yption on HBM-enabled FPG A
Abstract
Fully Homomorphic Encryption (FHE) enables privacy-preserving computation on encrypted data. However, it incurs massive computation and DRAM traffic overheads, making hardware acceleration essential. Existing FPGA-based solutions offer limited exploration of bandwidth utilization and memory optimizations, leaving room for further performance improvements.
