SUMMARY:Alchemist: A Unified Accelerator Architecture for Cross-Scheme Ful
 ly Homomorphic Encryption
DESCRIPTION:Research Manuscript\n\nJianan Mu, Husheng Han, Shangyi Shi, Ji
 ng Ye, Zizhen Liu, and Shengwen Liang (Institute of Computing Technology, 
 Chinese Academy of Sciences); Meng Li (Peking University); Mingzhe Zhang (
 Institute of Information Engineering, Chinese Academy of Sciences); Song B
 ian (Beihang University); and Xing Hu, Huaiwei Li, and Xiaowei Li (Institu
 te of Computing Technology, Chinese Academy of Sciences)\n\nThe use of cro
 ss-scheme fully homomorphic encryption (FHE) in privacy-preserving applica
 tions challenges hardware accelerator design. Existing accelerator archite
 ctures fail to efficiently handle hybrid FHE schemes due to the mismatch b
 etween computational demands and hardware resources. We propose a novel ar
 chitecture using a hardware-friendly, versatile low-level operator, i.e., 
 Meta-OP. Our slot-based data management efficiently handles memory access 
 patterns of the meta-op for diverse operations. Alchemist accelerates both
  arithmetic and logic FHE with high hardware utilization rates. Compared t
 o existing ASIC accelerators, Alchemist outperforms with a 29.4× performan
 ce per area improvement for arithmetic FHE and a 7.0× overall speedup for 
 logic FHE.\n\nTopic: Security\n\nKeyword: Hardware Security: Primitives, A
