SUMMARY:LPA-NTT: Efficient Lightweight Polynomial Multiplication Accelerat
 or with Hybrid NTT Algorithm
DESCRIPTION:Sizhao Li and Wenqi Zhang (Harbin Engineering University), Tia
 ntai Deng and Kaiyuan Yang (University of Sheffield), and Xing Huang (Harb
 in Engineering University)\n\nPolynomial multiplication, a core component 
 of lattice-based cryptography, has demonstrated impressive performance for
  lattice cryptography chips. However, costly Number Theoretic Transform (N
 TT) make efficient and flexible hardware design to be extremely challengin
 g, particularly for ASIC/FPGA-based hardware acceleration solutions that o
 ften face difficulties with high resource consumption and low computationa
 l efficiency. In this paper we propose LPA-NTT, which adheres to the same 
 principles applicable to various post-quantum cryptography (PQC) algorithm
 s and operates under very strict power constraints. Despite these limitati
 ons, our approach demonstrates state-of-the-art computing performance for 
 complex applications like NTT by eliminating pre-computing operation and n
 ear-memory mapping scheme, thereby reducing computational dimensions and d
 ata relocate. Our experimental results show that LPA-NTT outperforms previ
 ous best NTT accelerators by 14.8%~36.7% in terms of resource consumption,
  while also significantly reducing area and power overhead.\n\nTracks: DES
