Jumping for Bernstein-Yang Inversion

Authors: Li-Jie Jian, Ting-Yuan Wang, Bo-Yin Yang, Ming-Shing Chen


This paper achieves fast polynomial inverse operations specifically tailored for the NTRU Prime KEM on ARMv8 NEON instruction set benchmarking on four processor architectures: Cortex-A53, Cortex-A72, Cortex-A76 and Apple M1. We utilize the jumping divison steps of the constant-time GCD algorithm from Bernstein and Yang (TCHES’19) and optimize underlying polynomial multiplication of various lengths to improve the efficiency for computing polynomial inverse operations in NTRU Prime.
