Conclusions

In this paper, we propose GSR-NTT and demonstrate that K-NTT, H-NTT, and G3-NTT are specific instances of GSR-NTT. We introduce a succinct methodology for complexity analysis, and utilize our GSR-NTT to accelerate polynomial multiplications in NTTRU and power-of-three cyclotomic rings.
