ePrint Report: Number-Theoretic Transform Architecture for Fully Homomorphic Encryption from Hypercube Topology

Jingwei Hu, Yuhong Fang, Wangchen Dai

This paper introduces a high-performance and scalable hardware architecture designed for the Number-Theoretic Transform (NTT), a fundamental component extensively utilized in lattice-based encryption and fully homomorphic encryption schemes.


The underlying rationale behind this research is to harness the advantages of the hypercube topology. This topology serves to significantly diminish the volume of data exchanges required during each iteration of the NTT, reducing …
