CryptoLight: An Electro-Optical Accelerator for Fully Homomorphic Encryption. (arXiv:2211.13780v1 [cs.CR])
cs.CR updates on arXiv.org arxiv.org
Fully homomorphic encryption (FHE) protects data privacy in cloud computing
by enabling computations to directly occur on ciphertexts. Although the speed
of computationally expensive FHE operations can be significantly boosted by
prior ASIC-based FHE accelerators, the performance of key-switching, the
dominate primitive in various FHE operations, is seriously limited by their
small bit-width datapaths and frequent matrix transpositions. In this paper, we
present an electro-optical (EO) FHE accelerator, CryptoLight, to accelerate FHE
operations. Its 512-bit datapath supporting 510-bit residues greatly …
