CryptoLight: An Electro-Optical Accelerator for Fully Homomorphic Encryption (2211.13780v2)
Published 24 Nov 2022 in cs.CR and cs.AR
Abstract: Fully homomorphic encryption (FHE) protects data privacy in cloud computing by enabling computations to directly occur on ciphertexts. To improve the time-consuming FHE operations, we present an electro-optical (EO) FHE accelerator, CryptoLight. Compared to prior FHE accelerators, on average, CryptoLight reduces the latency of various FHE applications by >94.4% and the energy consumption by >95%
