CryptoLight: An Electro-Optical Accelerator for Fully Homomorphic Encryption
PROCEEDINGS OF THE 17TH ACM INTERNATIONAL SYMPOSIUM ON NANOSCALE ARCHITECTURES, NANOARCH 2022(2022)
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 by >95%
