HElib

HElib HElib is an open-source Apache License v2.0 software library that implements homomorphic encryption HE. Currently available schemes are the implementations of the Brakerski-Gentry-Vaikuntanathan BGV scheme with bootstrapping and the Approximate Number scheme of Cheon-Kim-Kim-Song CKKS, alon...

A Combined Streaming FPGA Architecture for Client-Side CKKS Encoding and Encryption

Homomorphic encryption allows a computing service to process encrypted data, but the client must first encode and encrypt its inputs. Sharing hardware between floating-point encoding and modular encryption reduces area but requires those transform roles to execute at different times. We present a...
