A Comparison of the Homomorphic Encryption Libraries HElib, SEAL and FV-NFLlib

International audienceFully homomorphic encryption has considerably evolved during the past 10 years. In particular, the discovery of more efficient schemes has brought the computational complexity down to acceptable levels for some applications. Several implementations of these schemes have been publicly released, enabling researchers and practitioners to better understand the performance properties of the schemes. This improved understanding of the performance has led to the discovery of new potential applications of homomorphic encryption, fuelling further research on all fronts.In this work, we provide a comparative benchmark of the leading homomorphic encryption libraries HElib, FV-NFLlib, and SEAL for large plaintext moduli of up to 2048 bits, and analyze their relative performance
