TFHE (Fast Fully Homomorphic Encryption over the Torus)

‍TFHE was an open-source library for Fully Homomorphic Encryption (FHE), distributed under the terms of the Apache 2.0 license. The underlying scheme is described in best paper of the IACR conference Asiacrypt 2016: “Faster fully homomorphic encryption: Bootstrapping in less than 0.1 seconds”, presented by Ilaria Chillotti, Nicolas Gama, Mariya Georgieva and Malika Izabachène. Below is a brief history of the TFHE scheme, releases and latest improvements.
‍‍

Check out the latest TFHE implementation: TFHE-rs on Github.

‍‍TFHE-rs is a pure Rust implementation of TFHE for booleans and integers FHE arithmetics over encrypted data. The library is meant for developers and researchers who want full control over what they do with TFHE, while not concerning themselves with the low level implementation.

TFHE-rs aims at being the new reference implementation for TFHE by extending the usual scheme possibilities, including up-to-date security parameters and state-of-the-art features.
