fhe-no-std

This is the no-std version of fhe.rs. It is still WIP and please do NOT use it in production.

The library features:

  • An implementation of a RNS-variant of the Brakerski-Fan-Vercauteren (BFV) homomorphic encryption scheme;
  • Performances comparable or better than state-of-the-art libraries in C++ and Go.

Warning fhe.rs is a beta library, and should be considered unstable with potential breaking API changes until version 1.0.0 is released!

Note This library is not related to the tfhe-rs library (a.k.a. concrete), Zama's fully homomorphic encryption in Rust, available at tfhe.rs.

fhe.rs crates

fhe.rs is implemented using the Rust programming language. The ecosystem is composed of four public crates (packages):

  • fhe crate version fhe: This crate contains the implementations of the homomorphic encryption schemes;
  • fhe-math crate version fhe-math: This crate contains the core mathematical operations for the fhe crate;
  • fhe-traits crate version fhe-traits: This crate contains traits for homomorphic encryption schemes;
  • fhe-util crate version fhe-util: This crate contains utility functions for the fhe crate.

Installation

To install, add the following to your project's Cargo.toml file:

[dependencies]
fhe = "0.1.0-beta.8"
fhe-traits = "0.1.0-beta.8"

Minimum supported version / toolchain

Rust 1.73 or newer.

⚠️ Security / Stability

The implementations contained in the fhe.rs ecosystem have never been independently audited for security. Additionally, no promise on the API and ABI stability will be made until version 1.0.0 of the crates.

Use at your own risk.
