# Cupcake Cupcake is an efficient Rust library for the (additive version of) Fan-Vercauteren homomorphic encryption scheme, offering capabilities to encrypt vectors, add/subtract two encrypted vectors, and rerandomize a ciphertext. ## Requirements Cupcake requires or works with * Mac OS X or Linux ## Installation Add the following line to the dependencies of your Cargo.toml: ``` Cupcake = "0.2.1" ``` ## Building from source ```bash git clone https://github.com/facebookresearch/Cupcake cd cupcake cargo build --release ``` ## Examples Several examples are included in `examples/<name>.rs`, and can be run via `cargo run --example <name>` ## Documentation Documentation on the API can be built from `cargo doc`. ## Benchmarks and Tests We have included benchmarks and tests for both homomorphic operations and underlying arithmetic operations. They can be run using `cargo bench` and `cargo test`. ## Supported parameters Currently, we provide only one set of secure parameter, namely `FV::<Scalar>::default_2048();`. This parameter set has an estimated security level of about 128 bits according to the homomorphic encryption security standards [link](http://homomorphicencryption.org/wp-content/uploads/2018/11/HomomorphicEncryptionStandardv1.1.pdf). Use other parameters at your own risk! With the default parameter set, the plaintext type is vector of `u8` with a fixed length 2048. ## References - [The Fan-Vercauteren scheme](http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.400.6346&rep=rep1&type=pdf) See the [CONTRIBUTING](CONTRIBUTING.md) file for how to help out. ## License Cupcake is MIT licensed, as found in the LICENSE file.
