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
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. Use other parameters at your own risk! With the default parameter set, the plaintext type is vector of u8
with a fixed length 2048.
