Implmentation of lattice-based encryption method ring-LWE in pure Rust.
Description: This provides the basic PKE (keygen, encryption, and decryption) operations for the ring learning-with-errors and module learning-with-errors scheme.
Disclaimer: This is not secure. It is not written in constant-time nor resistant to other side-channel attacks. This is intended for educational use and not for real-world applications.
Usage: In the src directory,
cargo build
To build the binary.
cargo test
- Performs keygen/encrypt/decrypt for a test message.
- Checks homomorphic addition and multiplcation hold for small values.
Note: Parameters optional via
--params <n> <q> <t>for ring-LWE
where n is the polynomial degree, q is the ciphertext modulus, t is the plaintext modulus.
If ommitted, the default parameters will be used.
cargo run -- keygen
This will generate a public/secret keypair.
cargo run -- encrypt <public_key> <message>
Generates the ciphertext.
cargo run -- decrypt <secret_key> <ciphertext>
Decrypts the ciphertext given a secret key, printing the plaintext message.
