rsTFHE

The library implements Fast Fully Homomorphic Encryption Library over the Torus in Rust.

version v1.1.0 implements fft and using spqlios

version v1.0.0 very slow homnand

benchmarks

How to Run

cargo run --example homnand --features=spqlios --release

cargo test -- --nocapture nand
cargo test --features=fft -- --nocapture nand
cargo test --features=spqlios -- --nocapture nand
cargo bench
cargo bench --features=fft # (x3)
cargo bench --features=spqlios # (x10)

TODO

  • implements fft
  • implements spqlios
  • compare spqlios fma, avx, unaligned
  • reduce todo, fixme
  • mesure key size
    • bench-rs?
