PSI - Rust

Private Set Intersection protocol based on ECDH, Bloom Filters, and Golomb Compressed Sets.

This crate provides Rust bindings to the core C++ PSI library, by wrapping the C interface.

Requirements

For developing with rust, you need Cargo which is used to update dependencies.

  • Cargo
  • Raze install with cargo install cargo-raze

Build and test

Build libraries and documentation with or without optimizations:

# Build everything using the fastbuild optimization configuration

bazel build //private_set_intersection/rust/...

# With a specific optimization flag '-c opt'
bazel build -c opt //private_set_intersection/rust/...

Build and run tests:

bazel test -c opt //private_set_intersection/rust/...

Run the benchmark:

bazel run -c opt //private_set_intersection/rust:bench

Use in other projects

Add deps = ["@org_openmined_psi//private_set_intersection/rust:psi"] to your Bazel rule in your project's BUILD file.

Developing

Typically, Rust projects are built using Cargo, which reads the Cargo.toml file to pull necessary dependencies. In this project, Bazel is used, so a dummy Cargo.toml is created in //third_party/cargo to specify the necessary dependencies. The dummy Cargo.toml should be edited to add or update dependencies.

Afterwards, run cargo raze in the //third_party/cargo directory to generate the build files for the Rust dependencies. Cargo raze can be installed through cargo install cargo-raze. This should only need to be done once after updating the dummy Cargo.toml.
