Software to study attacks on the Learning Parity with Noise problem

Attacks on Learning Parity with Noise

This software package allows to construct attacks on LPN. The examples/ directory shows many examples of solving algorithms that solve various LPN instances using various (combinations of) reductions and solution-finding algorithms.


  1. Get Rust and Cargo set up. You may need the nightly version (as of September 2018).
  2. cargo run --release --example bkw
