Reverie

An efficient implementation of the NIZKPoK outlined in KKW 2018

CI

Reverie is an implementation (prover and verifier) of the MPC-in-the-head NIZKPoK outlined in Improved Non-Interactive Zero Knowledge with Applications to Post-Quantum Signatures. Reverie seeks to offer concrete prover efficiency (linear proving time with small constants) for complex predicates. The implementation seeks to offer 128-bits of (classical) security and support arbitrary rings, most efficiently Z2 and Z64.

Reverie provides both a library (with a simplified and a streaming interface), in addition to a CLI program for proving/verifying statements specified in Bristol format to enable easy experimentation.

Running

Reverie requires a relatively recent nightly Rust.

Using SSE+AESNI

console time RUSTFLAGS="-C target-cpu=native -C target-feature=+aes,+ssse3,+sse2" cargo run --release

Or even better with AVX2+AESNI

console time RUSTFLAGS="-C target-cpu=native -C target-feature=+aes,+ssse3,+sse2,+avx2" cargo run --release
