trailofbits/reverieEfficient implementation of the KKW zero-knowledge proof system for arbitrary rings, providing prover and verifier with linear proving time and 128-bit security.
An efficient implementation of the NIZKPoK outlined in KKW 2018
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.
Reverie requires a relatively recent nightly Rust.
Using SSE+AESNI
time RUSTFLAGS="-C target-cpu=native -C target-feature=+aes,+ssse3,+sse2" cargo run --release
Or even better with AVX2+AESNI
time RUSTFLAGS="-C target-cpu=native -C target-feature=+aes,+ssse3,+sse2,+avx2" cargo run --release
