This is the homepage for the implementation of anonymous tokens.
Anonymous Tokens are lightweight, single-use anonymous credentials. They were introduced by Davidson et al. (PETS 2018. Here we implement both the initial algorithms as well as the extensions proposed in CRYPTO 2020. Extended benchmarks - generated with criterion.rs - are available.

The code is heavily based on (dalek-cryptography)[https://dalek.rs/], an excellent suite of pure-rust cryptographic libraries
(more specifically, I am using (
