Implementation of Rai-Choo!

This repository contains a prototypical implementation of the Rai-Choo! blind signature scheme.

Dependencies

Before compilation, first ensure that the gmp dependency is installed. For that, install libgmp3-dev using

sudo apt-get install libgmp3-dev 

Install the mcl dependency. A simple way to do that is to clone the mcl repository via

git clone https://github.com/alinush/go-mcl.git

and then use

cd go-mcl
./scripts/install-deps.sh

Additionally, you need the openssl library. You can install it using

sudo apt-get install libssl-dev

Parameter Selection (Optional)

If you want to use/test parameters different than the standard parameters (N=8,K=54), then go to file src/parameters.hpp and change the line #define MEDIUM_N_PARS to #define LOW_N_PARS (N=4,K=80) or #define HIGH_N_PARS (N=32,K=33).

Building

Run

cd build
make all

Then, there should be an executable file Raichoo in this directory.
