The e-voting used in the EPFL voting since 2018. It allows users to vote on a distributed system that will wait for the election to be over before decrypting the votes, keeping anonymity of the users.

Our e-voting system is inspired by the first version of Helios where the encrypted ballots are shuffled and anonymized before they are decrypted. Instead of the shuffle used in Helios, we implemented a Neff shuffle which is much faster than the original Helios shuffle.
