Helios: Open-Source End-to-End Verifiable Voting System
A secure and transparent voting system allowing voters to cast encrypted ballots while verifying inclusivity of final tallies, built with open-source principles.
What is Helios?
Helios is an open-source electronic voting system that focuses on verifiability and transparency of the voting process. It utilizes cryptography and distributed trust to allow voters to verify that their votes were cast and counted as intended, while preserving the secrecy of their ballot. Some key features of Helios:
- Voters receive a tracker that allows them to independently confirm that their ballot reached the servers and was included in the final tally. This provides end-to-end verifiability.
- Votes are encrypted on the client-side using homomorphic encryption before being sent to the Helios servers. This prevents the voting admin or server from seeing individual vote choices.
- Anyone can verify the integrity of the encrypted ballots and tally results by running open-source tallying code. This provides universal verifiability of the full election results.
- Helios supports voting via a simple web interface or integrated as part of an existing app. It focuses on usability while still providing verifiability.
- Helios has been used in binding elections by universities, open-source projects, unions, and governments around the world.
Overall, Helios is ideal for organizations wanting to conduct transparent, trustworthy voting with high integrity.
