Helios Voting is the first and the only publicly available online voting system with end-to-end cryptographic verifiability. It's been operational since 2008. 1M eligible voters have cast 500,000 votes in more than 10,000 elections run by university faculty, students, non-profits, private clubs, and professional organizations, including the IACR, Princeton, Doctors without Borders, the ACM, UCL in Belgium, the Technion in Israel, and many others. You'd be surprised by how many tenure cases are decided on Helios! With ever increasing calls for online voting for political office, we may be able to draw some interesting lessons from 10 years of operating Helios. This talk explores three lessons: (1) the importance of building security systems commensurate with their threat model, (2) the importance of logs and forensics, (3) the broad human need for some trusted third parties. We conclude with some thoughts on whether secure online voting for political office is within sight, and consider the possibility of truly auditable in-person elections.
