No More Excuses: Automated Synthesis of Practical and Verifiable Vote-Counting Programs for Complex Voting Schemes
Published in International Joint Conference on Electronic Voting - 2017, 2017
Abstract
We argue that electronic vote-counting software can engender broad-based public trust in elections to public office only if they are formally verified against their legal definition and only if they can produce an easily verifiable certificate for the correctness of the count. We then show that both are achievable for the Schulze method of vote-counting, even when the election involves millions of ballots. We argue that our methodology is applicable to any vote-counting scheme that is rigorously specified. Consequently, the current practice of using unverified and unverifiable vote counting software for elections to public office is untenable. In particular, proprietary closed source vote-counting software is simply inexcusable.
