Open-Audit Elections

Ben Adida

While the debate over voting-machine paper trails rages on in the press, an end-to-end verifiable solution exists: open-audit elections. In an open-audit election, Alice, the voter, receives direct assurance that her vote was correctly captured *and tallied*. Any political party or activist organization can corroborate this verification. Surprisingly, ballot secrecy is preserved.

In this talk, we review the cryptographic techniques that make open-audit elections possible. We also present some new developments in both vote casting and tallying that should improve practicality and simplify the explanation of open-audit voting techniques.
