From Electronic to Cryptographic Voting

Electronic voting machines were supposed to make elections cheaper, faster, and more secure, but so far they have failed. In the last decade there has been something of a rush to adopt¬† e-voting, followed by suspicion and controversy over the black-box, “just trust us” nature of the first generation of commercial systems, followed by a return to paper ballots in many jurisdictions. However, if we wish to improve election processes, cheap and fast is probably the wrong goal. It may be possible to use cryptographic techniques to implement end-to-end auditable elections, new in human history.

The e-voting fiasco has illustrated that paper ballots are a better system than they might at first seem. Paper preserves voter secrecy, it is auditable after the fact, and it is even reasonably transparent, if one also allows election observers. But paper ballots must be closely guarded and cannot be directly counted by members of the general public, who in the end have no choice but to trust election officials,  observers, counting equipment, and the entire chain of custody. Rather than simply duplicating paper ballots electronically, we should strive to improve upon them.

This seems to be possible. Modern cryptography suggests the possibility of a new kind of incredibly transparent and fair election, where ordinary citizens can verify the soundness of the election for themselves, without ever needing to trust blindly that a huge array of machines and people have acted correctly. This represents a fundamentally new ability: for the first time, it may be possible to hold truly “open” elections.
