We can't let people prove who they voted for, even if we open their ballot for the audit. So we use crypto! So we use homomorphic encryption to blind stuff and hide it [ this looks like partially homomorphic encryption is all that's required also I am totally not typing math ]

So everyone can reproduce the results [ there's math and zero-knowledge proofs and the speaker is not going to go there in this talk ] ... ok, so now how the heck do people who aren't cryptographers trust this result???

Get people to vouch for the math? Would this work? Send opinions to the speaker. Why don't we have these technologies today? Risk limiting audits are going well -- pilots are close to happening and you can tack them on to the end of an election so it's easier to deploy

But we're not seeing this development in end-to-end verifiable elections or secure voting machines? Why? Because the funding came after the 2000 election kerfuffle. And there isn't enough.

Certification: we certify elections to show trust. But it's expensive and slow to get the certification so it's making elections less secure which *erodes* trust.

What can we do? Security people doing all the security work is really important. Check out election guard -- write verifiers. Reach out if you have an idea to improve certification.

Q
@flamsmark: why is the goal to convince voters in particular? [ YES! Why only voters? ] A: Well, I'm a voter and want to be convinced. Do you have a suggestion for a better target? [ continued]1 reply 1 proslijeđeni tweet 0 korisnika označava da im se sviđaPrikaži ovu nit -
[ continued ] Q: People who can't vote but live in the affected area. People who live outside of the area entirely but who are very affected by an election. A: great insight.

Q: I've heard from election officials that they're worried about the level of transparency that you advocate. Have you encountered this type of resistance? A: We've all run into security through obscurity. But the best security comes through open source.

Q
@n2vi : are there other aspects of the voting system where you think tech could help? A: Voter registration databases. This is part of why doing security work in general is so important and this is stuff we know how to do.1 reply 0 proslijeđenih tweetova 0 korisnika označava da im se sviđaPrikaži ovu nit
Q nlidz: did you consider using a safer language rather than reproducing the mistakes of the past? A: I spend a lot of time ensuring that C is memory-safe. But the reality is that we need to use things that people can use, and C felt like a way to maximize that.
