As a follow up, Ben has built his voter-verifiable voting system on the web. Look for Helios Voting.

You asshole! You are talking about voting and you have a preference? Where is your integrity!!!
StephenWeis (November 30, 1999 at 12:00 am)
There doesn't have to be one centralized bulletin board. The key property Ben is trying to get at with the bulletin board analogy is that voters can go and check that their encrypted ballot appears in some publicly accessible repository, which may be distributed. If the vote does not appear, then the voter will have a receipt that they can turn over to an investigative agency. Denial of service, like in the example you give, is always a risk, but can be detected and prevented.

:) Quick question: I wonder whether it would be dangerous to rely on one centralised website or 'bulletin board', to avoid coercers taking over a university or ISP proxy server and fooling many voters into thinking their votes are corrupted... How important is the bulletin board itself in the overall auditing scheme?

Excellent video, way better than hearing about Alice and Bob and Eve again... great examples, great ideas, great explanations.
