DC Suspends Tests of Online Voting System

Fortran IV writes "Back in June, Washington, DC signed up with the The Open Source Digital Foundation to set up an internet voting system for DC residents overseas. The plan was to have the system operational by the November general election. Last week the DC Board of Elections and Ethics opened the system for testing and attracted the attention of students at the University of Michigan, with comical results. The DC Board has postponed implementation of the system for 'more robust testing.'" Update: 10/06 02:42 GMT by T : University of Michigan computer scientist J. Alex Halderman provides an explanation of exactly how the folks at Michigan exploited the DC system.

Inline PDF forms!?!

[dgatwood]

One of the articles mentioned that some browsers submitted blank forms because they don't support inline PDF forms. Who, exactly, thought that using PDF was a good idea? The whole point of the web is that it provides layout standards. Why even bother using a web browser if you're just going to try to hack around it by using a completely different content format, PDF, shoved in using browser plug-ins. It might has well have been Flash. Use the web or do not. There is no halfway.

And of course, their servers were obviously insecure, as evidenced by someone managing to alter content on the servers.

What does all this tell us? Well, it tells us that:

• For anything approaching secure content delivery, the actual content (the HTML pages, the javascript files, etc.) must be signed prior to installation on the servers, not signed by the servers that provide it.
• Web-based clients lack the infrastructure to verify signatures on the content itself except for the signatures provided by the servers.
• Web-based clients are therefore inherently insecure.

Not that this shouldn't have been anything less than obvious to anyone with even a basic understanding of computer security.... Real secure networks built on top of HTTP use client applications that verify signatures on the content that the servers provide, ensuring that it is legitimate before acting on it. This also, of course, requires that people obtain the client software in a secure fashion, which is a problem in and of itself, in much the same way that obtaining the client on-the-fly from a web server is a problem, and for precisely the same reason.

Web-based clients are therefore inherently insecure.

Web-based clients are insecure simply because you don't have physical control over them. You don't control the network, the routers, or the client machine. Give me (or some malware author) the client machine, and who cares what you signed on the server or how?

Imagine this: You're a security consultant. A client says: Secure this system, it can change the course of U.S. history (so it has a little value). And by the way, the system extends to 150 million clients running every kind of hardware, software, and configuration imaginable, maybe 25% of which are infected with malware, and to which we have no access and over which we have no control. Oh yeah, and any computer on earth could be a vector of attack and everything from foreign intelligence agencies to corrupt politicians to radical political groups to greedy businesses might have a motive.

Why are we even discussing this as a possibility?

if we can't make online voting work, we can't function at all in the digital age.

Current history disproves this your statement. We cannot yet make online voting work and yet we function pretty well in the "digital age".

There were no reports of fraud whatsoever

Indeed.

Re:Electronic voting, yes! Online voting, no!

Voting machines should definitely be electronic.

Why? What exactly do electronic voting machines give you that, say, an optical scan paper ballot doesn't? Electronic voting has more often than not been a solution in search of a problem.

I can do everything else online.

[Anonymous Coward]

I can check my bank accounts online.
I can pay my bills online.
I can order almost anything imaginable online.
I can participate in auctions online.
I can date online.
I can gamble online.
I can see my credit reports online.
I can file my taxes online.

Why is voting so different?

Because these other endevours do not require anonymity.

Voter coersion is a real problem.
