Why seals can't secure elections
Over the last few weeks, I’ve described the chaotic attempts of the State of New Jersey to come up with tamper-indicating seals and a seal use protocol to secure its voting machines. A seal use protocol can allow the seal user to gain some assurance that the sealed material has not been tampered with. But…

Do photo IDs help prevent vote fraud?
In many states, an ID is required to vote. The ostensible purpose is to prevent people from casting a ballot for someone else – dead or alive. Historically, it was also used to prevent poor and minority voters, who are less likely to have government IDs, from voting. No one would (publicly) admit to the…

Internet Voting in Union Elections?
The U.S. Department of Labor (DOL) recently asked for public comment on a fascinating issue: what kind of guidelines should they give unions that want to use “electronic voting” to elect their officers? (Curiously, they defined electronic voting broadly to include computerized (DRE) voting systems, vote-by-phone systems and internet voting systems.) As a technology policy…

Seals on NJ voting machines, March 2009
During the NJ voting-machines trial, both Roger Johnston and I showed different ways of removing all the seals from voting machines and putting them back without evidence of tampering. The significance of this is that one can then install fraudulent vote-stealing software in the computer. The State responded by switching seals yet again, right in…

What an expert on seals has to say
During the New Jersey voting machines lawsuit, the State defendants tried first one set of security seals and then another in their vain attempts to show that the ROM chips containing vote-counting software could be protected against fraudulent replacement. After one or two rounds of this, Plaintiffs engaged Dr. Roger Johnston, an expert on physical…

The trick to defeating tamper-indicating seals
In this post I’ll tell you the trick to defeating physical tamper-evident seals. When I signed on as an expert witness in the New Jersey voting-machines lawsuit, voting machines in New Jersey used hardly any security seals. The primary issues were in my main areas of expertise: computer science and computer security. Even so, when…

Seals on NJ voting machines, October-December 2008
In my examination of New Jersey’s voting machines, I found that there were no tamper-indicating seals that prevented fiddling with the vote-counting software—just a plastic strap seal on the vote cartridge. And I was rather skeptical whether slapping seals on the machine would really secure the ROMs containing the software. I remembered Avi Rubin’s observations…

Seals on NJ voting machines, 2004-2008
I have just released a new paper entitled “Security seals on voting machines: a case study” and here I’ll explain how I came to write it. Like many computer scientists, I became interested in the technology of vote-counting after the technological failure of hanging chads and butterfly ballots in 2000. In 2004 I visited my…

Unpeeling the mystique of tamper-indicating seals
As computer scientists have studied the trustworthiness of different voting technologies over the past decade, we notice that “security seals” are often used by election officials. It’s natural to wonder whether they really provide any real security, or whether they are just for show. When Professor Avi Rubin volunteered as an election judge (Marylandese for…

Paper vs. Electronic Voting in Today's Election in Houston
(Cross-posted at the Computing@Rice blog at the Houston Chronicle.) Back in late August, Harris County (Houston)’s warehouse with all 10,000 of our voting machines, burned to the ground. As I blogged at the time, our county decided to spend roughly $14 million of its $40 million insurance settlement on purchasing replacement electronic voting machines of…
