Security Seals on Voting Machines
Related to this blog post from Wednesday, here’s a paper that looks at security seals on voting machines.
Andrew W. Appel, “Security Seals on Voting Machines: A Case Study,” ACM Transactions on Information and System Security, 14 (2011): 1–29.
Abstract: Tamper-evident seals are used by many states’ election officials on voting machines and ballot boxes, either to protect the computer and software from fraudulent modification or to protect paper ballots from fraudulent substitution or stuffing. Physical tamper-indicating seals can usually be easily defeated, given they way they are typically made and used; and the effectiveness of seals depends on the protocol for their application and inspection. The legitimacy of our elections may therefore depend on whether a particular state’s use of seals is effective to prevent, deter, or detect election fraud. This paper is a case study of the use of seals on voting machines by the State of New Jersey. I conclude that New Jersey;s protocols for the use of tamper-evident seals have been not at all effective. I conclude with a discussion of the more general problem of seals in democratic elections.

Excellent paper! I don’t think I’ve seen so many seal types examined all at once before.
New Jersey appears to be working with laws specifying procedures that assume mechanical voting machines (not that this is unusual in the US). E.g. here: “Such representatives shall certify … that all of the counters are set at zero (000) … Every voting machine shall be furnished with a lantern, or an electric light fixture, which shall give sufficient light to enable voters while voting to read the ballots and be suitable for use by the district board in examining the counters.”
