writes "Princeton computer science professor Andrew Appel bought 5 $5000 Sequoia electronic voting machines from a government auction site for $82 last month. He and his students may be performing the first security analysis by people who hadn't signed non-disclosure agreements with Sequoia Voting Systems. Appel says that thus far, the Sequoia voting machines appear to be more secure than the Diebold voting machines examined by another Princeton professor last year.
From the Article
Appel says the ROM chips inside are in sockets — not soldered to the board — and can be replaced in ten minutes by opening a door on the back of the machines and unscrewing a metal cover. With new chips, the machines could be reprogrammed to misreport votes, he says....Appel says he opened the machines with a key that came with them, and was able to easily access the machines' motherboards and memory chips to swap them out. But even without the key, a student of his was able to pick the lock in seven seconds."
