Hacking Diebold voting machines, redux

'Hotel minibar' keys open Diebold voting machines

Ed Felten, Freedom to Tinker:

A little research revealed that the exact same key is used widely in office furniture, electronic equipment, jukeboxes, and hotel minibars. It’s a standard part, and like most standard parts it’s easily purchased on the Internet. We bought several keys from an office furniture key shop — they open the voting machine too. We ordered another key on eBay from a jukebox supply shop. The keys can be purchased from many online merchants.

Using such a standard key doesn’t provide much security, but it does allow Diebold to assert that their design uses a lock and key. Experts will recognize the same problem in Diebold’s use of encryption — they can say they use encryption, but they use it in a way that neutralizes its security benefits.

Felton led the Princeton team whose investigation of Diebold voting machines I've previously posted here.
