NIST on Electronic Voting

The NIST has released a draft white paper on electronic voting machines. Washington Post summarizes:

Paperless electronic voting machines used throughout the Washington region and much of the country “cannot be made secure,” according to draft recommendations issued this week by a federal agency that advises the U.S. Election Assistance Commission.

NIST says in its report that the lack of a paper trail for each vote “is one of the main reasons behind continued questions about voting system security and diminished public confidence in elections.” The report repeats the contention of the computer security community that “a single programmer could ‘rig’ a major election.”

Fears about rigging have animated critics for years, but there has been no conclusive evidence that such fraud has occurred. Electronic voting systems have had technical problems — including unpredictable screen freezes — leaving voters wondering whether their ballots were properly recorded.

Computer scientists and others have said that the security of electronic voting systems cannot be guaranteed and that election officials should adopt systems that produce a paper record of each vote in case of a recount. The NIST report embraces that critique, introducing the concept of “software independence” in voting systems.

NIST says that voting systems should not rely on a machine’s software to provide a record of the votes cast. Some electronic voting system manufacturers have introduced models that include printers to produce a separate record of each vote — and that can be verified by a voter before leaving the machine — but such paper trails have had their own problems.
