An Updated List of Scientific Studies (from 2003 to 2007) Revealing
Diebold/Premier Election Solutions Security Flaws


Scientific studies of Diebold/Premier Election Solutions' voting
systems have unanimously revealed security flaws in its touch-screen
and optical scan voting systems.

On July 24, 2003, Tadayoshi Kohno, Adam Stubblefield, Aviel D. Rubin
and Dan S. Wallach released a report on their analysis of the security
of the Diebold AccuVote direct recording electronic voting system
[Tadayoshi Kohno, Adam Stubblefield, Aviel D. Rubin and Dan S.
Wallach, Analysis of an Electronic Voting System, posted to the web
July 24, 2003 as ];

This story was covered on the same day by the New York Times [John
Schwartz, Computer Voting is Open to Easy Fraud, Experts Say, The New
York times July 24, 2003, page A12.]

While the vendor has strenuously denied the significance of these
flaws [ ]

subsequent reports commissioned by the state of Maryland from Science
Applications International Corporation (SAIC) [Risk Assessment Report:
Diebold Accuvote-TS Voting System and Processes, as redacted by the
State of Maryland, Science Applications International Corporation
SAIC-6099-2003-261, Sept 2, 2003. < ]

and RABA Technologies [Trusted Agent Report -- Diebold AccuVote-TS
Voting System, RABA Technologies, Jan. 20, 2004. ]

and a study by the state of Ohio from InfoSentry [DRE Security
Assessment, Volume 1, Computerized Voting Systems, Summary of Findings
and Recommendations, InfoSENTRY, 21 November 2003. ]

and Compuware [Direct Recording Electronic (DRE) Technical Security
Assessment Report, Compuware Corporation, 21 November 2003. ]

all substantially confirm all of the major security flaws identified
in the Hopkins report and identified several additional flaws.
According to Iowa Computer Scientist and Voting System Expert Doug
Jones, "It is noteworthy that none of these studies are complete; each
has missed some of the security flaws identified in the others."

And more recent studies of Diebold/PES voting systems have been released:

In November, 2007 the unredacted versions of SAIC's Maryland Diebold
Report, September 2, 2003 which had been redacted by Maryland's
Election Director and NASED President Linda Lamone, were finally
publicly released. (Complete, unredacted version, 197 pages including
suggested edits and changes as made by unknown party.)

and scientific studies were done in 2006 and 2007 for the State of
Connecticut by the University of Connecticut Engineering Department [ ]

and then a Top to Bottom Review was released by the California
Secretary of State Bowen in October 2007 [ ]


Thank you to all of the investigators, election officials, computer
scientists, and election advocates who made these studies possible and
brought attention to them and thank you to Brad Friedman, Doug Jones
and others for listing some of these URLs on their web sites.

It is not just Diebold's Premier Election Solution voting systems
which has security flaws. Other systems have many security flaws too,
as shown in the CA SOS's Top to Bottom Review results.

These expert studies show that we need to implement routine effective
independent manual audits of election results or the machine counts
can undetectably put candidates into office whom voters do not elect.

Connecticut seems to come closest to conducting effective routine
election audits, but Connecticut could improve its election audit
effectiveness and reduce its administrative burdens for doing audits
by doing them more scientifically. See
