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 http://avirubin.com/vote.pdf
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 [ http://www2.diebold.com/checksandbalances.pdf
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. < http://www.dbm.maryland.gov/SBE
and RABA Technologies [Trusted Agent Report -- Diebold AccuVote-TS Voting System, RABA Technologies, Jan. 20, 2004. http://www.raba.com/text/press/TA_Report_AccuVote.pdf
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. http://www.sos.state.oh.us/sos/hava/files/InfoSentry1.pdf
and Compuware [Direct Recording Electronic (DRE) Technical Security Assessment Report, Compuware Corporation, 21
November 2003. http://www.sos.state.oh.us/sos/hava/files/compuware.pdf
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:

and then a Top to Bottom Review was released by the California Secretary of State Bowen in October 2007 [ http://www.sos.ca.gov/elections/elections_vsr.htm
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.
