Student Projects • • Internet voting review Verifiability without paper Voter privacy assessment Code hiding – Can code be hidden undetectably? • Alternative voting systems – ATM, lottery • Secure software distribution – Assure that software inside voting machines is genuine • Voting security standards – What should they look like?
Qualification/Certification • The Federal Election Commission (FEC) published voluntary standards for voting systems • Many states have made the standards mandatory • How to test against them? • The National Association of State Election Directors (NASED) has authorized a small number of Independent testing authorities to qualify voting systems • After qualification, most states have a certification process to verify that the system satisfies state law
Qualification/Certification Problems • The FEC standards are inadequate for software security • The ITAs operate in secret – Don’t publish their testing protocols – Don’t publish their findings, just whether a system passed • The ITAs are paid by the vendors • State certifications are cursory, usually not performed by experts
Help America Vote Act of 2002 • Payments to states to replace paper and level machines: $3 billion • Establishes Election Assistance Commission • Reforms the standards process (National Institute of Standards and Technology) • Provisional voting • Statewide registration systems • Complaint procedure
Punch Card Voting • Will be used by about 14% of the U. S. in 2004 • Will be used in 69 of 88 counties in Ohio (PA only has 67 counties) • Began in the 1960 s with the IBM Porta-Punch • By 2000 was used in 37% of the U. S. , until Florida

Recount • When a ballot is handled, it can be changed • The voter’s intent must be determined • Suppose only one of four corners is detached. It is a vote? • Dimpled chad, pregnant chad: how to count? 17 -803/17 -400 ELECTRONIC VOTING FALL 2004 COPYRIGHT © 2004 MICHAEL I. SHAMOS
What Constitutes a Vote? • “Each State shall adopt uniform and nondiscriminatory standards that define what constitutes a vote and what will be counted as a vote for each category of voting system used in the State. ” HAVA, 42 U. S. C. § 15481(a)(6) • TABLE • PENNSYLVANIA
Punched-Card Problems • • Can’t see whom you’re voting for Registration of card in ballot frame Must use stylus: no positive feedback on punch Hanging chad: chad that is partially attached to the card – How may corners? – Hanging chad causes count to differ every time • Dimple: chad that is completely attached but shows evidence of an attempt to punch – Dimple can turn into a vote on multiple readings 17 -803/17 -400 ELECTRONIC VOTING FALL 2004 COPYRIGHT © 2004 MICHAEL I.

Q&A 17 -803/17 -400 ELECTRONIC VOTING FALL 2004 COPYRIGHT © 2004 MICHAEL I. SHAMOS
What’s a Recount? • Purpose: “verify” that the original tabulation was correct • Three kinds of recounts: – A. Physical ballots exist: Count them again. – B. Computer records exist: Tabulate them again. – C. No physical ballots or computer records exist (e. g. lever machines): Read the counters again 17 -803/17 -400 ELECTRONIC VOTING FALL 2004 COPYRIGHT © 2004 MICHAEL I. SHAMOS
