  1. Electronic voting for Australia Vanessa Teague Department of Computer Science and Software Engineering University of Melbourne Australia

  2. Key questions/issues (for me) • To find electronic voting solutions that are appropriate for Australian elections, which means • Single transferable vote (STV) (a.k.a. preferential voting or instant-runoff voting) • Voters list all candidates in order of preference • Many e-voting schemes don’t work for STV • Receipt freeness is harder for STV • Compulsory voting • Makes for different tradeoffs

  3. My work: Coercion resistance • Addressing the “Italian attack” for STV • The coercer orders a voter to select a particular permutation • During tallying (or after the election), the coercer looks for that vote

  4. Key results • A definition of coercion-resistance that includes STV • A scheme for proving correct STV tallying without allowing coercion • Based on (honest-verifier) Zero knowledge proofs
