An Efficient Homomorphic Coercion Resistant and E2E Verifiable Voting Scheme

Coercion-Resistant Electronic Elections with Write-In Candidates

It is often argued in the e-voting community that in the presence of write-in candidates, forced abstention attacks are always possible. Therefore, write-in candidates are often excluded in existing definitions of coercion-resistance arguing that those definitions cannot be achieved by write-in supporting schemes. This is only true if the tally is made public directly. Coercionresistance may we...

Prêt à Voter: All-In-One

A number of voter-verifiable electronic voting schemes have been introduced in the recent decades. These schemes not only provide each voter with a receipt without the threat of coercion and ballot selling, but also the ballot tallying phase can be publicly verified. Furthermore, these schemes are robust because the power of authorities can be threshold distributed. Generally speaking, the homo...

Achieving Meaningful Efficiency in Coercion-Resistant, Verifiable Internet Voting

In traditional voting schemes with paper, pens, and ballot-boxes, appropriate procedures are put in place to reassure voters that the result of the tally is correct. Considering that in Internet voting errors or fraud will generally scale over a much greater fraction of votes, the demand to get strong reassurances as well, seems more than justified. With the ambition of offering a maximum degre...

Theoretical Attacks on E2E Voting Systems

We give a survey of existing attacks against end-to-end verifiable voting systems in the academic literature. We discuss attacks on the integrity of the election, attacks on the privacy of voters, and attacks aiming at coercion of voters. For each attack, we give a brief overview of the voting system and a short description of the attack and its consequences.
