Receipt-Free Homomorphic Elections and Write-in Ballots
Abstract: We present a voting protocol that protects voters' privacy and achieves universal verifiability, receipt-freeness, and uncoercibility without ad hoc physical assumptions or procedural constraints (such as untappable channels, voting booths, smart cards, third-party randomizers, and so on). We discuss under which conditions the scheme allows voters to cast write-in ballots, and we show how it can be practically implemented through voter-verified (paper) ballots. The scheme allows voters to combine voting credentials with their chosen votes applying the homomorphic properties of certain probabilistic cryptosystems.
