Selections: Internet Voting with Over-the-Shoulder Coercion-Resistance
The authors present Selections, a new cryptographic voting protocol that is end-to-end verifiable and suitable for Internet voting. After a one-time in-person registration, voters can cast ballots in an arbitrary number of elections. They say a system provides over-the-shoulder coercion-resistance if a voter can undetectably avoid complying with an adversary that is present during the vote casting process. The system is the first in the literature to offer this property without the voter having to anticipate coercion and precompute values. Instead, a voter can employ a panic password. They prove that Selections is coercion-resistant against a non-adaptive adversary.
