Receipt-Free Universally-Verifiable Voting with Everlasting Privacy
We present the first universally verifiable voting scheme that can be based on a general assumption (existence of a non-interactive commitment scheme). Our scheme is also the first receipt-free scheme to give "everlasting privacy" for votes: even a computationally unbounded party does not gain any information about individual votes (other than what can be inferred from the final tally). Our voting protocols are designed to be used in a "traditional" setting, in which voters cast their ballots in a private polling booth (which we model as an untappable channel between the voter and the tallying authority).

We give a generic voting protocol which we prove to be secure in the Universal Composability model, given that the underlying commit...
