Receipt-Freeness in Large-Scale Elections without Untappable Channels

: For an electronic election to be fully democratic there is a need for security mechanisms that will assure the privacy of the voters. With receipt-free electronic voting, a voter neither obtains nor is able to construct a receipt proving the content of her vote. In this paper we first consider the minimal requirements for receipt-free elections, without untappable communication channels between the voter and the voting authorities. We then propose a solution, which satisfies these requirements. This solution is based on an encryption blackbox, which uses its own randomness. Finally we present an implementation with smartcards, suitable for Internet voting.
