We propose a new voting scheme, BeleniosRF, that offers both receipt-freeness and end-to-end verifiability. It is receipt-free in a strong sense, meaning that even dishonest voters cannot prove how they voted. We provide a game-based definition of receipt-freeness for voting protocols with non-interactive ballot casting, that we name strong receipt-freeness (sRF). To our knowledge, sRF is the first game-based definition of receipt-freeness in the literature, and it has the merit of being particularly concise and simple.

Built upon the Helios protocol, BeleniosRF inherits from its simplicity, and does not require revoting nor an untappable channel. We implement BeleniosRF, and show its feasibility in a number of platforms, including desktop computers and smartphones.
