Abstract—The secure remote Internet voting protocol play an important role in Internet voting system. The direction of development of remote Internet voting protocol is that implementation of receipt-freeness and coercion-resistance is from with strong physical assumptions to with weak physical assumptions. The final purpose is that receiptfreeness and coercion-resistance is implemented without physical assumptions. In this paper firstly, a receipt-free coercion-resistant remote Internet voting protocol based on MW deniable encryption scheme and BCP commitment scheme is developed. To our best knowledge the proposed remote Internet voting protocol, which has receipt-freeness and coercion-resistance, is the first remote Internet voting protocol implemented without physical assumptions. Secondly, we analyze receipt-freeness and coercionresistance of the proposed remote Internet voting protocol. Finally, we compare security properties of several typical protocols with our present protocol.

Index Terms—physical assumptions, remote Internet voting, deniable encryption, trapdoor commitment scheme, protocol security.
