Abstract

We present a receipt-free voting scheme based on a mixtype anonymous channel[Cha81, PIK93]. The receipt-freeness property [BT94] enables voters to hide how they have voted even from a powerful adversary who is trying to coerce him. The work of [BT94] gave the first solution using a voting booth, which is a hardware assumption not unlike that in current physical elections. In our proposed scheme, we reduce the physical assumptions required to obtain receipt-freeness. Our sole physical assumption is the existence of a private channel through which the center can send the voter a message without fear of eavesdropping.
