Abstract: We present an efficient, covert-channel-resistant, receipt-free ballot casting scheme that can be used by humans without trusted hardware. In comparison to the recent Moran-Naor proposal, our scheme produces a significantly shorter ballot, prevents covert channels in the ballot, and opts for statistical soundness rather than everlasting privacy (achieving both seems impossible). The human interface remains the same, based on Neff's MarkPledge scheme, and requires of the voter only short-string operations.
