This simple defect enables vote buying and coercion which are impractical in current physical election systems due to the &#8220;plausible deniability&#8221; offered by a voting booth. This defect is embedded, not only within prior election protocols, but within all of the more general protocols for collective computation of a public function from private inputs. This paper presents the first verifiable secret-ballot election protocols in which participants are unable to prove to others how they voted.<\/p>\n<\/div>\n<p><!-- .asset-content --><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Prior verifiable secret-ballot election protocols all suffer from a common defect which renders them unsuitable for practical use: they allow voters to (if they wish) carry away from the protocol receipts which can be used to prove to others how they voted.
