Abstract

Coercion-resistance is one of the key requirements of voting systems as it prevents an outsider from trying to persuade the voter to vote in a certain way. Although it usually implies receipt-freeness [15], it is usually formalised as a stronger property [23]. In this paper we analyse two voting schemes for coercion-resistance, namely Prêt à Voter [12] and FOO [17], and find that many of the requirements can be expressed in terms of a fairly recent security property, opacity [5]. We then present a new formalisation of coercion-resistance by casting it as opacity.
