“…Furthermore, a number of protocols were made to conduct cryptographic proxy voting [37], [38]. The first protocol [37] introduces delegation to different proxies with different priorities by using hash chain elements as credentials.…”

“…This approach, however, does not offer verifiability for external observers and does not allow for vote updating or voter credentials reuse. In the second protocol [38], the voters either encrypts and casts the vote published by their chosen proxy at the beginning of the election, or cast the encrypted name of their chosen proxy as their vote. Hence, vote secrecy for the votes cast by proxies is not ensured.…”

“…As Internet voting has been gaining attention in both research and practical applications in real-world elections [1], a number of Internet voting schemes have also been designed to support the latter case for proxy voting [2,3,4,5]. In particular, one of these schemes [5] extends the well-established Internet voting scheme, Helios [6], towards proxy voting functionality.…”

Proxy voting is a form of voting meant to support the voters who want to delegate their voting right to a trusted entity, the so-called proxy. Depending on the form of proxy voting, the proxy is either authorized to cast a ballot for the voting option that the voter chooses, or to vote according to her own wishes, if the voter is not sure how to vote and wants to delegate the decision making in the election. While the first form of proxy voting has been applied to traditional elections in order to support the voters who are unable to physically get to a polling station, the second form has been a topic of research in Internet voting. Recently, an Internet voting scheme has been proposed, that extends the well-known Helios scheme towards the functionality of proxy voting. This scheme, however, also has the drawbacks of Helios regarding participation privacy and receipt-freeness. As such, the information whether any voter participated in the election either by casting a direct vote or delegating their vote can be deduced from the published information. The scheme furthermore allows both the voters and the proxies to create receipts that prove casting a ballot for a specific candidate, as well as allows the voters to create receipts that prove delegating to a specific proxy. In this work we use the idea of dummy ballots, proposed in another extension of Helios to extend the proxy voting scheme towards participation privacy and receipt-freeness.
