“…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. The scheme in [5] preserves the security properties and user experience of Helios.…”

“…As such, it does not ensure participation privacy, as the identities of the voters who participated in the election, as well as of the voters who delegated their vote 1 are published. Furthermore, the voters in [5], as well as in Helios, are capable of creating receipts that prove to a third party how they voted. This enables vote selling due to the lack of receipt-freeness.…”

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.

“…In 2016, Kulyk et al [24] proposed a new coercion-resistant proxy voting scheme by extending the coercion-resistant JCJ/Civitas theme, aiming to prevent direct voter coercion, delegation coercion, and proxy coercion. They also proposed a new proxy voting scheme [25] to extend the Helios voting system [26] with delegated voting functionality. In 2017, Cohensius et al [27] considered a social choice problem and demonstrated that the mechanism using proxy voting better approximates the optimal outcome.…”

Design and Implementation of a Mobile Voting System Using a Novel Oblivious and Proxy Signature

Electronic voting systems can make the voting process much more convenient. However, in such systems, if a server signs blank votes before users vote, it may cause undue multivoting. Furthermore, if users vote before the signing of the server, voting information will be leaked to the server and may be compromised. Blind signatures could be used to prevent leaking voting information from the server; however, malicious users could produce noncandidate signatures for illegal usage at that time or in the future. To overcome these problems, this paper proposes a novel oblivious signature scheme with a proxy signature function to satisfy security requirements such as information protection, personal privacy, and message verification and to ensure that no one can cheat other users (including the server). We propose an electronic voting system based on the proposed oblivious and proxy signature scheme and implement this scheme in a smartphone application to allow users to vote securely and conveniently. Security analyses and performance comparisons are provided to show the capability and efficiency of the proposed scheme.

This paper aims to provide a guideline for identifying the most suitable online voting system under the given requirements and acceptable tradeoffs. We have selected twelve (more or less) well‐known online voting systems that rely on distinct cryptographic mechanisms for achieving security. For each of the systems, we summarized the key architectural and cryptographic ideas behind their design. Then, we analyzed the required trust assumptions for achieving the three most important security properties (i.e., verifiability, divided between cast‐as‐intended, recorded‐as‐cast, and tallied‐as‐recorded verifiabilities, privacy, and receipt‐freeness). To make a fair comparison, we did our analysis based on identical security definitions. Note that we selected wildly known and well‐accepted definitions, which are scheme‐neutral, to avoid any biases. Also, we discussed some of the most critical practical aspects of those systems, such as–the necessity for secure or anonymous channels, reliance on secure printer facilities and so forth. To facilitate the comparison, we suggested a unified naming convention for system elements based on their roles and functions. Then, based on the unified naming convention, we compared all twelve online voting systems for both the security properties and practical aspects. Finally, we summarized our observations regarding patterns and dependencies we observed, provided guidelines for selecting the online voting system, and gave recommendations regarding system design. We hope our work contributes to the online literature and facilitates the process of selecting the most suitable e‐voting system depending on the requirements of a specific election.
