What proof do we prefer? Variants of verifiability in voting
In this paper, we discuss one particular feature of Internet
voting, verifiability, against the background of scientific
literature and experiments in the Netherlands. In order
to conceptually clarify what verifiability is about, we distinguish
classical verifiability from constructive veriability in
both individual and universal verification. In classical individual
verifiability, a proof that a vote has been counted can
be given without revealing the vote. In constructive individual
verifiability, a proof is only accepted if the witness (i.e.
the vote) can be reconstructed. Analogous concepts are de-
fined for universal veriability of the tally. The RIES system
used in the Netherlands establishes constructive individual
verifiability and constructive universal verifiability,
whereas many advanced cryptographic systems described
in the scientific literature establish classical individual
verifiability and classical universal verifiability.
If systems with a particular kind of verifiability continue
to be used successfully in practice, this may influence the
way in which people are involved in elections, and their image
of democracy. Thus, the choice for a particular kind
of verifiability in an experiment may have political consequences.
We recommend making a well-informed democratic
choice for the way in which both individual and universal
verifiability should be realised in Internet voting, in
order to avoid these unconscious political side-effects of the
technology used. The safest choice in this respect, which
maintains most properties of current elections, is classical
individual verifiability combined with constructive universal
verifiability. We would like to encourage discussion
about the feasibility of this direction in scientific research
Secure and Verifiable Electronic Voting in Practice: the use of vVote in the Victorian State Election
The November 2014 Australian State of Victoria election was the first
statutory political election worldwide at State level which deployed an
end-to-end verifiable electronic voting system in polling places. This was the
first time blind voters have been able to cast a fully secret ballot in a
verifiable way, and the first time a verifiable voting system has been used to
collect remote votes in a political election. The code is open source, and the
output from the election is verifiable. The system took 1121 votes from these
particular groups, an increase on 2010 and with fewer polling places
Public Evidence from Secret Ballots
Elections seem simple---aren't they just counting? But they have a unique,
challenging combination of security and privacy requirements. The stakes are
high; the context is adversarial; the electorate needs to be convinced that the
results are correct; and the secrecy of the ballot must be ensured. And they
have practical constraints: time is of the essence, and voting systems need to
be affordable and maintainable, and usable by voters, election officials, and
pollworkers. It is thus not surprising that voting is a rich research area
spanning theory, applied cryptography, practical systems analysis, usable
security, and statistics. Election integrity involves two key concepts:
convincing evidence that outcomes are correct and privacy, which amounts to
convincing assurance that there is no evidence about how any given person
voted. These are obviously in tension. We examine how current systems walk this
tightrope.Comment: To appear in E-Vote-Id '1
Blockchain, consensus, and cryptography in electronic voting
Motivated by the recent trends to conduct electronic elections using blockchain technologies, we review the vast literature on cryptographic voting and assess the status of the field. We analyze the security requirements for voting systems and describe the major ideas behind the most influential cryptographic protocols for electronic voting. We focus on the great importance of consensus in the elimination of trusted third parties. Finally, we examine whether recent blockchain innovations can satisfy the strict requirements set for the security of electronic voting
Analysis Of Electronic Voting Schemes In The Real World
Voting is at the heart of a country’s democracy. Assurance in the integrity of the electoral process is pivotal for voters to have any trust in the system. Often, electronic voting schemes proposed in the literature, or even implemented in real world elections do not always consider all issues that may exist in the environment in which they might be deployed. In this paper, we identify some real - world issues and threats to electronic voting schemes. We then use the threats we have identified to present an analysis of schemes recently used in Australia and Estonia and present recommendations to mitigate threats to such schemes when deployed in an untrustworthy environment
A framework for comparing the security of voting schemes
We present a new framework to evaluate the security of voting schemes. We utilize the framework to compare a wide range of voting schemes, including practical schemes in realworld use and academic schemes with interesting theoretical properties. In the end we present our results in a neat comparison table.
We strive to be unambiguous: we specify our threat model, assumptions and scope, we give definitions to the terms that we use, we explain every conclusion that we draw, and we make an effort to describe complex ideas in as simple terms as possible.
We attempt to consolidate all important security properties from literature into a coherent framework. These properties are intended to curtail vote-buying and coercion, promote verifiability and dispute resolution, and prevent denial-of-service attacks. Our framework may be considered novel in that trust assumptions are an output of the framework, not an input. This means that our framework answers questions such as ”how many authorities have to collude in order to violate ballot secrecy in the Finnish paper voting scheme?
