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
Adaptively Weighted Audits of Instant-Runoff Voting Elections: AWAIRE
An election audit is risk-limiting if the audit limits (to a pre-specified
threshold) the chance that an erroneous electoral outcome will be certified.
Extant methods for auditing instant-runoff voting (IRV) elections are either
not risk-limiting or require cast vote records (CVRs), the voting system's
electronic record of the votes on each ballot. CVRs are not always available,
for instance, in jurisdictions that tabulate IRV contests manually.
We develop an RLA method (AWAIRE) that uses adaptively weighted averages of
test supermartingales to efficiently audit IRV elections when CVRs are not
available. The adaptive weighting 'learns' an efficient set of hypotheses to
test to confirm the election outcome. When accurate CVRs are available, AWAIRE
can use them to increase the efficiency to match the performance of existing
methods that require CVRs.
We provide an open-source prototype implementation that can handle elections
with up to six candidates. Simulations using data from real elections show that
AWAIRE is likely to be efficient in practice. We discuss how to extend the
computational approach to handle elections with more candidates.
Adaptively weighted averages of test supermartingales are a general tool,
useful beyond election audits to test collections of hypotheses sequentially
while rigorously controlling the familywise error rate.Comment: 16 pages, 3 figures, accepted for E-Vote-ID 202
Election Security Is Harder Than You Think
Recent years have seen the rise of nation-state interference in elections
across the globe, making the ever-present need for more secure elections all
the more dire. While certain common-sense approaches have been a typical
response in the past, e.g. ``don't connect voting machines to the Internet''
and ``use a voting system with a paper trail'', known-good solutions to
improving election security have languished in relative obscurity for decades.
These techniques are only now finally being implemented at scale, and that
implementation has brought the intricacies of sophisticated approaches to
election security into full relief.
This dissertation argues that while approaches to improve election security
like paper ballots and post-election audits seem straightforward, in reality
there are significant practical barriers to sufficient implementation.
Overcoming these barriers is a necessary condition for an election to be
secure, and while doing so is possible, it requires significant refinement of
existing techniques. In order to better understand how election security
technology can be improved, I first develop what it means for an election to be
secure. I then delve into experimental results regarding voter-verified paper,
discussing the challenges presented by paper ballots as well as some strategies
to improve the security they can deliver. I examine the post-election audit
ecosystem and propose a manifest improvement to audit workload analysis
through parallelization. Finally, I show that even when all of these conditions
are met (as in a vote-by-mail scenario), there are still wrinkles that must be
addressed for an election to be truly secure.PHDComputer Science & EngineeringUniversity of Michigan, Horace H. Rackham School of Graduate Studieshttp://deepblue.lib.umich.edu/bitstream/2027.42/163272/1/matber_1.pd
Sixth International Joint Conference on Electronic Voting E-Vote-ID 2021. 5-8 October 2021
This volume contains papers presented at E-Vote-ID 2021, the Sixth International Joint Conference on Electronic Voting, held during October 5-8, 2021. Due to the extraordinary situation provoked by Covid-19 Pandemic, the conference is held online for second consecutive edition, instead of in the traditional venue in Bregenz, Austria. E-Vote-ID Conference resulted from the merging of EVOTE and Vote-ID and counting up to 17 years since the _rst E-Vote conference in Austria. Since that conference in 2004, over 1000 experts have attended the venue, including scholars, practitioners, authorities, electoral managers, vendors, and PhD Students. The conference collected the most relevant debates on the development of Electronic Voting, from aspects relating to security and usability through to practical experiences and applications of voting systems, also including legal, social or political aspects, amongst others; turning out to be an important global referent in relation to this issue.
Also, this year, the conference consisted of:
· Security, Usability and Technical Issues Track
· Administrative, Legal, Political and Social Issues Track
· Election and Practical Experiences Track
· PhD Colloquium, Poster and Demo Session on the day before the conference
E-VOTE-ID 2021 received 49 submissions, being, each of them, reviewed by 3 to 5 program committee members, using a double blind review process. As a result, 27 papers were accepted for its presentation in the conference. The selected papers cover a wide range of topics connected with electronic voting, including experiences and revisions of the real uses of E-voting systems and corresponding processes in elections.
We would also like to thank the German Informatics Society (Gesellschaft für Informatik) with its ECOM working group and KASTEL for their partnership over many years. Further we would like to thank the Swiss Federal Chancellery and the Regional Government of Vorarlberg for their kind support. EVote-
