Electronic voting (e-voting) is no longer a theoretical ideal—it is increasingly becoming a part of real-world electoral processes across the globe. In a recent expert interview, Dr. Elizabeth A. Quaglia, a leading cryptographer and researcher at Royal Holloway, shared valuable insights into the current landscape, technical challenges, and future potential of e-voting systems.
With over 15 years of experience in cryptography, Dr. Quaglia’s work focuses on public key encryption, anonymity-enhancing protocols, and the design of provably secure and coercion-resistant e-voting systems. This article summarizes the key takeaways from her interview, shedding light on both the technical and human aspects of building trust in digital democracy.
Defining Privacy in E-Voting: Beyond Ballot Secrecy
Dr. Quaglia emphasized the importance of precise definitions of privacy in e-voting. While ballot privacy—ensuring that a vote remains secret—is a foundational concept, her research delves deeper into receipt-freeness and coercion resistance.
- Receipt-Freeness: Prevents voters from obtaining proof of how they voted, which is crucial to stopping vote-buying.
- Coercion Resistance: Ensures that voters cannot be forced or persuaded into revealing or altering their vote under pressure.
Her work aims to formalize these privacy properties and design e-voting protocols that meet these stronger guarantees while remaining practical for real-world use.
Building Provably Secure Voting Systems
Cryptographers play a key role in establishing formal security definitions and then designing systems that can be mathematically proven to meet these criteria. Dr. Quaglia is particularly interested in making these protocols more efficient, scalable, and less dependent on strong trust assumptions.
One exciting direction in her work includes adapting secure e-voting schemes for use in other fields, such as secure online auctions—demonstrating the broad applicability of robust cryptographic designs.
Real-World Status: E-Voting in 2024 and Beyond
With half the global population voting in 2024, including countries like India, Indonesia, the UK, and the US, e-voting is undeniably relevant. Many regions, such as India, already use electronic voting machines (EVMs) on a large scale.
However, Dr. Quaglia notes that the gap between theoretical security and deployed systems remains significant. Bridging this gap involves collaboration between researchers, policymakers, and implementers, and increasing trial-based adoption of advanced cryptographic protocols.
Barriers to Adoption: Trust and Scalability
According to Dr. Quaglia, the two primary barriers to wider e-voting adoption are:
- Lack of Trust in Technology:
- Skepticism towards software, hardware, and the organizations managing the election.
- Need for transparency, usability, and public understanding of how e-voting systems work.
- Scalability Challenges:
- Many academically secure schemes struggle with performance when scaled to millions of voters.
- The need for systems that are both secure and efficient remains a core research challenge.
The Path Forward: Context-Aware E-Voting Solutions
Looking ahead, Dr. Quaglia emphasizes the importance of context-specific solutions:
“There won’t be a one-size-fits-all solution for e-voting. Each culture, electoral system, and setting may need a tailored approach.”
Her vision includes stronger collaborations between technical experts and election stakeholders, greater public education, and ongoing field trials to refine these technologies before widespread deployment.
She encourages a balanced view—neither completely for nor against e-voting—but rather a pragmatic, research-informed stance that values usability, inclusiveness, and trust.
A Dream for the Future: Usable, Secure, and Verifiable E-Voting
Dr. Quaglia’s ideal outcome?
“A fully coercion-resistant, end-to-end verifiable e-voting scheme that’s easy to use—and that people trust because they understand how it works.”
This dream aligns with broader goals in cybersecurity: ensuring systems are not only secure in theory, but also accessible and acceptable in practice.
