IEEE Symposium on Security and Privacy 2024 · Day 3 · Continental Ballroom 6
This talk, presented by Rosario Giustolisi, Maryam Sheikhi, and Carsten Schuermann at IEEE S&P, introduces a novel technique designed to enhance the security and integrity of internet-based voting systems by providing robust **last-minute voter coercion resistance**. Internet voting, while offering unparalleled convenience by allowing ballots to be cast from personal devices, inherently introduces complex challenges related to vote privacy, verifiability, and crucially, resistance to coercion. The presentation meticulously details a new approach that addresses a significant gap in existing cryptographic voting schemes, specifically the vulnerability to coercion attempts that occur immediately before or during the act of voting.

This research introduces a novel, cryptographically robust technique to counter last-minute voter coercion in internet voting. By integrating dynamic credentials, server-generated noise ballots, and an innovative voter-server signaling mechanism, it effectively enables voters to cast true ballots under duress while eliminating the need for a trusted registration authority. The solution is practically efficient, demonstrating scalability for large-scale elections.
