MultiBallot: Verifiable and privacy-preserving E-Collecting in the Swiss setting

Computer Science > Cryptography and Security [Submitted on 19 May 2026] MultiBallot: Verifiable and privacy-preserving E-Collecting in the Swiss setting Florian Moser, Léo Louistisserand As part of the political process, citizens may participate in signature collections to influence policy changes. In Switzerland, this even results in legally binding acts, similar to an election system. In this work, we first derive a realistic setting for e-collecting in Switzerland, based on the setting established for e-voting. Then, we propose a secure protocol in this setting, achieving both privacy and verifiability under realistic trust assumptions. Notably, participation privacy is guaranteed without assuming an anonymous channel, by considering the fact that at any given point in time, many collections are active in parallel.
