Zusammenfassung: | This paper studies several building blocks needed for electronic voting in order to prepare for the post-quantum era. In particular, we present lattice-based constructions for a generic zero-knowledge (ZK) proof of ballot correctness, a ZK proof of ballot correctness applicable for the homomorphic tallying scenario, and a ZK proof to achieve cast-as-intended verification during the vote casting period. We implement and benchmark our ballot correctness proofs, giving concrete estimations comparing the performance of homomorphic tallying and mix-net based e-voting systems in case of our lattice-based constructions. |
