Practical Quantum-Safe Voting from Lattices, Extended

Authors: Ian Black, Emma McFall, Juliet Whidden, Bryant Xie, Ryann Cartor


E-voting offers significant potential savings in time and money compared to current voting systems. Unfortunately, many current e-voting schemes are susceptible to quantum attacks. In this paper, we expand upon EVOLVE, an existing lattice-based quantum-secure election scheme introduced by Pino et al. We are able to make these expansions by extending the dimensions of the voter’s ballot and creating additional proofs, allowing for applicability to realistic election schemes. Thus, we present our system of schemes, called EVOLVED (Electronic Voting from Lattices with Verification and Extended Dimensions). We present schemes for numerous different types of elections including Single-Choice Voting, Borda Count, and Instant Runoff.
