How to Implement “Voting Mobility” in Brazilian Elections
Abstract
As eleições brasileiras apresentam uma taxa significativa de abstenção, situação comumente causada por viagens na data do pleito ou mudança recente de eleitores. Uma solução promissora é a “mobilidade na votação”, que permite ao eleitor votar em qualquer seção eleitoral. No entanto, as soluções atuais dependem tipicamente de conexão à Internet para prevenir votos duplos, algo problemático no cenário brasileiro. Assim, neste trabalho, são discutidas quatro alternativas para viabilizar a mobilidade na votação no Brasil. Embora nenhuma das soluções seja perfeita, nossos resultados indicam que a abordagem mais promissora é combinar o uso de hardware seguro com a remoção de votos duplos por meio de mixnets e threshold cryptography.References
