Credenciais de Votação baseadas em BIP para Protocolos de Votação Resistentes à Coerção
Resumo
Protocolos de votação resistentes à coerção dependem de credenciais para deterem ataques coercivos. Para isso, cada votante recebe uma credencial para votar e deve gerar credenciais falsas ao ser coagido. As credenciais, no entanto, são números grandes de difícil memorização. Isso dificulta a utilização desses protocolos em cenários práticos de votação. De forma a facilitar o emprego dessas credenciais, esse trabalho investiga a utilização do BIP-39 como base para credenciais mais práticas.Referências
