On the Security of Condorcet Electronic Voting Scheme

摘要

In this paper, we focus on the Condorcet voting scheme in which each voter votes with the full order of the candidates according to preference, and the result of the election is determined by one-on-one comparisons between each candidate. We propose the Condorcet electronic voting scheme that is secure, universally verifiable and satisfying one-on-one comparison privacy. Furthermore the result of the election can be determined without revealing the order of the candidates which each voter specified. We use a matrix to represent the order of all the candidates according to preference, and satisfy one-on-one comparison privacy using homomorphic property.
