Abstract This paper presents a voting scheme that allows voters to verify that their vote is accurately included in the count, whilst maintaining ballot secrecy and coercion resistance. It also presents a rigorously defined set of requirements for secret ballot voting, and proofs that the scheme satisfies these requirements.
