Practical Electronic Voting Scheme for Real World Environments

SUMMARY In this paper, we propose a practical and secure electronic voting scheme which meets the requirements of large scale general elections. This scheme involves voters, the administrator or so called the government and some scrutineers. In our scheme, a voter only has to communicate with the administrator three times and it ensures independence among voters without the need of any global computation. This scheme uses the threshold cryptosystem to guarantee the fairness among the candidate's campaign and to provide mechanism for achieving the function that any voter can make an open objection to the tally if his vote has not been published. This scheme preserves the privacy of a voter against the administrator, scrutineers, and other voters. Completeness, robustness, and veriiability of the voting process are ensured and hence no one can produce a false tally, corrupt or disrupt the election.
