A VERIGIABLE MULTI-AUTHORITIES SECRET ELECTION ALLOWING ABSTAINING FROM VOTING

Abstract

In this paper, we propose a robust and verifiable multi-authorities secret voting scheme which meets the requirements of large scale general elections. This scheme uses a uniquely blind threshold signature scheme to get blind threshold electronic votes such that any voter can abstain from voting after the registration phases. It also uses the threshold cryptosystem to guarantee the fairness among the candidates' compaigns and to provide mechanism for achieving the function that any voter can make an open objecttion to the tally if his vote has not been published. In this scheme, the computations among voters are independent and voters only has to send an anonymous message to the counter after the registration phase. This scheme preserves the privacy of a voter against the counter, administrators, scrutineers, and other voters. Completeness, robustness, and verifiability of the voting process are ensured and hence no one can produce a false tally, corrupt or disrupt the election.
