Abstract

Many areas of human activities are computerized with the wide spread use of computers and communication networks. Electronic voting is an important social activity in democratic society. The realization of electronic democracy is based on the security of electronic voting scheme. Therefore, it is necessary to use the cryptographic technique for secure election. In this study, an electronic voting scheme suitable for large scale election is proposed. In order to make practical voting scheme, we assume that the voting authorization center is trustful and the Chaum''s anonymous communication channel[6] is prepared before the election day. The center authorizes the ballot of eligible voter by using the ID based digital signature scheme in the registration stage. During the voting stage, undeniable challenge/response protocol is performed between the center and the voters to ensure that the intermediate voting results should not affect the entire election. The proposed scheme fully conforms to the requirements of large scale election such as privacy of the voters, fairness, unreusability, unforgeability and eligibility.
