An electronic voting scheme based on undeniable blind signature scheme

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. The electronic voting scheme based on undeniable blind signature scheme is proposed for providing anonymity of voters and ensuring that the intermediate voting results do not affect the entire election. In order to make practical voting scheme, we assume that the voting authorization center is trustful and the IP trace between the voting authorization center and a voter is not available. The proposed scheme fully conforms to the requirements of large scale election such as privacy, fairness, unreusability, unforgeability and eligibility.
