Abstract

In this paper, we introduce a novel internet voting protocol which satisfies all desired security requirements of electronic voting system. The main contribution of the newly proposed protocol is the ability to debate more powerful adversaries than any previous works. In particularly, they can force voters to follow their wish, collude with one or more voting authorities to get the contents of votes or to destroy the voting system. To against these kinds of adversaries, blind signature and dynamic ballots techniques are employed instead of complex cryptographic one such as homomorphic encryption and mix-net. Moreover, we also aim at a practical system by improving the blind signature scheme and removing physical assumptions. Finally, with blind signature and dynamic ballots, we will present an enhancement of protocol which is unsusceptible to most of sophisticated attacks.
