With rapid development of computer science and network technology, the technology of electronic voting is widely applied in various fields. There are lots of security requirements in electronic voting such as privacy, verifiability, fairness and robustness etc. Previous works mainly discuss how to guarantee these requirements by using cryptographic tools, such as encryption, commitment etc. There, most works assume that parties are honest who will follow the protocol or malicious who will arbitrarily break the security of the protocol. In fact parties in real life are neither honest nor malicious, but instead they may consider the benefits when they decide to participate in voting. This paper discusses the motivations of parties to participate into voting towards the view of game theory. More specifically, motivations are quantized as the notion of utilities just as those in game theory. Then we prove how to assign people to have motivations to vote by achieving Nash equilibrium.
