An efficient quantum-resistant undeniable signature protocol for the E-voting system

The Internet technology's rapid development makes electronic voting become an important way to ensure democracy and fairness during the election process. Compared with manual voting, electronic voting mainly relies on mobile terminals and Internet technology. Therefore, it can effectively avoid manual errors and guarantee the authenticity of the voting result. Although lots of electronic voting systems have been constructed, cryptographic protocols in these systems are vulnerable to attacks from the quantum computer. Therefore, an efficient quantum -resistant undeniable signature protocol for the electronic voting system is proposed in this paper, which is based on the Fiat-Shamir signature framework. The proposed undeniable signature protocol not only ensures the integrity of voting results but also allows voters to decide the time when the verification process happens. Additionally, the random oracle model is utilized to analyze the security of our protocol. We also make a detailed performance analysis to show the potential value of this protocol in electronic voting.
