2026-02-18
The paper addresses the challenging and timely issue of vote buying in electronic voting. Electronic voting is a well established process in modern democracies. However, problems such as vote buying continue to pose a significant challenge. This paper aims at addressing this issue by leveraging the novel concept of Anamorphic Encryption to enable voters to cast their original vote together with a hidden ``fake" one. In this way voters can pursue their true preferences unobstructed while providing a compliance proof to potential vote buyers. The security of our construction is proved through a formal security analysis, that considers powerful adversaries who aim at breaching user privacy and influencing votes. We believe that this innovation e-voting approach can enhance the overall security of e-voting systems and pave the way to avoid electoral manipulation.
