The integrity of electronic voting systems is critical in safeguarding the democratic process worldwide. This study addresses the twin challenges of bribery and coercion that undermine most existing electronic voting systems. Recognizing the limitations of current security measures, which fail to protect voter autonomy even after the disclosure of voting secrets, we propose an innovative level-five secure e-voting system. By integrating an additional setup phase, our system maintains voter volition, ensuring security even when key secrets are compromised. Utilizing cryptographic techniques, blind signatures, and subliminal channels in conjunction with smart card PIN mechanisms, our approach not only bolsters system security but also enhances its potential for widespread adoption. This work underscores the importance of advanced cryptographic methods in developing coercion-resistant electronic voting systems that prioritize voter privacy and choice.
