Zero-Knowledge Proofs for Secure and Private Voting Systems

Abstract

As democratic processes increasingly transition to digital environments, safeguarding voter privacy and maintaining electoral integrity have become paramount. This study investigates the application of Zero-Knowledge Proofs (ZKPs) as a cryptographic framework for developing secure and private electronic voting systems. A comparative performance evaluation was conducted between ZKP-based voting protocols and traditional systems, focusing on key metrics such as validation time, privacy leakage index, and memory usage. Quantitative data analysis, supported by statistical methods including mean comparisons and standard deviation assessments, highlights the superiority of ZKP-based systems in minimizing information leakage while maintaining verifiability. Although ZKP protocols introduce higher memory consumption, the trade-off results in substantially enhanced voter anonymity and reduced validation latency. The findings suggest that ZKPs provide a scalable and efficient solution to the dual challenge of transparency and privacy in digital voting infrastructures. This research contributes to the growing body of work on cryptographic voting technologies and underscores the importance of balancing security with performance in the design of future e-voting systems.
