Abstract
Online voting systems are gaining acceptance with the widespread use of secure web services and cloud computing such as electronic currency and online banking. However, they still face privacy, security and accountability issues. Designing a system that covers all the general requirements of secure voting is a research challenge. In this paper, we propose a secure online voting protocol based on a partially homomorphic encryption scheme. Our protocol ensures the anonymity of voters while preserving the integrity of the results. Experiments show the viability of our protocol in terms of both security and scalability.
