An electronic voting scheme based on homomorphic encryption and decentralization

Area of Science:

• Computer Science
• Cryptography
• Information Security

Background:

• Traditional paper-based voting has limitations in storage, transmission, and security.
• Existing electronic voting systems are vulnerable to malicious voting and ballot tampering.
• Ensuring the integrity and anonymity of electronic votes is a significant challenge.

Purpose of the Study:

• To propose a novel electronic voting scheme that addresses security vulnerabilities.
• To enhance the integrity, verifiability, anonymity, and uniqueness of electronic voting.
• To improve the computational efficiency of electronic voting systems.

Main Methods:

• Implementation of an electronic voting scheme utilizing Paillier homomorphic encryption.
• Application of dual-layer encryption and digital signatures to ballots.
• Leveraging decentralization to bolster the security of the voting process.

Main Results:

• The proposed scheme ensures voting results remain confidential until the election concludes.
• Ballots are protected through homomorphic encryption, voter signatures, and a second layer of encryption.
• Security analysis confirms the scheme's ability to guarantee completeness, verifiability, anonymity, and uniqueness.
• Performance analysis indicates a 66.7% improvement in computational efficiency compared to existing schemes.

Conclusions:

• The developed electronic voting scheme effectively mitigates risks associated with traditional and existing digital voting methods.
• The integration of homomorphic encryption and decentralization provides a robust and secure framework for electronic elections.
• The scheme offers significant improvements in security and computational efficiency, making it a viable solution for modern electronic voting.
