AMVchain: authority management mechanism on blockchain-based voting systems.

Area of Science:

• Computer Science
• Information Security

Background:

• Blockchain technology offers transparency and immutability for electronic voting systems.
• Existing blockchain voting systems face challenges with data privacy and potential tampering.
• Voter privacy and candidate information security are critical concerns in electronic voting.

Purpose of the Study:

• To develop a secure, efficient, and decentralized blockchain-based electronic voting system.
• To address privacy disclosure and data tampering issues in blockchain voting.
• To propose a novel system, AMVchain, with robust access control and privacy-preserving mechanisms.

Main Methods:

• Implemented a three-layer access control architecture using smart contracts for permission management.
• Utilized linkable ring signatures to ensure ballot privacy during the voting process.
• Introduced proxy nodes to balance efficiency and concurrency in the system.

Main Results:

• AMVchain demonstrates a fully decentralized and efficient blockchain-based voting solution.
• The system effectively protects ballot privacy and manages access control.
• Experimental results confirm the system's capability to handle high concurrent user loads.

Conclusions:

• AMVchain successfully overcomes the limitations of traditional blockchain voting systems.
• The proposed authority management and privacy-preserving techniques enhance election security.
• The system provides a viable solution for secure and efficient decentralized electronic voting.
