A Blockchain-Enabled Quantum Signature Scheme for Securing Consumer-Centric E-Voting Applications

Utilizing designated verifiers in consumer-centric electronic voting (CCEV) systems not only enhances confidentiality but also upholds authenticity, validates the accuracy of votes, and protects participants’ privacy. Besides, integrating blockchain technology offers a decentralized and tamper-resistant solution that addresses issues like the single point of failure of traditional CCEV systems. However, the emergence of quantum computing introduces new security threats to established blockchain-based CCEV systems. To ensure the confidentiality and integrity of the voting process, we suggest a quantum blockchain-enabled CCEV system with designated verification that employs principles such as quantum key distribution and the no-cloning theorem. The suggested framework combines quantum computing with blockchain to make CCEV safe and resistant to quantum attacks, and to lower the chance of tampering. The security analysis section showcases the security features offered by the proposed system, including designated verification, source hiding, and non-transferability properties. Furthermore, a detailed performance analysis demonstrates the potential of the suggested system based on computational and communication efficiency with other existing state-of-the-art protocols. Therefore, our system provides enhanced security features, making it more suitable and effective for CCEV.
