Ensuring the security and integrity of voting systems is crucial for maintaining democratic processes. With the rise of cyber threats targeting electronic voting, traditional cryptographic methods are proving inadequate in safeguarding against sophisticated attacks. Quantum cryptography, particularly Quantum Key Distribution (QKD), offers a promising solution to enhance the security of voting systems by leveraging the principles of quantum mechanics. This research explores the application of quantum cryptography in secure voting, highlighting its potential to address vulnerabilities in current systems. The study examines the technological, practical, and legal challenges of implementing quantum-based voting systems, including infrastructure requirements and public acceptance. Furthermore, it assesses how quantum cryptography ensures voter privacy, prevents tampering, and provides robust protection against future quantum computing threats. While significant hurdles remain, the integration of quantum cryptographic techniques presents a transformative opportunity to create more secure and transparent voting processes.

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.
The rapid advancement of internet technology has raised attention to the importance of electronic voting in maintaining democracy and fairness in elections. E-voting refers to the use of electronic technology to facilitate the casting and counting of votes in elections. The need for designated verification arises from concerns about voter privacy, auditability, and the prevention of manipulation. Traditional e-voting systems use cryptographic techniques for security but lack verifiable proof of integrity. Integrating e-voting with a quantum designated verifier could address these challenges by leveraging the principles of quantum mechanics to enhance security and trustworthiness. In light of this, we propose a quantum e-voting scheme that uses a designated verifier signature. To ensure the confidentiality and authenticity of the voting process, the scheme uses quantum features like the no-cloning theorem and quantum key distribution. The proposed scheme has security properties like source hiding, non-transferability, and message anonymity. The proposed scheme is resistant to many quantum attacks, such as eavesdropping and impersonation. Due to designated verification, the scheme minimizes the risk of tempering. This paper provides a detailed description of the proposed scheme and analyzes its security properties. Therefore, the proposed scheme is efficient, practical, and secure.
This paper explores the integration of quantum cryptography and blockchain technology to address two pressing challenges: securing financial transactions in Central Bank Digital Currencies (CBDCs) and combating the spread of misinformation during U.S. elections through decentralized social media platforms. As quantum computing advances, traditional encryption methods may become obsolete, posing significant risks to digital financial systems. Quantum cryptography, with its quantum-resistant algorithms, offers enhanced protection for CBDC transactions, ensuring long-term security and privacy. Simultaneously, blockchain-based social media platforms provide a decentralized structure that can prevent the dissemination of false information by ensuring transparency and authenticity through cryptographic verification and consensus mechanisms. These platforms also facilitate decentralized identity management, empowering users to verify content without relying on centralized authorities. By combining quantum cryptography’s secure framework with blockchain’s decentralized transparency, this dual approach creates a more secure digital ecosystem that not only safeguards financial transactions but also strengthens democratic processes. The paper further addresses the regulatory and technical challenges associated with implementing these technologies and their potential to shape a more secure, transparent, and accountable future.
The concept of blockchain technology has transformed the digital ecosystem to allow decentralized, transparent and immutable transactions in various sectors. Its security is closely dependent on classical cryptography like ECDSA and RSA to perform digital signatures and SHA-256 to achieve consensus, which are becoming more susceptible to quantum computing. The cryptographic principles underpinning blockchain could be compromised with the emergence of the quantum algorithms of Shor and Grover, endangering the integrity of transactions, authentication and consensus protocols. This paper discusses the implications that quantum computing could have on blockchain security, analyses vulnerabilities of current cryptographic primitives and assesses post-quantum cryptographic (PQC) protocols, including lattice-based protocols, hash-based protocols, and code-based protocols. To guarantee backwards compatibility, as well as a gradual upgrade process to quantum-resistant protocols, a hybrid migration approach that involves transactions with two signatures is suggested. Experimental analysis shows that PQC integration attains reasonable performance trade-offs, that preserve verification costs, block size growth, and throughput effects within feasible limits, and that zero-loss resilience is achieved during reorganization tests. The conclusion is that blockchains with PQC support can reach post-quantum levels of security without major operation interruption, and they provide a viable roadmap to moving towards distributed ledger systems that are future-ready.
In a traditional voting system, voters have to reach the voting system to cast their votes. It is difficult for the elderly and for those living in remote localities to cast a vote. In the era of digital advancements, remote electronic voting has emerged as an efficient means of engaging citizens in decision-making processes. However, ensuring fairness and mitigating fraud in elections remain significant challenges. This research paper proposes a novel approach called Quantum Secret Sharing (QSS) combined with the quantum binary voting protocol, leveraging the capabilities of the IBM Quantum Experience platform. By incorporating established security features and introducing new criteria, this protocol aims to surpass the limitations of classical voting systems. The research involves the creation of communication circuits using IBM Quantum Experience and subsequent analysis through quantum state tomography. By integrating the principles of QSS and the quantum binary voting protocol, the proposed approach addresses the limitations of classical voting systems. The protocol satisfies the standards of traditional voting systems while introducing new criteria to overcome their shortcomings. Through the utilization of IBM Quantum Experience, secure communication circuits are established, and the outcomes are analyzed using quantum state tomography, ensuring the fairness and accuracy of the voting process. It integrates quantum cryptography, quantum communication, and classical cryptography techniques to create a robust and tamper-resistant voting protocol. By employing quantum superposition, the protocol enables voters to cast their votes in multiple states simultaneously, making it extremely difficult for a malicious person to intercept or alter individual votes. Furthermore, quantum entanglement ensures that any unauthorized attempt to measure or manipulate the quantum states would result in detectable changes, enhancing the overall security of the voting process.
