Developments in quantum computing may jeopardize the security of internet voting. Such developments could compromise important electoral requirements, including integrity, eligibility, or the secrecy of the vote. Even the contents of a vote cast online today, when quantum computers are not yet known to be available, could be revealed tomorrow. Countries are already working on a post-quantum setting, but elections seem to remain an exception. In this paper, we explore the existing strategies to mitigate the quantum threat or their lack thereof, as well as the views of different stakeholders on these matters. To do so, we have conducted a mix of desk research as well as interviews with 24 experts in different fields, from electoral administrations to cybersecurity agencies, vendors, and academia. We assess their perceptions about quantum computing, its impact on internet voting, and on transitioning towards quantum-resistant cryptography, as well as on interagency cooperation and trust issues. Whereas we initially assumed that elections were an exception in regards to the transition towards post-quantum cryptography, this research shows that the electoral field is neither alone nor the most adequate one to start the implementation of this kind of cryptography.

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. This paper outlines the roadmap for adopting quantum cryptography in voting systems and its potential impact on electoral integrity.
The rapid development of quantum computing is one of the most transformative technological developments of the twenty-first century with profound implications for cybersecurity, digital governance and the future of secure communication systems. Traditional cryptographic infrastructures have fundamentally underpinned digital trust in banking, healthcare, defense, cloud computing, and global communication networks, but the advent of quantum computational power has led to increasing concern about the future of existing standards for encryption. This qualitative study critically examines the changing relationship between quantum computing and post-quantum cryptography through an analysis of the technological, institutional, ethical and governance challenges in the transition to quantum-secure digital systems. The study adopts an interpretivist and exploratory qualitative orientation that aims to understand how governments, cybersecurity experts, technology institutions and policy frameworks are responding to the disruptive potential of quantum technologies. Data were collected using thematic analysis of academic literature, cybersecurity policy documents, archival technological reviews, expert commentaries, institutional reports, and emerging case studies related to the development of quantum-resistant cryptography. The results show that quantum computing presents serious threats to existing public-key cryptographic systems, especially in terms of theoretical abilities of Shor’s algorithm and future quantum decryption models. Meanwhile, the paper outlines post-quantum cryptography as a vital avenue for safeguarding digital privacy, institutional credibility, and cybersecurity robustness in an ever more networked society. The analysis also points to ongoing challenges around technological readiness, regulatory uncertainty, global standardization, resource inequality and ethical issues around surveillance, privacy and digital sovereignty. Yet, the research points to the potential for secure digital transformation, resilient cybersecurity governance, and the re-inventing of future communication infrastructure through post-quantum innovation. The research finds that the transition to quantum-secure systems is not just a technological challenge, but a multidimensional governance and policy challenge requiring international cooperation, ethical foresight and proactive institutional change.
As quantum computers advance, they will fundamentally change the ways the information systems that currently secure communications, financial systems, healthcare records, government databases and critical infrastructure are protected. Although quantum technologies offer great promise for future scientific endeavors and processing power, they also present new dangers for cybersecurity. This paper explores the threats that are emerging as a result of Quantum Computing, focusing on the vulnerability of popular public-key cryptographic methods like RSA, Diffie–Hellman and Elliptic Curve Cryptography. The study also delves into the consequences of "harvest now, decrypt later": Information encrypted today could be made available when sufficiently strong quantum computers are ready. The research adopts a qualitative approach with a thorough literature survey of scholarly works on quantum-safe security standards, international cybersecurity frameworks, and recent advancements in the field. It evaluates the readiness of organizations, governments and technology vendors to deal with the changing threats of quantum computing. The study also highlights emerging counter measures, such as post quantum cryptography, quantum key distribution, cryptographic agility, zero trust security architectures, and risk-based migration strategies to build long-term cyber resilience. The results indicate that while large-scale quantum computers are still being developed which could compromise current encryption systems, it is important to plan ahead and implement quantum-resistant technologies to mitigate future security risks. To achieve quantum-safe cybersecurity, a concerted effort is needed, involving a collaboration between policymakers, researchers, industry players and standardization organizations, to provide secure digital ecosystems. In the end, the paper argues that a blend of quantum-resistant cryptographic solutions and adaptive cybersecurity governance and continuous innovation will be a critical enabler in protecting information assets in the quantum era. The study will contribute to the existing body of work on quantum cybersecurity and provide insights into the challenges and opportunities of creating secure and future-proof cybersecurity systems.
Quantum computing is the future of computing with promised radical increase in processing capability; however, it is a threat the existing cybersecurity paradigm. Classical encryption techniques especially the ones based on public-key cryptography are insecure against quantum algorithms such as Shor’s algorithm where typical cryptographic schemes the use of which was exemplified by the RSA and ECC will be threatened. While torrents of research have been accomplished in building and developing quantum computers, the importance of post-quantum cryptography (PQC) becomes more felt. This paper attempts to look at the threats that quantum technologies pose to current cryptographic methods and the countermeasures that are being worked on to counter them. We do so to evaluate the current status on quantum computing and its ramifications to data security, as well as the work that academic and government institutions and business enterprises have done on coming with Quantum-Resistant Cryptography. In addition, the paper gives an overview of the most promising post-quantum cryptographic techniques including lattice cryptography, hash-based signatures, and code-based cryptosystems and cryptographic protocols that are under consideration as the next generation cryptographic protocols. It also tackles the problems related to the migration to the post-quantum cryptographic systems the problem of standardisation the problem of compatibility, and the problem of growth of new algorithms. Moreover, prescriptive advice on the concept of quantum readiness and timely implementation of cyber defence plans to safeguard sensitive data and crucial infrastructure against quantum risks is provided. Finally, the paper offers suggestions for the organisations for starting to transition to the post-quantum landscape in terms of using hybrid cryptographic systems and promoting cooperation in the fight against the threats of quantum technology world-wide.
In the age of digital transformation, the integrity and security of online voting systems have become a growing concern. Traditional cryptography methods are vulnerable to advances in quantum computing, demanding the need for more secure alternatives. This paper explores the application of quantum cryptography in enhancing the security of blockchain-based voting systems, a decentralized and transparent approach to conduct elections. We introduce a novel quantum-resistant voting protocol that integrates Quantum Key Distribution (QKD) with post-quantum cryptographic algorithms, ensuring secure voter authentication, vote casting, and tallying. The methodology combines quantum encryption with blockchain's immutability to create a tamper-proof voting ledger, preventing unauthorized access and vote manipulation. It gives an analysis of potential real-world implementations, positioning a hybrid quantum-blockchain framework as a promising solution for future secure electronic voting systems.
Abstract The implantation of Remote Electronic Voting (REV) systems to Electoral Processes is happening at a slower pace than anticipated. One of the relevant factors explaining that reality is the lack of studies about the Cryptographic Schemes and Primitives applied to the existing REV solutions. In this paper, the authors review the main cryptographic schemes applied to date, as well as the most relevant Post Quantum research in the field. The aim is twofold: contribute to clarify the strengths and weaknesses of each scheme as well as expose the remaining challenges, as a necessary step towards a broader introduction of REV solutions in binding elections.
