The promise of quantum computing is not speeding up conventional computing rather delivering an exponential advantage for certain classes of problems, with profound implications for cybersecurity for instance. With the advent and development of quantum computers, cyberspace security can surely become the most critical problem for the Internet in near future. On contrary, prosaic quantum technology can be promising to transform cybersecurity. This research aims to synthesize basic and fundamental studies concerning quantum cybersecurity that can be emerged both as a threat and solution to critical cybersecurity issues based on a systematic study. We provide a comprehensive, illustrative description of the current state-of-the-art quantum computing and cybersecurity and present the proposed approaches to date. Findings in quantum computing cybersecurity suggest that quantum computing can be adopted for the betterment of cybersecurity threats while it poses the most unexpected threats to cybersecurity. The focus and depth of this systematic survey not only provide quantum and cybersecurity practitioners and researchers with a consolidated body of knowledge about current trends in this area but also underpins a starting point for further research in this field.
The emergence of quantum computing is set to reshape the landscape of cybersecurity, presenting a blend of significant challenges and groundbreaking opportunities. This paper delves into the growing risks tied to quantum technologies, with a particular focus on post-quantum cryptography (PQC) and the threats posed by the possible obsolescence of traditional cryptographic methods. As quantum computing capabilities advance at a rapid pace, the need for the development of quantum-resistant security protocols has become more urgent than ever. This research investigates the vulnerabilities of current cryptographic systems, the potential dangers posed by quantum computing, and the solutions already available in the field of post-quantum cryptography. Furthermore, the paper outlines a comprehensive framework for cybersecurity solutions that are resilient to future quantum threats, emphasizing the importance of collaboration across academic, industrial, and governmental sectors. By reviewing current literature and technological developments, this paper provides a roadmap for transitioning to quantum-safe security practices, addressing the risks brought on by quantum advancements, and ensuring that critical infrastructure is well-defended against quantum-driven attacks. The findings indicate that while quantum computing introduces profound risks to traditional cybersecurity systems, a proactive, strategic adoption of PQC solutions can effectively protect vital infrastructure in the post-quantum age.
The advent of quantum computing represents a transformative leap in computational power, offering the potential to solve complex problems beyond the reach of classical computers. However, this power also presents significant cybersecurity risks, as quantum algorithms can potentially break widely used encryption methods, jeopardizing data privacy and secure communications. This paper presents a comprehensive review of emerging quantum-related cybersecurity threats and explores defense mechanisms designed to mitigate these risks. We examine both theoretical and real-world implications of quantum computing on cryptographic systems, highlighting recent developments in post-quantum cryptography, Quantum Key Distribution (QKD), and hybrid classical-quantum security solutions. This review aims to provide a foundational understanding of the threats quantum computing poses to cybersecurity and discusses current and future defenses essential for safeguarding digital infrastructure.
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.
The 21st century is confronting profound transformations driven by emerging technologies, notably quantum computing, which promises opportunities and risks. As industries and governments invest heavily in quantum capabilities, the looming threat of quantum computers compromising current encryption schemes has prompted the exploration of postquantum systems. This research surveys quantum technologies and reviews existing and proposed quantum policies, particularly cybersecurity, to address critical policy challenges encompassing full-spectrum quantum computing development. Our retrospective literature review and prospective analysis reveal that the research and innovation trajectory involving quantum computing technologies will mature within the next decade. With geopolitical actors gaining access to cloud-based quantum computers, more stakeholders will engage with these nascent technologies, presenting new opportunities and risks. We argue that misaligned proposals, not sufficiently aligned with strategic policy, could hinder the adoption of emerging technologies and undermine national security. This thesis analyzes and addresses these issues and provides recommendations to enhance quantum computing security analysis and reshape geopolitical policies to effectively counter the imminent threats to national security.
