Quantum computing and machine learning for cybersecurity: Technologies, challenges, and future perspectives

Swathi Terli, Jyothi Satya Bhavani Banisetti, Veera Satya Vineela Dokala

The cybersecurity is confronted with new challenges due to the increase in cyberattacks in terms of their cleverness, speed, and lack of detection. The traditional security systems tend to be slow in countering the sophisticated attacks. Simultaneously, quantum computing is establishing opportunities and risks in regards to security. The paper reviews the literature on quantum computing and machine learning as approaches to enhancing cybersecurity and also explores the difficulties arising with quantum technologies. The paper is conducted based on the PRISMA framework to conduct the search, filtering, the assessment, and synthesis of recent studies on key scientific databases. According to the results hybrid quantum-classical computing and Quantum Neural Networks can enhance intelligent threat detection, predictive analytics, cyber risk assessment, security automation and autonomous security systems. The analysis also shows some key weaknesses, such as the lack of quantum hardware, quantum error correction issues, high computations, the absence of standard security frameworks, privacy issues, and the paucity of practical deployed research. The paper emphasizes that machine learning and quantum computing used together would make cyber resilience, aiding secure computing, enhancing digital forensic, and speeding up further cybersecurity innovation. It is; the review concludes that future studies in Energy in Quantum Security, Quantum-Resistant Security, Zero Trust Security and intelligent cyber defense systems will be important in creating safe, all-scale, and responsive cybersecurity infrastructures in the digitalized environment of the future.

Cybersecurity in the Age of Quantum Computing: Emerging Threats and Solutions

Christian Manna Guimma

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

Swathi Mummadi, Sabiha Fathima

The advent of quantum computing marks a transformative era in technology, presenting both unprecedented opportunities and significant threats to the field of cybersecurity. This chapter explores the intricate relationship between quantum computing and cybersecurity, offering a comprehensive analysis of its dual impact. We begin with an overview of quantum computing fundamentals and also discussed the current cybersecurity landscape including quantum-enhanced cryptography, Quantum Key Distribution (QKD) and post-quantum cryptographic solutions, advanced threat detection capabilities, and securing emerging technologies like the Internet of Things (IoT). Case studies and real-world implementations of quantum-safe technologies are analyzed to provide practical insights into combating quantum threats and leveraging quantum advantages. Finally, we discuss the future outlook for quantum computing in cybersecurity, addressing anticipated advancements, potential timelines for large-scale quantum threats, and the collective efforts required to ensure a secure quantum future.
