Quantum computing are breakthroughs aimed to revolutionize several sectors, although they also present considerable cybersecurity threats. Quantum computers can manage quite greater quantities of information than the most powerful conventional supercomputers and has the capability to do complex computations. Despite being in the early stages of development, quantum computers have the potential to be regarded as cybersecurity concerns. Quantum computing is a phenomenon that should be seen as a technology primed to facilitate significant innovations in the future, while also presenting different concerns. The quantum cybersecurity threat encompasses data breaches of sensitive health and financial information, challenges to the integrity of digital assets, and vulnerabilities in the encryption supporting cryptocurrencies, among other possible risks. This review paper focuses on quantum computing and its effects on different security methods in the present generation. It covers the quantum computer threats to cryptography, post quantum cryptography and a comparison of different approaches to cryptography.

The fundamental aim in the age of information technology (IT) and artificial intelligence (AI) is to ensure software or web application security. A security alternative provides a wide range of software security approaches and algorithms. To improve the security character, security evaluation is an important component for assessment, management, and control. Early security evaluation assists in distinguishing worms, hazards, weaknesses, and threats. We are aware of that. The current paper will discuss how quantum computing is defined and characterised in software security. We utilise many techniques or algorithms to safeguard our financial organisations, our medical equipment, our military weaponry, our aviation systems, our boats, vehicles, navigators, etc. in software security (cryptography is the science or art to build a data protocol). However, when the big quantum computer develops, many cryptosystems will certainly fail. The current encryption method is becoming outdated as the cryptographic technique may be resolved by quantum computers. Therefore, in the framework of the existing quantum safety, it is necessary to focus more on intensive study. The key challenges in the quantum age would be cryptography solutions that satisfy the need for security, usability, and adaptability without jeopardising user trust. This study focused on Grover’s work and how the security aspect of software may be improved. In the field of software and online applications, software security in quantum computing will be investigated, given the importance of security issues in the quantum computing age.
Software or web application security is the main objective in the era of Information Technology (IT) and Artificial Intelligence (AI). Distinguishing proof of security at the initial stage produces significant results to comprehend the administration of security relics for best potential outcomes. A security alternative gives several methods and algorithms to ensure the software security. Security estimation is the vital factor in assessing, administrating, controlling security to improve the nature of security. It is to be realized that assessment of security at early stage of development helps in identifying distinctive worms, dangers, weaknesses and threats. This paper will talk about the definition and characterization of quantum computing in software security. For software security, we use different cryptography (methods or algorithms to secure our financial organizations, medical devices, military weapons, planes, ships, automobiles, navigators, etc. However, many cryptosystems are likely to collapse when the large quantum computer is developed. Recently, Google developed the Sycamore Processor 53 qubits. Such innovations indicate the advent of large quantum computer in future. Since cryptographic algorithm can be solved by the quantum computers, the present cryptosystem would be rendered obsolete. Hence, it is imperative to focus more on intensive research in the context of the present quantum cyber security. The main challenges in quantum era would be cryptography methods that fulfill the demands of security usability and flexibility without sacrificing the users’ confidence. This research study, in particular, focuses on ‘Software durability’ which is a quality of security that alludes to the capacity to execution of an item on schedule. In the context of software and web application, a thorough assessment of security factors will significantly influence the software’s durability in the era of quantum computing.
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 rapidly shifting from high-tech lab to mainstream commercial use in the next few years, representing the next breakthrough in modern ICT. It is motivated by quantum computer's ability to perform computational tasks with efficiencies that are not possible with classical computers. Quantum computing technology has a lasting potential impact on society and broad implications on many aspects of our lives. Although quantum computing has several advantages, it threatens the security of current cryptographic techniques. It is expected that quantum computers will be able to solve the key distribution problem and break every single cryptography and authentication algorithm based on asymmetric cryptography. New emerging technologies such as the Internet of Things, blockchain, autonomous vehicles, 5G, artificial intelligence and robotics all rely on cryptography for their secure operation. Therefore, the realisation of quantum computing will pose significant challenges to the current progress and future development of these technologies. In this paper, the quantum technology preliminaries are discussed. The possible impact of quantum technologies on emerging technologies is investigated. Finally, some of the currently available quantum-safe cryptosystems devoted to protecting computer systems in the quantum era are discussed.
Quantum computing’s arrival signals a paradigm shift in computational power that may transform several sectors, including drug discovery, artificial intelligence, materials research, and optimization [2]. However, this transformative potential also presents a significant and imminent threat to cybersecurity. At the heart of this technological shift is the ability of quantum computers to tackle the complex mathematical challenges on which modern public-key cryptography relies. Quantum algorithms, most notably Shor’s algorithm, can break problems such as integer factorization and discrete logarithms far more efficiently than classical approaches. As a result, cryptographic methods that are widely trusted today—including RSA and Elliptic Curve Cryptography (ECC)—could become insecure once large-scale quantum computing becomes a reality[1], [8].This poses a profound challenge to the confidentiality, integrity, and authenticity of digital communications, financial networks, essential infrastructure, and national defense systems [9]. To counter this emerging risk, Post-Quantum Cryptography (PQC) has become an important area of active research. The goal of PQC is to design cryptographic techniques that can withstand attacks from both conventional computers and future quantum systems, thereby preserving long-term data security in the face of advancing quantum technologies [3].A number of promising Post-Quantum Cryptography (PQC) approaches are currently being explored in depth. Among them, lattice-based cryptography has attracted significant interest, as it relies on the computational difficulty of problems like Learning With Errors (LWE) and the Shortest Vector Problem (SVP), offering both robust security assurances and practical efficiency [4], [5]. Hash-based signature schemes, such as XMSS and SPHINCS+, offer security rooted in well-established hashing techniques and stateless signature construction [7]. Additionally, code-based cryptography, including systems inspired by the McEliece cryptosystem, remains attractive for its long-standing resistance to cryptanalytic attacks [6]. Other avenues include multivariate quadratic systems and isogeny-based cryptography, each presenting unique benefits and trade-offs in terms of key size, performance, and security robustness [8].A central force driving global standardization is the NIST Post-Quantum Cryptography Standardization Project, initiated in 2016 to evaluate and establish new quantum-resilient cryptographic standards [3]. Several algorithms have already advanced to the final standardization phase, while others remain candidates for further evaluation.Despite this progress, transitioning to PQC introduces practical challenges. Integrating new cryptographic algorithms into current digital ecosystems demands considerable computational and infrastructural updates, often involving larger key sizes and increased processing overhead [10]. Organizations must also ensure crypto-agility, the capability to rapidly adapt cryptographic systems as new standards evolve or vulnerabilities are identified [11].One strategic transition approach involves hybrid cryptographic architectures, which combine conventional and quantum-safe algorithms to provide layered security during this migration period [9]. Moreover, organizations should inventory existing cryptographic assets, conduct quantum risk assessments, pilot PQC deployments, and cultivate a quantum-aware cybersecurity workforce.The threat is amplified by “harvest now, decrypt later” strategies, in which adversaries intercept encrypted data today with the intention of decrypting it once quantum capabilities mature [9]. Particularly sensitive categories — including military communications, governmental archives, personal healthcare records, and intellectual property — require immediate PQC-oriented protection.As the quantum era approaches, coordinated global action is essential to harness quantum innovation while safeguarding digital trust. Through proactive investment in research, standardization efforts, and phased post-quantum deployment, societies can preserve digital sovereignty and security resilience in the face of this technological shift [11].
