In the modern digital era, where cyber-attacks, data breaches, and digital spying threaten global security, conventional cryptographic systems face increasing challenges. The rapid development of quantum computing has amplified these threats by undermining the security foundations of classical encryption algorithms such as RSA (Rivest–Shamir–Adleman) and ECC (Elliptic Curve Cryptography), both of which depend on the computational hardness of factorization and discrete logarithmic problems. Quantum cryptography, rooted in the principles of quantum mechanics, introduces a transformative approach that ensures theoretically unbreakable security. This paper explores the theoretical foundations, current technological developments, challenges, and future prospects of quantum cryptography. It emphasizes the transition from mathematical security to physical security, highlighting quantum key distribution (QKD), quantum random number generation, and post-quantum cryptographic frameworks. The study concludes that quantum cryptography is not merely a futuristic ideal but a necessary evolution for safeguarding the digital future in a quantum-enabled world
Abstract With the recent advancements in quantum computing, there is a threat that today’s widely used digital encryption schemes will become vulnerable to cryptography-breaking quantum algorithms. In particular, today’s most widely used asymmetric encryption schemes will be the most vulnerable. On the other hand, it is likely that symmetric encryption and hashing schemes will remain robust even with the advent of powerful quantum computers of the future. In addition, today’s quantum computers are not powerful enough to implement the asymmetric cryptography-breaking algorithms; however, as quantum computers become more powerful and more research is put into these quantum algorithms, it is only a matter of years before the most widely used asymmetric encryption schemes of today are no longer secure. Therefore, a global effort being led by the National Institute of Standards and Technology (NIST) is underway to tackle this issue. As long as these efforts continue to progress at the current pace the potential adverse effects of these cryptography-breaking quantum algorithms are likely to be largely mitigated.
Abstract—Quantum computing is an emerging technology that significantly reduces calculation and processing time. Unlike classical computers that use binary bits with two states (0 or 1), quantum computers use qubits that can exist in two states simultaneously, known as superposition. Shor’s algorithm takes advantage of quantum parallelism to easily break RSA encryption algorithms, which are widely used in modern online services and encryption. This presents a threat to personal information and data security. This paper discusses the threat of quantum computing to current encryption algorithms and proposes new algorithms to prevent it.
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. This work also analyzes machine learning and AI in quantum security and its challenges and trends for the future. The literature review has incorporated references from more than 25 reputed Scopus-listed journal and conference proceeding.
Quantum computing has quickly become at the vanguard of many computer science fields today. This is motivated by quantum computers 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 a broad implications on many aspects of our lives. Communications Industry Researchers (CIR) estimates that the global quantum-computing market is expected to reach $1.9 billion in 2023, increasing to $8 billion by 2027, in spending on associated software and services. Although quantum computing has several advantages, it threatens the current cryptographic techniques, which are necessary for today’s Internet standards like the Transport Layer Security (TLS). This is due to its ability to perform infinite complex computations in parallel. Therefore, 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, such as: RSA, ECC, and Diffie-Hellman.
The rapid progress made in the domain of quantum computing has presented a number of opportunities as well as challenges in numerous domains, particularly in the domain of cryptography and security. The extraordinary computational capacity of quantum computing can be used to conduct computations at a much faster rate than classical computing, which makes quantum computing a potential threat to many cryptography systems. This paper presents a focused analysis of quantum computing’s influence on a cryptographic system and the digital data protection. This paper examines the basic concepts of quantum physics and discusses the challenges of classical cryptography protocols, along with the analysis of post-quantum solutions, focusing on the issues of secrecy, verification, and quantum security of these protocols. The evidence collected from various sources proves that quantum algorithms pose a threat to classical public-key cryptosystems; on the other hand, ML-KEM, ML-DSA, and SLH-DSA are the post-quantum solutions. It is imperative that a move to quantum-resistant encryption entails appropriate migration policies and standards alongside technological advancements. Such conclusions suggest that adequate preparedness can help in enhancing the security of encrypted information with advancing quantum technology. This study emphasizes the significance of hybrid cryptographic implementations and cryptographic agility in the changeover from classical cryptography to quantum cryptography security frameworks. Real-world implementation should strike a balance between security power and efficiency of computation among other considerations.
