Abstract Information security in communication networks is a persistent problem and essentially requires the usage of encryption methods. Quantum computing was first used to break encryption codes in the latter half of the 20 th century with the introduction of the SHOR algorithm. Though the recent developments in QC capabilities have increased confidentiality, integrity, and availability of networks by protecting them against passive attacks like eavesdropping yet the transformation of classical to quantum computation can bear catastrophic implications as it has the potential to put the currently secure methods of transactions in jeopardy. This paper aims at the evaluation and comparison of traditional cryptographic techniques by the application of a SWOT framework. It takes up an exploratory study of the advanced quantum computing capabilities that can pose a massive risk to network security. The various security enhancements that can be adopted in data transmission to curtail these risks post-quantum are also discussed.
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.
ABSTRACT The paper examines the rise of quantum computing and its implications for cybersecurity. Quantum computers, unlike classical ones, use principles of quantum mechanics, such as superposition and entanglement, to solve complex problems exponentially faster. This poses a threat to existing cryptographic systems, especially those based on public-key encryption like RSA and ECC, which could be vulnerable to quantum algorithms such as Shor’s algorithm. The document highlights the potential for quantum computing to break current encryption methods, putting sensitive data at risk from cybercriminals. To mitigate these risks, researchers are developing post-quantum cryptography and exploring quantum-resistant security measures, such as Quantum Key Distribution (QKD), to protect data in a future quantum-powered landscape. The paper emphasizes the urgency of updating encryption and cybersecurity strategies to prepare for the impending "quantum era." keywords Quantum computer Cyber security Cryptography Algorithm Digital signature Post-quantum cryptography Quantum key distribution Cyber attack Digital infrastructure Quantum mechanism Legacy systems Quantum era
