In today’s digital world, most of our personal, financial, and health data is stored online. This makes cybersecurity extremely important — but also more challenging. Recent cyberattacks like the one on Australia’s MediSecure show how weak security can lead to huge losses. Now, a new risk is emerging: quantum computers. These work very differently from classical computers and can break the encryption methods (like RSA and AES) that we currently use to protect online data. This paper explains how cryptography works, what types exist (symmetric and asymmetric), and why current systems may not survive in a world where quantum computers are common. It introduces powerful quantum algorithms like Shor’s and Grover’s, which can break RSA and weaken AES much faster using quantum computers than any normal computers. This shows the power of quantum computers. These developments have pushed scientists to create new encryption systems called Post-Quantum Cryptography (PQC), which are built to resist quantum attacks but still run on regular devices. The paper also explores how quantum computing is evolving — from early research in the 1980s to real working processors today — and how countries and companies are investing in this technology. It suggests that in the future, people may access quantum computers over the cloud, rather than owning them. Finally, this research shows that the rise of quantum computing is both a threat and an opportunity. It challenges us to update our security systems, but it also opens the door for new startups and careers in quantum-safe cybersecurity.
Machine learning, deep learning, probabilistic neural networks, blockchain, and other new technologies all demand extremely high processing speeds. A quantum computer is an example of such a system. Quantum computers may be accessed over the internet. This technology poses a significant risk, since quantum terrorists, or cyber criminals, coul be able to cause many problems, including bringing down the internet. The principles of quantum mechanics might be used by evil doers to destroy quantum information on a global scale, and an entire class of suspicious codes could destroy data or eavesdrop on communication. Quantum physics, however, safeguards against data eavesdropping. A significant amount of money is being invested in developing and testing a quantum version of the internet that will eliminate eavesdropping and make communication nearly impenetrable to cyber-attacks. The simultaneous activation of quantum terrorists (organized crime) can lead to significant danger by attackers introducing quantum information into the network, breaking the global quantum state, and preventing the system from returning to its starting state. Without signs of identifying information and real-time communication data, such vulnerabilities are very hard to discover. Terrorists' synchronized and coordinated acts have an impact on security by sparking a cyber assault in a fraction of a second. The encryption is used by cyber-criminal groups with the genuine, nefarious, and terrible motives of killing innocent people or stealing money. In the hands of criminals and codes, cryptography is a dangerous and formidable weapon. Small amounts of digital information are hidden in a code string that translates into an image on the screen, making it impossible for the human eye to identify a coded picture from its uncoded equivalents. To steal the cryptographic key necessary to read people's credit card data or banking information, cyber thieves employ installed encryption techniques, human mistakes, keyboard loggers, and computer malware. This new volume delves into the latest cutting-edge trends and the most up-to-date processes and applications for quantum computing to bolster cybersecurity. Whether for the veteran computer engineer working in the field, other computer scientists and professionals, or for the student, this is a one-stop-shop for quantum computing in cyber security and a must have for any library.
Cryptography is used broadly in the digital age, making our communications secure, ensuring our data is safe, and enabling secure transactions on which we rely daily. Our reality is connected, we send an email without thinking about all the underlying protocols, we buy online, and we check the weather on our fridge. Utilizations are countless and so is our exposure. Cryptographic systems keep us safe, a shield for our privacy and our fundamental rights. However, we have arrived at the dawn of a new age, the quantum computing era. Seen for a long as a theoretical emanation of quantum mechanics it gives the first baby steps in the real world, making the world as we know it less safe and more dangerous. Post-quantum cryptography is the paladin that is coming to the rescue but will it be up to the challenge of keeping our world safe.
For a long time, we have used cryptographic methods such as RSA and ECC to protect the information. They rely on hard mathematical problems that are too difficult for normal computers to address alone. Now, because quantum computers are starting to be used, we may need a new kind of security. Quantum computers have the ability to run algorithms like Shor’s algorithm which are much faster at cracking RSA and ECC compared to ordinary computers. If this happens, the security we have used for so long might not function properly anymore. Because of these issues, a novel form of security, called quantum cryptography, has been introduced. Instead of using equations from math, it operates by the odd laws of quantum physics. The rules of quantum physics, like the uncertainty principle and the no-cloning rule, allow sharing secret keys so that any outsider can be detected at once. It relies on Quantum Key Distribution (QKD) and the BB84 and E91 methods are used for this. Even so, quantum cryptography is not fully flawless. You need special computers, it costs a lot to set up and it isn’t available everywhere yet. For this reason, people are also creating post-quantum cryptography which defends against quantum threats using regular computers instead of quantum hardware. In this system, will see how different traditional and quantum cryptography are, where each one excels and what innovations are likely to protect our data in the future, especially as quantum computers get more capable.
Quantum computers are growing faster every year, and that progress puts today’s classical encryption at serious risk. Once these machines reach full power, staple protocols like RSA and elliptic-curve cryptography SSDs become tomorrow's digital lockpicks, threatening the secrecy of everyday online banking. In response, many researchers are rallying behind post-quantum cryptography (PQC), a fresh toolkit meant to shrug off quantum decoding tricks. This paper examines how prepared the banking world is for that shift, using a systematic review of literature, pilots, regulations, and benchmarks issued between 2018 and 2025. Results show firms are already alert, testing hybrid systems alongside NIST-approved lattice schemes such as CRYSTALS-Kyber and Dilithium on the road to safer financial transactions. Serious roadblocks linger, such as sluggish system speed, outdated code that cant easily swap algorithms, and a design process that ignores most users. On top of that, regulators and intergovernmental groups are stepping up to define what quantum-proofing looks like and when banks must do it. The paper therefore argues that hooking post-quantum cryptography into everyday banking is doable, and the industry cares about it, yet it still needs joint spending on new hardware, clear rules, and tutorials for customers. Suggested actions are to build crypto-agile platforms, roll out mixed classical-plus-quantum methods in the meantime, and get all players talking so that online and mobile payments stay safe, smooth, and ready for whatever the quantum future brings.
New developments in quantum computing have made people worry that current security methods could be broken by quantum attacks. Some mathematical problems are hard to solve, which is how traditional encryption methods like RSA and ECC keep their secrets safe. However, quantum computers might be able to solve these issues a lot faster than regular computers, which makes these methods less safe. Because of this threat, experts have been working hard to make post-quantum cryptography methods that quantum computers can't break. These methods are made to stand up to the strength of quantum algorithms and protect the privacy, integrity, and validity of private data even when quantum attackers are present. Lattice-based cryptography is a potential method for post-quantum encryption. Its security comes from the difficulty of certain lattice problems. Lattice-based methods are thought to be safe from threats from both traditional and quantum computers because they offer good security promises. Lattice-based cryptography is a flexible way to build different types of cryptographic primitives, like encryption, digital signatures, and key sharing protocols. The study of code-based cryptography, which is based on how hard it is to decode some error-correcting codes, is another important advance. Code-based methods have been around for a long time and have been studied a lot, which makes them a good choice for security after quantum computing. Code-based cryptography is also easy to use and has strong security features, which makes it a good choice for real-world situations. Multivariate polynomial cryptography is another possible choice for cryptography after quantum computing. The safety of this method depends on how hard it is to solve systems of multivariate polynomial problems. Multivariate polynomial methods might not be as secure as lattice-based or code-based cryptography, but they are interesting options for some situations and places with limited resources.
