Recent advancements in quantum technology have sparked serious concerns about the security of conventional encryption systems. The immense processing power of quantum computers presents a growing threat to algorithms that are currently deemed secure. These algorithms, which rely on computational complexity to ensure the safeguard sensitive data, can be easily compromised by quantum machines, jeopardizing the confidentiality and integrity of digital communications. In response, the "store now, decrypt later"strategy has emerged, where data is encrypted and stored now, with plans to decrypt it in the future using quantum computers. This highlights the urgent need to develop new cryptographic methods that can withstand quantum attacks, which are vital for ensuring the continued security of digital communications. This paper consists of identifying and presenting already standardized post-quantum encryption algorithms, investigating their theoretical foundations, potential resources and applications. In addition to raising awareness of the imminent risks posed by quantum computing, the study provides recommendations for web developers on how to integrate post-quantum cryptographic solutions, helping to guide the transition to more secure and resilient systems.
The internet is evolving—from sharing information (Web 1.0) to exchanging value (Web 2.0). Blockchain technology, also known as distributed ledger technology, is powering this transformation. By using a network of computers, cryptography and irreversible records, blockchain enables secure and transparent transactions without intermediaries. This unlocks the potential to streamline the transfer of digital assets like money, intellectual property, and more, revolutionising industries. Blockchain's rapid rise is fuelled by global investments and a surge in government and corporate innovation. It offers the promise of digitised records, reduced costs, real-time solutions and even greater efficiency and transparency in governance. However, challenges exist alongside these benefits, including the need for regulatory frameworks and adaptation to the potential threats posed by quantum computing. The development of quantum-resistant blockchain solutions will be crucial to ensure security as this technology matures. Like all powerful technologies, blockchain's impact depends on how it's implemented—offering both transformation and potential for disruption.
