Post-Quantum Cryptography: Addressing the Future Threats to Cybersecurity

Abstract

Classical cryptography systems are vulnerable to quantum computing because they depend on computationally tough issues, such as solving discrete logarithms or factoring big integers. Cryptography in the age of quantum computing has new challenges and opportunities. Post-quantum cryptography (PQC) aims to address these issues by developing algorithms that are resistant to quantum computing, including code-based, hash-based, and lattice-based cryptography. The study sheds light on how PQC can tackle future cybersecurity risks by examining their security models, performance, and suitability for real-world implementation. The article also delves into the difficulties of updating the world's cryptographic infrastructure to use algorithms that are immune to quantum attacks, as well as the present status of PQC standardization initiatives. Protecting digital systems from possible breaches and guaranteeing long-term data security will be the deployment of PQC that is most important as quantum computing develops.
