Cibersegurança na Computação Quântica

Abstract

As technology advances, there is a constant drive to improve performance, by means of parallel techniques, concurrency or improvements in physical configurations such as processors and memory. As an alternative to the classical computing model, techniques based on quantum systems, such as the polarization of photons, have been proposed. Quantum computing are subject to the same criteria with regard to cybersecurity, but current defense techniques are based on mathematical security, that is, on problems hard to be solved by current computers. However, those problems can be easily solved in quantum systems. This would easily break most encryption algorithms in use today. New cyber defenses are required to ensure data protection in the quantum computing. Therefore, we investigate security attack methods on quantum computing systems as well as the cryptographic algorithms that have been proposed for this scenario. Thus, our work reveals state-of-the-art of cyber security in the context of quantum computing
