Quantum computing poses a significant threat to classical cryptographic algorithms, particularly the Advanced Encryption Standard (AES). This study investigates the impact of Grover's algorithm on the AES S-box, a fundamental component of the AES encryption process. By leveraging quantum mechanics, Grover's algorithm can potentially reduce the time required to break AES encryption from 2128operations to 264operations, thus presenting a substantial security risk. This research aims to evaluate the feasibility of such quantum attacks on AES S-box by conducting experiments using virtual quantum simulators. The study examines the resource requirements, including the number of gates and qubits, and assesses the scalability of Grover's algorithm across different data sizes and types. The findings indicate that, while theoretically effective, the practical implementation of Grover's algorithm is currently hindered by significant resource constraints on existing quantum hardware. These results underscore the need for continued advancements in quantum technology and the development of quantum-resistant cryptographic methods to ensure data security in the quantum era. This research contributes to the understanding of quantum vulnerabilities in classical cryptography and supports the development of robust encryption strategies that can withstand future quantum attacks.
