Abstract:

As cloud computing becomes a central part of everyday operations, securing these environments against growing cyber threats is increasingly critical. Traditional security measures are struggling to keep pace with the rapid development of new attack methods, particularly as quantum computing threatens to break existing encryption standards. This paper explores the integration of blockchain and quantum cryptography to address these challenges and strengthen cloud security. While blockchain offers a visible, unchangeable record that guarantees data integrity, quantum cryptography offers encryption methods that are resistant to assaults based on quantum mechanics, safeguarding transactions and communications. When combined, these technologies offer a hybrid security strategy that defends cloud systems against potential quantum computing vulnerabilities while simultaneously combating current cyberattacks. The essay also examines how this hybrid approach may assist in the creation of a more secure and resilient cloud infrastructure in the future, as well as the practical challenges of implementing this integrated strategy, such as scalability and computational efficiency.
