As cloud computing continues to gain popularity, concerns over the security and efficiency of data storage in cloud environments have become increasingly important. This paper proposes a framework for secure and efficient data storage in cloud computing environments. The framework integrates encryption, access control, and data management techniques to ensure the security, integrity, and accessibility of stored data. We discuss several key management and encryption strategies that can be used to protect data both in transit and at rest. Additionally, we examine access control mechanisms that can be used to restrict access to data based on user roles and privileges. We also propose a data management strategy that takes advantage of the clouds elastic storage capabilities while minimizing storage costs. Finally, we evaluate the effectiveness of our framework through simulations and experiments, demonstrating that it provides a secure and efficient data storage solution for cloud computing environments.
