Cloud computing is the umbrella term for delivering services via the Internet. It enables enterprises and individuals to access services such as virtual machines, storage, or applications on demand. It allows them to achieve more by paying less, and it removes the barrier of installing physical infrastructure. However, due to its openness and availability over the Internet, the issue of ensuring security and privacy arises. This requires careful consideration from enterprises and individuals before the adoption of cloud computing. In order to overcome security issues, cloud service providers are required to use strong security measures to secure their storage and protect cloud data from unauthorized access. In this paper, a novel framework and symmetric-based encryption scheme for securing cloud data at rest is introduced. The performance evaluation of the new framework shows that it has a high level of efficiency, feasibility, and scalability.
