Abstract: In the fast-growing sector of cloud computing, users can employ system resources as needed for data storage and computation. Protecting confidential data is the biggest cloud computing challenge. Security challenges in cloud computing are categorised as network, data, software, infrastructure, identity, and access management. Data concerns typically arise with cloud computing: data loss, dependability, availability, breaches, backup, and ownership. Cloud service companies worry about security and privacy when hosting services. Cloud storage data security can be improved in many ways. Cloud storage encrypts data for maximum protection. Layered encryption improves cloud data security. Scrambling and binary logical operation are used in the two-layered encryption method. Data is separated into square matrix shares on the first layer. This layer swaps the square matrix using scrambling. The second layer turns the scrambled matrix to binary, and the XoR logical operation encrypts it. The AWS cloud stores encrypted data. The algorithms provided great security, reduced cipher text size, and shortened encryption and decryption time compared to previous encryption methods.

Keywords: computing critical systems; data security; data encryption; layered encryption; cloud computing; cloud security; scrambling; cryptography; data storage.
