Secure Data Processing and Transmission Using AES and End-to-End Encryption in Cloud Environments

The Rapid expansion of cloud computing with data-centric services makes the protection of sensitive information via confidentiality, integrity, and availability indeed one of the most critical challenges. This work introduces a unified framework that integrates the advanced encryption standard (AES) with end-to-end encryption (E2EE) to secure data processing and transmission in a cloud environment. The proposal addresses security vulnerabilities that arise from multi-tenancy, third-party management, and remote access by encrypting data at the source and keeping its confidentiality throughout its lifecycle while it exists in the cloud. By using AES-CBC mode and a robust key-management scheme, the system guarantees secure data transmission, storage, and access control. Experimental evaluation indicates that the integrated AES-E2EE model reduces latency in comparison to traditional HTTPS (230 MS) and standalone AES (200 MS) significantly reaching dimensions as small as 175 MS, paving way for use in latency-sensitive applications. The results validate scaling, efficiency, and protection from present cyber threats of the proposed framework development towards building secure and trustworthy cloud computing infrastructures.
