Cloud storage solutions offer scalable and cost-effective data management; however, they also introduce security risks, including unauthorized access, insider threats, and economic denial of sustainability (EDoS) attacks. This paper presents an advanced dual access control system designed to enhance Encrypted data sharing and dynamic user revocation in cloud environments. The proposed approach utilizes Ciphertext-Policy Attribute-Based Encryption (CP-ABE) to maintain inputs Security and employs Intel SGX enclaves for secure access. Moreover, it incorporates controlled download permissions, adaptive attribute-based access control, and efficient revocation strategies. Performance analysis demonstrates the scalability, security, and efficiency of the framework in comparison to conventional access control mechanisms.
