In the quickly developing field of cloud computing security, this study presents novel approaches to ongoing problems. It suggests all-encompassing methods for protecting private information kept on cloud servers, making use of blockchain-based key management and dynamic AES encryption keys for improved security and decentralized governance. Furthermore, without jeopardizing user privacy or disclosing confidential data, a privacy-preserving verification scheme guarantees the integrity of deep packet inspection services in untrusted clouds. Furthermore, a Searchable Encryption that Preserves Privacy (PPSE) method ensures data security and privacy while facilitating effective keyword searches over encrypted data by utilizing both public and private blockchains. To address worries about cloud data security, these systems include strong encryption, decentralized key management, and defense against illegal access. In modern cloud systems, they guarantee users' data security by offering scalable and flexible solutions.
