As cloud computing continues to change, maintaining strong data security is still a major concern, especially in light of growing threats to encryption and key management systems.In order to overcome these vulnerabilities, this study proposes a novel, two-phase method that combines blockchain-based key management with dynamic Advanced Encryption Standard (AES) encryption.Our system uses dynamically generated AES keys for every file, in contrast to conventional static encryption techniques, reducing the possibility of widespread data compromise in the case of a key breach.In addition, blockchain technology is used to decentrally and impenetrably store encryption keys and other critical metadata, guaranteeing improved availability and integrity.To improve data security even more, Elliptic Curve Cryptography (ECC), a thin yet effective security layer, is implemented for safe key transmission and file exchange.The suggested methodology dramatically lowers attack surfaces in cloud environments by doing away with the need for centralized key storage and using dynamic encryption.Its scalable and modular architecture enables smooth interaction with current cloud infrastructures, providing businesses and people with an adaptable, future-ready solution for protecting sensitive data in the cloud.
