As the reliance on cloud computing continues to grow, the security of sensitive data stored in cloud environments has become increasingly critical. This project presents a robust solution for enhancing cloud data security through the integration of Dynamic AES Encryption, Blockchain-based Key Management, and the Elliptic Curve Cryptography (ECC) algorithm. DAES encryption extends the traditional AES encryption by distributing the encryption process across multiple nodes in a cloud environment. This approach not only improves security by eliminating single points of failure but also enhances resilience against various cyber threats. By encrypting data using DAES before it is uploaded to the cloud, we ensure that only authorized users can access the sensitive information, maintaining confidentiality and integrity. To manage encryption keys effectively, this project utilizes a blockchain-based key management system. Blockchain technology provides a decentralized and tamper-proof ledger for storing and distributing encryption keys. Each key generation, usage, and access request is recorded on the blockchain, creating an immutable audit trail that enhances accountability and transparency. This decentralized approach mitigates the risks associated with traditional centralized key management systems, ensuring that keys are securely distributed only to authorized users.
