Abstract
Cloud computing provides scalable and costeffective data storage solutions, but it also introduces
significant security challenges such as data breaches,
unauthorized access, and insecure key management. To
address these issues, this paper proposes a Hybrid
Encryption-Based Automated Encryption/Decryption
System (AEDS) for secure cloud data storage. The
proposed framework integrates Elliptic Curve
Cryptography (ECC) for secure key exchange, Dynamic
AES (DAES) and DES for multi-layer data encryption, and
SHA-3 hashing for data integrity verification.
