A Novel Magical Encryption Technique for Secure and Efficient Public Cloud Storage

Cloud computing uses massive data centers to provide on-demand access to shared computing resources. Customers who are unable to store large amounts of data locally can move it to cloud storage companies that provide scalable capacity. These virtualized storage systems, which are supported by different deployment and service delivery models, effectively manage data persistence and retrieval. But maintaining data privacy in these settings is still difficult. In order to improve cloud data security, this paper suggests a novel technique called ME (Magical Encryption). Repeated letters and spaces are methodically eliminated from plaintext during encryption, creating compact ciphertexts that drastically lower upload size and storage needs. By using deterministic decryption, the method improves confidentiality while preserving data recoverability. For cloud storage applications, ME provides a lightweight solution that strikes a balance between efficiency and security.
