A Novel Approach to Data Security in Cloud Storage using Erasure Coding and Re-Encryption

The widespread adoption of cloud storage systems raises concerns regarding data confidentiality, particularly when data is stored on external clouds. Encryption techniques can protect data privacy but often impose limitations on storage system functionality, especially in decentralized distributed systems. This research study proposes a novel solution to address these challenges by combining a re-encryption algorithm with decentralized erasure coding. The proposed system enables users to forward their data to others without requiring decryption, ensuring reliable and secure data storage and retrieval. The primary technical contribution of this research lies in the development of a re-encryption system that facilitates both encryption and forwarding operations over encrypted and decrypted communications using the Blowfish algorithm. This innovative approach enhances data confidentiality and flexibility in decentralized cloud storage environments. By addressing the limitations of existing encryption techniques, this research contributes to the development of more secure and efficient cloud storage solutions, providing users with greater control over their data and ensuring its privacy and integrity.
