Cloud-Based Secure File Storage Using Hybrid Cryptography

In the era of pervasive cloud computing, ensuring the security and confidentiality of sensitive data stored on cloud platforms is a critical challenge. This paper proposes a “Cloud-Based Secure File Storage Using Hybrid Cryptography” system that leverages a novel hybrid encryption approach, combining symmetric and asymmetric cryptographic algorithms, to provide robust and efficient data protection. The proposed methodology involves dividing files into multiple segments, encrypting each segment with rotating encryption algorithms, and securing encryption keys through an additional encryption layer. This multi-layered security architecture significantly mitigates the risks of unauthorized access and data breaches, ensuring only authorized users can retrieve and decrypt stored files. The system also offers comprehensive administrative and user functionalities, including secure file upload, retrieval, and an integrated support FAQ, thereby enhancing both security and usability for cloud-based file storage.
