Optimizing the Application of Hybrid Cryptographic Methods for Secure File Storage and Retrieval

Abstract

In the modern digital era, the protection of sensitive data from unauthorized access is of utmost importance. A key concern in this regard is secure file storage. To address this issue, hybrid cryptography offers a viable solution by combining the strengths of various encryption techniques in both a vertical and horizontal manner. In hybrid cryptography, the original symmetric key is encrypted with a different symmetric key, while the actual data is encrypted using yet another symmetric key. This approach allows for quick and efficient encryption and decryption of the data, while also providing the added security of multiple encryption methods for authentication. By employing hybrid cryptography, organizations can ensure the secure storage of their critical data, safeguarding it against unauthorized access and potential data breaches.
