Fortidrop: Cloud-based secure file-sharing tool using Cryptography

Abstract

The increasing prevalence of data breaches and cyber risks has made secure file sharing a crucial requirement in today's digital world. A cloud- based file-sharing solution has been developed, employing various cryptographic techniques to address this. This tool ensures the secrecy, integrity, and authenticity of shared files. It utilizes symmetric encryption to encrypt file contents, allowing only authorized users with the decryption key to access the file. Asymmetric encryption is used to securely share the decryption key, while digital signatures verify the integrity and authenticity of transferred files. Robust authentication technologies, such as multi-factor authentication, and role-based access control are implemented to ensure authorized user access and manage permissions. End-to-end encryption further enhances security by encrypting files on the sender's device and decrypting them on the recipient's device without intermediary server involvement. This technology significantly improves the security and privacy of shared files, reducing the risk of data breaches and unauthorized access.
