Cipherion - An Elliptic Curve Cryptography-Based System for File Transmission

Cipherion is an Elliptic Curve Cryptography-based system designed for secure and efficient file transmission. While traditional methods like RSA provide security, they often impose high computational demands. Cipherion addresses this by utilizing Elliptic Curve Cryptography (ECC), which offers equivalent security to RSA with significantly lower overhead. The system employs a hybrid encryption approach: file contents are encrypted using symmetric algorithms (AES, DES, or ChaCha), while ECC facilitates the secure exchange of symmetric keys via the Elliptic Curve Diffie–Hellman (ECDH) protocol. Implemented in Python, the system features a modular design including file validation, key generation, and secure transfer components. Optimized for resource-limited environments such as IoT and mobile platforms, Cipherion provides a lightweight, scalable solution for robust file security.
