Consequently, this information requires a robust transmission and protection system. In this work, we propose a system for the transmission of satellite images using a crypto-system based on the AES-GCM method, also, a transmission technique focuses on OFDM, which is a proven and simple solution to implement. Finally, we are interested in experimental results such as statistical tests and differential tests showing the effectiveness of our method.frImage Encryption, Key, AES-GCM, satellite image, image transmissioncryptage d’image, clé, AES-GCM, image satellitaire, transmission d’imageThesis
