Transmission of images from satellite to ground is exposed to threats that can damage the confidentiality of data. The Advanced Encryption Standard (AES) is slowly emerging in modern space missions. In this paper, a modification to the AES-Counter mode is proposed to increase the level of security and to enhance the performance of image encryption. The modification is done by combining the GEFFE Generator with AES.
