Ayten Mazen, Yousef Korayem, Mohamed Gabr, Wassim Alexan · 2023
The effectiveness of image encryption is increasing every day due to the increased demand for online images and concerns about their privacy. In this paper, a 3-stage image encryption algorithm is proposed. This paper utilizes a new 7D hyperchaotic function in the first stage. Then, an extended cellular automaton S-box is used in the second stage. Finally, cellular automata is used as the third layer. The proposed encryption technique exhibits high resistance to a variety of attacks while consuming little computational resources, making it suitable for real-time applications.
