Image encryption based on new Beta chaotic maps

•Creation of new chaotic maps based on Beta function.•Application of the new created chaotic maps on image encryption process.•Tests for the new maps performances based on various types of differential and statistical analyses.•Comparison between our experimental results and other previous maps and algorithms results.

In this paper, we created new chaotic maps based on Beta function. The use of these maps is to generate chaotic sequences. Those sequences were used in the encryption scheme. The proposed process is divided into three stages: Permutation, Diffusion and Substitution. The generation of different pseudo random sequences was carried out to shuffle the position of the image pixels and to confuse the relationship between the encrypted the original image, so that significantly increasing the resistance to attacks. The acquired results of the different types of analysis indicate that the proposed method has high sensitivity and security compared to previous schemes.
