dc.description.abstractA new RGB color image encryption algorithm is presented in this paper. The hyperchaotic two-dimensional logistic-sine-coupling map (2D-LSCM), which was previously suggested in the literature, is used in this study to generate the necessary parameters for the cross-channel pixel and bit scrambling, and the diffusion stages. The SHA-512 hash value of the plain color image is used to calculate the initial values of the map. In the pixel-level scrambling stage, a novel cross-channel scrambling method is implemented. The pixels in each channel are transformed by exchanging rows and columns between different channels according to the random sequences generated by 2D-LSCM. The four most significant bits of each channel's pixels are concatenated and circularly shifted horizontally and vertically in the cross-channel bit scrambling stage. Finally, in the diffusion stage, each channel's scrambled pixels are diffused using the diffusion sequences that are controlled by the control sequences. To assess the security performance of the presented method, several analyses such as key sensitivity analysis, statistical analysis, information entropy analysis, differential attack analysis, and noise & data loss analysis are performed. The experimental analyses and comparisons with other methods show that the proposed method can be used to efficiently encrypt color images.en_US
