In this paper, a novel image encryption tool based on chaotic automorphism and the Chirikov transform is proposed. The lack of efficiency of the chaotic automorphism, such as ghost and miniature effects, is overcome with the help of the Chirikov transformation. Normalized pixel change rate, correlation coefficient, and histogram analysis are employed in order to validate the efficiency of the proposed method. According to the results, the proposed algorithm demonstrates its robustness against attacks based on statistical analysis. © 2024, International Scientific Research Publications.
