A substitution box (S‐box) plays a central role in cryptographic algorithms. In this paper, an efficient method for designing S‐boxes based on chaotic maps is proposed. The proposed method is based on the mixing property of piecewise linear chaotic maps. The S‐box so constructed has very low differential and linear approximation probabilities. The proposed S‐box is more secure against differential and linear cryptanalysis compared to recently proposed chaotic S‐boxes.
