A random S-box is designed by using the mixed linear-nonlinear spatiotemporal chaotic system. Firstly, a chaotic sequence produced by the mixed chaotic system is used to generate the elements of the S-box randomly. Then the elements of the S-box are permuted by using the mixed chaotic system. Owing to the high dimensional feature of the mixed chaotic system, the generated S-box has a strong randomness property. Finally, we analyse six properties of the designed S-box, such as bijective property, nonlinearity, strict avalanche criterion, outputs bit independence criterion, input/output XOR distribution and linear approximation probability. The experimental results indicate that the designed S-box by using the mixed chaotic system has better performance.
