Based on the Adomian decomposition method and Lyapunov stability theory, this paper constructs a fractional-order\nmemristive hyperchaos. Then, the 0â??1 test analysis is applied to detect random nature of chaotic sequences exhibited by the\nfractional-order systems. Comparing with the corresponding integer-order hyperchaotic system, the fractional-order\nhyperchaos possesses higher complexity. Finally, an image encryption algorithm is proposed based on the fractional-order\nmemristive hyperchaos. Security and performance analysis indicates that the proposed chaos-based image encryption algorithm\nis highly resistant to statistical attacks.
