Cartoon Image Encryption Algorithm by a Fractional-Order Memristive Hyperchaos

الملخص EN

Based on the Adomian decomposition method and Lyapunov stability theory, this paper constructs a fractional-order memristive hyperchaos.

Then, the 0–1 test analysis is applied to detect random nature of chaotic sequences exhibited by the fractional-order systems.

Comparing with the corresponding integer-order hyperchaotic system, the fractional-order hyperchaos possesses higher complexity.

Finally, an image encryption algorithm is proposed based on the fractional-order memristive hyperchaos.

Security and performance analysis indicates that the proposed chaos-based image encryption algorithm is highly resistant to statistical attacks.
