A New Duffing-Lorenz Chaotic Algorithm and Its Application in Image Encryption

Abstract

The Duffing and Lorenz chaotic algorithm proposed of today are too simple in structure and have inadequate parameters, so that they are not suitable for the encryption in cryptography. By mixing the Duffing chaotic algorithm with the Lorenz chaotic algorithm, a new six-dimensional chaotic cryptographic algorithm with a more complex structure is proposed. The Lyapunov exponent simulation shows that the new chaotic algorithm has strong chaotic features. It can be used in the image encryption after undergoing a newly designed dynamic mapping.
