Abstract  In order to make the chaotic sequence show more complex characteristics, a piecewise linear function is introduced into the typical Chua’s system to produce a controllable number of multi-scroll attractors. The dynamic analysis of this system is performed, and the results illustrate that the chaotic characteristics of the system are widely distributed and have rich dynamic behaviors. On this basis, an encryption algorithm based on Zigzag scrambling and DNA coding is proposed, and its security is analyzed from multiple aspects. The simulation results indicate that this method can not only encrypt the image effectively, but also resist a variety of common attacks effectively, which provides a theoretical basis for image encryption.
