Description
Summary:In view of the shortcomings of existing chaotic image encryption algorithms, such as low encryption efficiency and inability to resist chosen plaintext attack, this paper proposes an image encryption algorithm based on hyper chaotic system with spiral scrambling. Firstly, the initial scrambling point is selected according to the plaintext image, and then the pseudo random sequence is generated by hyper chaotic system, and then the plaintext associated pixel diffusion is carried out. Experimental results and simulation analysis show that the algorithm has high efficiency and good security, and thus has good application scenarios.
