High dimensional hyperchaotic image encryption algorithm based on joint scrambling
In order to solve problem that image information is facing the threat of illegal theft and tampering during transmission,a high-dimensional hyperchaotic image encryption algorithm based on Arnold transform and DNA mixed coding was proposed.Firstly,several chaotic pseudo-random series were generated by an eight-dimensional sixth-order hyperchaotic system,and then the chaotic pseudo-random series and a chaotic matrix were obtained by integer processing.Then,using these chaotic pseudo-random integer series to dynamically select DNA chaotic coding rules and operation rules,the chaotic matrix and the original image matrix transformed by Arnold transformation were dynamically encoded,operated and decoded so as to realize image encryption.Finally,the algorithm was applied to image encryption,and the encryption performance was analyzed by computer simulations.The results show that the proposed encryption algorithm has excellent performance and can provide a feasible op-tion for image encryption.
