With the development and application of network technology, digital images, as a form of information transmission, are at high risk of being stolen or decrypted. Our scheme utilizes the nature of low dimensional chaos to generate a high dimensional chaotic system with more variables and higher complexity by mixing two different low dimensional chaotic systems to protect digital images and confirms that it outperforms the original system through simulation experiments. In this paper, a new image scrambling encryption algorithm for multi chaotic system is designed by combining improved tent mapping and high-dimensional chaotic system, and compared with the existing encryption scheme in terms of simulation experiments and security performance parameters, which proves that the scheme has better comprehensive ability.
