In the process of encryption algorithm scrambling and diffusion, data scrambling is achieved by XORing the plaintext with the output (chaotic pseudo-random sequence) of the Lorenz chaotic system. Meanwhile, data diffusion is achieved by XORing the result of XORing the plaintext with the output of the Lorenz chaotic system with the previously encrypted medical image data. The process of scrambling and diffusion alternates continuously. However, this encryption process suffers from the problem of high vertical correlation coefficient of the encrypted ciphertext. Although significant reduction has been achieved by improving the ImproLorenz chaotic system, the problem still requires further research.
To address these limitations, researchers have proposed various modifications and extensions to the Lorenz chaotic system, such as introducing additional variables or changing system parameters. These methods aim to enhance the predictability and applicability of the system, but they also introduce new challenges and complexities that require careful consideration and analysis. This research is crucial to ensure the security and reliability of medical image encryption
