Recently, the transport massive and secure data are fateful and difficult in communication over the IoT. Due to their widespread use and ease of transmission, images are the most frequent and well-liked multimedia data format. Among the various cryptography methods, chaos-based image cryptography is regarded as the one that is best suitable for picture applications due to its sensitivity to the beginning circumstances and control parameters. Conventional image cryptography techniques have employed confusion and diffusion techniques, but the perfect encrypted image has not yet been produced. Secure image transmission is the main goals in proposed method. Therefore, the new chaos method based on confusion and diffusion method is introduced to secure the image transmission. Generally, the confusion technique is used to produce random numbers for the pixel permutation method. While the random matrix is produced using the diffusion approach. The main idea of the proposed method is to idealize the histogram and information entropy of the ciphered image. The experimental results demonstrated that comparing the suggested strategy to benchmark methods stimulates better results. The experimental result showed that the test of the proposed method encourages outcomes against benchmarked methods.
