The application of image encryption method based on chaotic mapping in the field of radar transmitter remote monitor system

Because keeping technical secrets are essential when it comes to radar technology, the parameters and images captured from the equipment should be transmitted in a safe channel. The security of image data must be taken into account. In this paper, a new image encryption method based on chaos map is proposed, which is the permutation and diffusion framework. In the replacement of this step, according to the permutation matrix with the generation of the original image and the original image of the same size, use the matrix to completely disrupted of original image pixel location so as to reduce the correlation between neighboring pixels. And with the help of S-box, use continuously updated encryption coefficients are encrypted. The results of the simulation show that the image encryption scheme has high security and efficiency.
