“…Jeong et al designed an encryption algorithm for medical color image using the map modified (5) [8]. However, (5) only changes the pixel position of the gray image because it can change the pixel position of the two-dimensional image.…”

“…To create a key image, we need two CoCAs consisting of a nonlinear CA and a 90/150 MLCA. In 8-cell CA, the number of rules is the number of cases applicable to each cell, which is 2 8 . the number of rules that can be used for two CoCAs is 2 8×16 • 2 8×16 = 2 256 .…”

“…Recently, methods of medical image encryption based on chaotic function have been studied by many researchers [2][3][4][5][6][7][8][9][10]. Mao et al proposed a cryptographic algorithm that not only maintains a high level of security but also speeds up image encryption using a map that extends the Baker map in three dimensions [2].…”

“…And then they changed pixel positions of the image with pixel value changed using the modified chaotic map. However, the modified chaotic maps they designed have an unmaintained weakness of the image size required by the chaotic cat map [8]. Therefore, there is a need to overcome the weaknesses of the modified two-dimensional chaos function in [8] and to efficiently encrypt color images.…”

Medical images are transmitted via the Internet or the hospital intranet which include many important information about the patient's personal information. Medical image encryption is a technology that can effectively protect the information contained in these medical images. In this paper, we give a secure and trusty Combined Cellular Automata (CoCA) based medical image encryption algorithm. CoCA is made up of a nonlinear CA and a linear 90/150 maximum length CA, and three dimensional generalized chaotic map. The proposed algorithm consists of two phases. The first phase encryption process that changes pixel values of a given image using two CoCAs. The second phase is to change the position of each pixel in the image encrypted using the three dimensional generalized chaotic cat map that can change with effect the position of pixels not only in two dimensions horizontally and vertically but also in color plane three colored channels simultaneously. We show the stability and high reliability of the given color medical image cryptosystem through detailed analysis and various statistical experimental tests.
