Medical images contain sensitive information and are prone to various attacks during network transmission. Therefore, it is essential to develop a robust algorithm to ensure the safety of transmitting medical images. In this paper, we propose an efficient and secure color medical image encryption system utilizing the FRFT-DRPE optical transformation and 2D-SICM hyperchaos system. The encryption process in our system considers the specific characteristics of each channel in the HSI color model. First, the image is converted from RGB space to HSI space. Subsequently, different encryption methods are applied to the hue and saturation components, including S-box replacement, scrambling, and diffusion operations. For the intensity component, scrambling and FRFT-DRPE optical encryption operations are performed. Additionally, the order of 2D-FRFT serves as an additional key to enhance the security of the encryption system. Finally, the three channels are merged to complete the overall encryption process. Simulations and performance analysis have confirmed the high-security level of our algorithm. It effectively protects the privacy of medical images during transmission. [ABSTRACT FROM AUTHOR] |
