Recent times have seen a massive rise in the transmission and storage of DICOM images. This work proposes a cryptosystem with the sturdy JSMP map, for the pixel data of the DICOM file. The proposed system is designed to work in the bit plane level for high resilience. To achieve an effective cryptosystem, the number of bit planes generated depends on the bits stored attribute and not on the conventional method of bits allocated of each pixel. Only the MSB bit planes that contribute more to the details of the image are shuffled with the JSMP chaotic keys. Then the shuffled image is reconstructed by combining all the MSB and LSB bit planes. Finally, a robust cipher image is generated by diffusing the reconstructed image with a random image generated with JSMP map. The novelty and uniqueness of the system lie in its capability of encrypting DICOM images with any pixel depth. The distinctive feature of this system is the unique key generation algorithm and the variable number of keys, which contributes to high sensitivity and entropy. Performance measures of the encrypted image illustrate the robustness of the cryptosystem in the health information system.

最近，DICOM 图像的传输和存储出现了大幅增长。这项工作为 DICOM 文件的像素数据提出了一个具有坚固 JSMP 映射的密码系统。所提出的系统被设计为在位平面级别工作以实现高弹性。为了实现有效的密码系统，生成的位平面的数量取决于位存储属性，而不取决于为每个像素分配位的传统方法。只有对图像细节贡献更大的 MSB 位平面才使用 JSMP 混沌键进行混洗。然后通过组合所有 MSB 和 LSB 位平面来重建混洗后的图像。最后，通过用 JSMP 映射生成的随机图像对重构图像进行扩散，生成鲁棒的密码图像。该系统的新颖性和独特性在于它能够加密任何像素深度的 DICOM 图像。该系统的显着特点是独特的密钥生成算法和可变数量的密钥，这有助于实现高灵敏度和熵。加密图像的性能测量说明了健康信息系统中密码系统的鲁棒性。
