Control systems and methods for securely loading software in a power control system. In some examples, the control system includes a computing device and a plurality of security modules. The computing device may obtain and divide an executable image into a plurality of images. The computing device may generate a control hash as a function of the plurality of images, and record the control hash. The computing device may store each of the plurality of images in a plurality of security modules. At boot up, the computing device may load, from each security module, the stored image, and store each image to a memory device. The computing device may generate a hash based on the stored images, and compare the generated hash to the recorded control hash. Based on the comparison, the computing device may allow execution of the executable image.
