Abstract: An image file packaging method is applied to a first device. The first device comprises a storage device and a first processor. The image file packaging method includes: the first device receives a kernel image wherein the initial kernel header is located in the kernel image; an initial application and the kernel image are stored in the storage device; and the first processor executes a hash tree generation program. The hash tree generation program performs the following steps: calculating an initial hash tree of the initial application to obtain an initial root node, and embedding the initial root node into the initial kernel header to generate a new version kernel header.
