Embodiment Construction
[0024] The accompanying drawings are a specific embodiment of the present invention, and the present invention will be described in detail below in conjunction with the accompanying drawings.
[0025] The startup mode of the high-security microkernel, after the kernel is started, first judges whether there is a root task, if there is a root task, then starts the root task, the root task has full authority to process all resources, and if there is no root task, then exits the kernel Run, the kernel boot ends.
[0026] The root task has full authority to handle all resources including physical memory, x86 IO ports and interrupts.
[0027] The root task sets up other tasks and grants access rights to other tasks to build a complete system.
[0028] Said access rights are granted by capability, with unforgeable tokens representing privileges that are fully delegateable.
[0029] When the root task sets other tasks, the microkernel can execute other tasks; when the root task does...
