Problems solved by technology

[0009] Fourth, dependencies on server systems can be restricted so that the use of computing bases critical to security can be curtailed
For example: Different processors and development boards usually provide real-time clock support to get the current time and date, but there are countless ways to implement real-time clocks

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...

Abstract

The invention particularly relates to a high-security micro-kernel startup mode. The high-security micro-kernel startup mode comprises: judging whether a root task exists or not first after starting a kernel; if the root task exists, starting the root task, wherein the root task has a full right to process all resources; and if the root task does not exist, exiting kernel operation, thereby ending kernel startup. According to the high-security micro-kernel startup mode, other tasks are set by the root task once the kernel is started, and the other tasks are granted rights to construct a complete system, so that the micro-kernel startup is more secure and effective.

Description

technical field [0001] The invention relates to the technical field of computer microkernel, in particular to a high-safety startup mode of the microkernel. Background technique [0002] Microkernel (Microkernel) is a simplified version of the kernel that provides the core functions of the operating system. It is designed to increase portability in a small memory space and provides a modular design to allow users to install different interfaces. Therefore, it can also be said that the microkernel is the smallest core of an operating system (OS). New operating systems from IBM, Microsoft, the Open Software Foundation (OSF), and UNIX Systems Laboratories (USL) have all taken advantage of this research. [0003] It presents a very small subset of what is generally considered an operating system today. The definition of a microkernel is given by Litke: A concept is tolerable in a microkernel only if moving it outside the kernel, e.g., to allow competing implementations, would ...
