Embodiment Construction

[0072]The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0073] An embodiment of the present application provides an unlocking method, which is applied to an electronic device, specifically, such as figure 1 As shown, the unlocking method provided in this embodiment of the application may include:

[0074] S101, run the kernel bootloader after starting up and powering on.

[0075] After the electronic device is turned on and powered on, it enters the kernel boot stage, and runs the kernel boot program in the kernel boot stage. The kernel...

Abstract

The invention provides an unlocking method and device. The method comprises the steps: initializing equipment hardware related to an unlocking operation in a process of running a kernel boot program, and executing the unlocking operation based on the initialized equipment hardware to obtain an unlocking result, only when the unlocking result shows that unlocking succeeds, the kernel bootstrap program can continue to run and the operating system is started, namely normal starting is achieved, and otherwise starting cannot be achieved. The startup unlocking operation is completed in the kernel guiding stage, and the operation system of the electronic equipment is not started and operated in the kernel guiding stage, so that the situation that the root permission is obtained by an illegal user is avoided, and the safety of the electronic equipment is improved.

Description

technical field [0001] The invention belongs to the technical field of electronic equipment, and in particular relates to an unlocking method and device. Background technique [0002] Important information is stored in electronic devices, and once lost, the important information will be leaked. In order to improve the security of the electronic device, an unlocking operation is provided before starting the device. Only after the unlocking is successful, the device can be started normally; otherwise, the electronic device cannot be started normally, and important information in the electronic device cannot be obtained. [0003] In the method of power-on unlocking provided in the prior art, after the electronic device is started, the power-on unlocking operation needs to be performed only after the electronic device runs to the power-on interface. In this case, the operating system of the electronic device is already in the running state, resulting in the use of many function...
