More Information
Summary: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. 本发明提供一种解锁方法及装置，该方法在运行内核引导程序的过程中，对与解锁操作相关的设备硬件进行初始化，并基于初始化后的设备硬件执行解锁操作，得到解锁结果，只有解锁结果表示解锁成功时才能继续运行内核引导程序并启动操作系统，即正常开机，否则不能开机。由于在内核引导阶段完成了开机解锁操作，而在内核引导阶段电子设备
