Abstract

The invention relates to a power-on control method and device. The method comprises the following steps: generating and displaying a power-on password input interface when a first power-on password isstored in a password storage chip of a terminal after the terminal is electrified; receiving a second power-on password through the power-on password input interface; sending the second power-on password to the password storage chip such that the second power-on password is verified by the password storage chip according to the first power-on password; and starting an operation system of the terminal when the second power-on password is successfully verified. With the power-on control method and device, power-on passwords are stored in the password storage chip in order to prevent the power-on passwords from being deleted or tampered after the terminal is rooted. Therefore, safety of the power-on passwords is ensured. During a power-on process, the second power-on password acquired by a controller is verified on the password storage chip, which further ensures safety of verification of the power-on passwords.

Description

technical field [0001] The invention relates to the field of computers, in particular to a boot control method and device. Background technique [0002] The power-on password of the traditional terminal is stored in the data partition. When starting up, the controller reads the power-on password stored in the data storage partition for verification to enter the operating system of the terminal. However, the power-on password of the terminal is rooted (root , is a term in the computer field. In UNIX systems, UNIX-like systems, and Android systems, the superuser is generally named root. Root is the only superuser in the system and has all permissions in the system, such as starting or stopping a process, deleting or After adding users, adding or prohibiting hardware, etc.), it can be deleted and modified, or the power-on password can also be deleted by restoring the factory settings, so that the terminal can be opened easily. [0003] On this basis, there are also many ways t...
