Abstract

Discloses are a software control method and device and a mobile terminal. The method includes the steps of obtaining a first operation instruction input by a user; when the first operation instruction is a software extraction instruction, outputting encrypted first system software, wherein the first system software is obtained by encrypting an identification of the mobile terminal with second system software the protection mechanism of which is invalid, when the second system software is loaded to the mobile terminal. According to the software control method and device and the mobile terminal, the system software extracted by illegal users from the mobile terminal is the encrypted first system software, when the encrypted first system software is loaded into other mobile terminals, since the other mobile terminals lack a secret key to decrypt the first system software, the second system software can not be used on the other mobile terminals, and therefore loopholes of the second system software can not be utilized to install other unauthorized software as the system software of the mobile terminal. The software control method and device and the mobile terminal reduce profit loss of mobile terminal manufacturers, when the system software serves as a basic approach to earning profit.

Description

Technical field [0001] This openness involves communication technology, especially for software control methods, devices and mobile terminals. Background technique [0002] With the continuous progress of communication technology, mobile terminals such as mobile phones and tablets have become indispensable tools in people's lives. People can chat, shop, book tickets, etc. through mobile phones and tablets, which greatly facilitates people's lives. [0003] Taking mobile phones as an example, under the rapid development of the current Internet model, the income of more and more mobile phone manufacturers comes from the system software built -in mobile phones developed in the mobile phone, which makes corresponding profits through the user's use. In related technologies, mobile phone manufacturers built-in mobile phone system software through the corresponding protection mechanism, such as a set of Verifiedboot and DM-Verity defined by Google to ensure that the data of the bottom K...
