Problems solved by technology

In this way, once the loaded Kernel file and System file have problems (for example, there are malicious codes, large loopholes, etc.), it is easy to bring a relatively large security risk, which not only affects the use of users, but also may cause user losses.

Abstract

The invention discloses a method and device for processing an operating system file. The method applied to a server includes the steps that an original operating-system kernel file is processed according to a first preset rule to generate a first check word, and an original system file is processed according to a second preset rule to generate a second check word; first header information and second header information are generated, a first preset position of the first header information is filled with the first check word, and a second preset position of the second header information is filled with the second check word; the first header information is added to the head of the original operating-system kernel file to form a target operating-system kernel file, and the second header information is added to the head of the original system file to form a target system file, wherein the target operating-system kernel file and the target system file are used for being loaded by a terminal. In this way, an unlawful operating system can be effectively prevented from being installed on the terminal, the safety of an operating system of the terminal can be improved, and a user is prevented from suffering from losses.

Description

technical field [0001] The present invention relates to the field of operating systems, in particular to a method and device for processing operating system files. Background technique [0002] Currently, many terminal service providers provide users with third-party ROMs, that is, operating systems of terminals. In this way, when the user's terminal needs to be reset due to a system failure, or when the user prefers the system configuration of a third-party ROM, the user's terminal can download the operating system files (including the operating system kernel ( Kernel) files and system (System) files), and then replace the operating system currently used by the terminal with this operating system to complete the "flash" operation. However, in the existing "refreshing" process, after the terminal loads the Kernel file and the System file, it will directly execute the Kernel file and the System file, that is, directly run the loaded operating system from a third party on the...
