Problems solved by technology

However, modifying the system partition file will cause great damage to the mobile device. Taking the mobile phone as an example, if some files in the system partition of the mobile phone are deleted, it is likely to cause the OTA upgrade of the mobile phone to fail, and even cause the mobile phone to become a brick and cannot be turned on.

Abstract

The invention relates to an access control method and device, and related equipment, wherein the access control method is applied in an Android system. The method comprises following steps of receiving a request for reloading a system subarea as a read-write state, wherein parameters which are input by a requester and are used for obtaining the read-write privileges of the system subarea are carried in the request; detecting whether the parameters which are input by a requester and are used for obtaining the read-write privileges of the system subarea in the request are consistent with special parameters prebuilt in a recovery mode program or not; and processing the request according to a detection result. According to the method, the device and the equipment, through limiting the read-write privileges of the file system of the mobile equipment, the damage possibly brought to the original system subarea file of the mobile equipment is indirectly limited, therefore, the security of the system subarea file of the mobile equipment is improved, and an OTA (Over-the-Air Technology) update failure resulting from the damage of the system subarea file can be avoided.

Description

technical field [0001] The present invention relates to the communication field, in particular to an access control method, device and related equipment. Background technique [0002] At present, smart mobile devices have been widely used. The operating system is an important part of a smart mobile device. Among them, Linux is a set of Unix-like operating systems that are free to use and spread freely. It is a multi-user, multi-tasking, multi-threading and multi-CPU operating system based on POSIX and UNIX. Linux can run major UNIX utility software, application programs and network protocols. Linux supports both 32-bit and 64-bit hardware. Linux inherits Unix's network-centric design idea and is a multi-user network operating system with stable performance. Linux is mostly used in the embedded operating system of mobile phones. [0003] The terms related to mobile devices are explained below. [0004] For the Android (Android) operating system, the System partition (al...
