Example Embodiment

[0023] The Android system protection method and device of this embodiment judges whether the recovery image file in the recovery partition is modified, and if it is modified, the backup file of the recovery image file is upgraded to the recovery partition to avoid the device from flashing the third-party recovery image After the file is upgraded, the system is upgraded through OTA, which improves the security of the system.

[0024] In order to make the objectives, technical solutions and advantages of the present invention clearer, the following will further describe the present invention in detail with reference to the accompanying drawings and embodiments.

[0025] The Android system protection method of this embodiment specifically includes the following steps.

[0026] Start the bootloader (boot boot program), and detect that the mobile terminal triggers the operation to enter the recovery mode. There are many trigger operations that trigger the mobile terminal to enter the rec...

Abstract

The invention discloses an Android system protection method and apparatus. The protection method comprises the following steps of: acquiring a backup file of a recovery image file, wherein the backup file of the recovery image file comprises a recovery image file generated in the compiling process of an Android system, and a hash value and a file size of the recovery image file; judging whether the current recovery image file of the system is modified; and if yes, upgrading the backup file of the recovery image file to a recovery partition. According to the Android system protection method and apparatus which are disclosed by the invention, a device is avoided being rooted by an OTA (Over-the-Air Technology) upgrade package after a third party recovery image file is flashed into the device; the condition that due to a user roots the device, the device cannot be normally used and even is bricked is prevented; safety of the device is improved; and normal use of the user and benefits of manufacturers are ensured.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an Android system protection method and device. Background technique [0002] OTA upgrade is a commonly used terminal firmware upgrade method. Users can upgrade the terminal system firmware through OTA upgrade. [0003] In order to increase the security of the OTA upgrade and prevent the third-party OTA upgrade package from being flashed to the Android terminal, the public key file will be loaded from the recovery image file before the OTA upgrade, and the signature information embedded in the OTA upgrade package will be verified with the public key file. If it is correct, the upgrade will be performed only after the verification is successful, and the upgrade operation will not be performed if the verification fails. [0004] However, this mechanism is not very safe, because if the user flashes his terminal into a third-party recovery image file in some way, the correspo...
