具体实施方式Detailed ways
为了使本发明所解决的技术问题、技术方案及有益效果更加清楚明白，以下结合附图及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
图1是现有技术无线升级手机软件的方法流程图，该无线升级方法包括以下步骤：Fig. 1 is the method flowchart of prior art wireless upgrading mobile phone software, and this wireless upgrading method comprises the following steps:
1、从服务器下载软件升级包，设置进入恢复模式的重启原因和升级标志。所述软件升级包是比较新版本的系统镜像文件和手机系统当前版本的系统镜像文件得到的差分包。所述设置进入恢复模式的重启原因和升级标志具体是指将一个进入恢复模式的重启原因和升级标志写入寄存器。所述恢复模式即手机软件升级时进入的模式。1. Download the software upgrade package from the server, and set the restart reason and upgrade flag for entering recovery mode. The software upgrade package is a differential package obtained by comparing the system image file of the new version with the system image file of the current version of the mobile phone system. The setting of the restart reason and upgrade flag for entering the recovery mode specifically refers to writing a restart reason and upgrade flag for entering the recovery mode into a register. The recovery mode is the mode entered when the mobile phone software is upgraded.
2、启动固件引导程序 (Bootrom)加载并校验受信镜像模块(TIM：Trusted Image Module)中原始设备引导加载模块(OBM：OEM Boot-loader Module)中的校验值，如果校验成功，则加载并运行原始设备引导加载模块。手机中的受信镜像模块中存储有原始设备引导加载模块的校验值，引导加载程序 (BLOB) 的校验值以及内核(kernel)的校验值，用来校验相关的原始设备引导加载模块、引导加载程序及内核三个部分的数据是否有被破坏或者是未经加密签名的文件。原始设备引导加载模块在出厂之后默认是固定不让修改的，故此步骤中校验受信镜像模块中原始设备引导加载模块的校验值在最开始没被升级破坏的情况下一般可以通过。但是一旦校验原始设备引导加载模块的校验值不能通过就无法启动原始设备引导加载模块，由于手机的烧录软件信息就存储在原始设备引导加载模块中，这样手机就不能通过重新烧录手机软件信息来恢复使用，导致手机完全无法使用。2. Start the firmware boot program (Bootrom) to load and verify the verification value in the original device bootloader module (OBM: OEM Boot-loader Module) in the trusted image module (TIM: Trusted Image Module). If the verification is successful, then Load and run the raw device bootloader module. The trusted image module in the mobile phone stores the check value of the original device boot loader module, the check value of the boot loader (BLOB) and the check value of the kernel (kernel), which are used to verify the related original device boot loader module Check whether the data in the three parts of , bootloader and kernel are damaged or not encrypted and signed. The original device bootloader module is fixed by default and cannot be modified after leaving the factory. Therefore, in this step, the verification value of the original device bootloader module in the trusted image module can generally pass if it is not damaged by the upgrade at the beginning. However, once the verification value of the original device bootloading module fails to pass, the original device bootloading module cannot be started. Since the burning software information of the mobile phone is stored in the original device bootloading module, the mobile phone cannot be reprogrammed. Software information to restore the use, making the phone completely unusable.
3、启动原始设备引导加载模块加载并校验受信镜像模块中引导加载程序的校验值。 3. Start the boot loader module of the original device to load and verify the check value of the boot loader in the trusted image module. the
4、校验引导加载程序的校验值是否成功。校验不成功，因为原始设备引导加载模块已经启动，我们可以通过重新烧录软件信息的方式恢复手机使用，如果校验成功，则加载并运行引导加载程序。4. Verify whether the verification value of the bootloader is successful. The verification is unsuccessful because the bootloader module of the original device has been activated. We can restore the phone to use by re-burning the software information. If the verification is successful, load and run the bootloader.
5、启动引导加载程序检查是否有升级标志。5. Start the bootloader to check if there is an upgrade flag.
如果重启原因不是设置的升级标志，则加载正常模式的内核，并正常启动。所述正常模式即手机正常启动的模式。If the reason for the restart is not the set upgrade flag, load the kernel in normal mode and start normally. The normal mode is a mode in which the mobile phone starts up normally.
如果重启原因是定义好的升级标志的话，手机进入一个专门的升级模式，也就是恢复模式，加载并把控制权交给内核。加载并运行恢复模式的内核，挂载受信镜像模块。If the restart reason is a well-defined upgrade flag, the phone enters a special upgrade mode, that is, the recovery mode, loads and hands over control to the kernel. Load and run the recovery mode kernel, mount the trusted image module.
6、启动固件无线更新升级工具开始运行升级过程，并更新受信镜像模块。在固件无线更新升级工具开始运行升级过程中更改引导加载程序和内核，相应地，更新受信镜像模块中储存的引导加载程序的校验值以及内核的校验值，在更新更新受信镜像模块的过程若出现手机没电等中断升级的意外情况，受信镜像模块中的校验值就会出现错误，而受信镜像模块中包括原始设备引导加载模块的校验值、引导加载程序的校验值以及内核的校验值，虽然更新的只是引导加载程序的校验值以及内核的校验值，但是只要引导加载程序的校验值以及内核的校验值任何一个出现错误都会导致整个受信镜像模块不能打开，从而在下次进行升级过程中上述步骤2中：校验受信镜像模块中原始设备引导加载模块的校验值这一步骤不能通过，那么就无法加载运行原始设备引导加载模块，由于手机的烧录软件信息就存储在原始设备引导加载模块中，因此不能通过重新烧录手机软件信息来恢复使用。6. Start the firmware wireless update and upgrade tool to start the upgrade process and update the trusted image module. When the firmware wireless update and upgrade tool starts to run and upgrade, the boot loader and kernel are changed. Correspondingly, the check value of the boot loader and the check value of the kernel stored in the trusted image module are updated. In the process of updating the trusted image module If there is an unexpected situation where the upgrade is interrupted, such as the mobile phone is out of power, the check value in the trusted image module will be wrong, and the trusted image module includes the check value of the original device boot loader module, the check value of the boot loader, and the kernel. Check value, although only the check value of the boot loader and the check value of the kernel are updated, but as long as any error occurs in the check value of the boot loader and the check value of the kernel, the entire trusted image module cannot be opened. , so that in the next upgrade process in the above step 2: the step of verifying the verification value of the original device bootloader module in the trusted image module cannot pass, then the original device bootloader module cannot be loaded and run, due to the burning of the mobile phone The software information is stored in the original device bootloader module, so it cannot be recovered by reflashing the mobile phone software information.
7、启动固件无线更新升级工具清除升级标志。7. Start the firmware wireless update tool to clear the upgrade sign.
8、升级标志清除后重新启动手机。8. Restart the phone after the upgrade sign is cleared.
从上述现有的无线升级手机软件的方法中我们可以知道，现有的无线升级手机软件的方法若在升级受信镜像模块过程中出现手机突然断电等中断升级的意外事件将会导致手机无法再使用，没有安全保障。We can know from above-mentioned existing method for wirelessly upgrading mobile phone software, if in the existing method for wirelessly upgrading mobile phone software, unexpected events such as sudden power failure of the mobile phone occur in the process of upgrading the trusted image module, the mobile phone will no longer be able to use, there is no security guarantee.
为克服上述技术问题，本发明实施例提供一种安全的无线升级手机软件的方法。如图2所示，是本发明实施例提供的无线升级手机软件的方法流程图，该无线升级方法包括以下步骤：In order to overcome the above-mentioned technical problems, an embodiment of the present invention provides a safe wireless method for upgrading mobile phone software.

Download a software upgrade package from the server, and set a restart reason and an upgrade flag for entering the recovery mode. The software upgrade package is a differential package obtained by comparing the system image file of the new version with the system image file of the current version of the mobile phone system. The setting of the restart reason and upgrade flag for entering the recovery mode specifically refers to writing a restart reason and upgrade flag for entering the recovery mode into a register. The recovery mode is the mode entered when the mobile phone software is upgraded.
S2、启动固件引导程序加载并校验受信镜像模块中原始设备引导加载模块的校验值，并加载运行原始设备引导加载模块。本实施例中的受信镜像模块中存储有原始设备引导加载模块校验值，用来校验原始设备引导加载模块的数据是否有被破坏或者是未经加密签名的文件。原始设备引导加载模块在出厂之后默认是固定不让修改的，故此步骤中校验受信镜像模块中原始设备引导加载模块的校验值一般可以通过。如果校验成功，则加载并运行原始设备引导加载模块。S2. Start the firmware bootloader to load and verify the check value of the original device bootloader module in the trusted image module, and load and run the original device bootloader module. The trusted image module in this embodiment stores a check value of the original device bootloader module, which is used to check whether the data of the original device bootloader module is damaged or is a file that has not been encrypted and signed. The original device bootloader module is fixed by default and cannot be modified after leaving the factory, so the verification value of the original device bootloader module in the trusted mirror module can generally be verified in this step. If the verification is successful, the raw device bootloader module is loaded and run.
S3、启动原始设备引导加载模块加载并校验备份受信镜像模块(DTIM： Double Trusted Image Module)中引导加载程序的校验值。本实施例中的备份受信镜像模块中存储有引导加载程序的校验值以及内核的校验值，用来校验引导加载程序和内核两个部分数据是否有被破坏或者是未经加密签名的文件。S3. Start the original device boot loader module to load and verify the check value of the boot loader in the backup trusted image module (DTIM: Double Trusted Image Module). The backup trusted image module in this embodiment stores the check value of the boot loader and the check value of the kernel, which are used to check whether the two parts of the data of the boot loader and the kernel are damaged or unencrypted. document.
S4、校验引导加载程序的校验值是否成功。校验不成功，因为原始设备引导加载模块已经启动，我们可以通过重新烧录软件信息的方式恢复手机使用，如果校验成功，则加载并运行引导加载程序。S4. Verify whether the verification value of the boot loader is successful. The verification is unsuccessful because the bootloader module of the original device has been activated. We can restore the phone to use by re-burning the software information. If the verification is successful, load and run the bootloader.
S5、启动引导加载程序检查是否有升级标志。如果重启原因不是定义的升级标志，则加载正常模式的内核，并正常启动。所述正常模式即手机正常启动的模式。如果重启原因是定义好的升级标志的话，手机进入一个专门的升级模式，也就是恢复模式，加载并运行恢复模式的内核，挂载备份受信镜像模块。S5. Start the boot loader to check whether there is an upgrade flag. If the reboot reason is not one of the defined upgrade flags, a normal-mode kernel is loaded and booted normally. The normal mode is a mode in which the mobile phone starts up normally. If the restart reason is a defined upgrade flag, the mobile phone enters a special upgrade mode, that is, the recovery mode, loads and runs the recovery mode kernel, and mounts the backup trusted image module.
S6、启动固件无线更新升级工具开始运行升级过程，并更新备份受信镜像模块。在固件无线更新升级工具开始运行升级过程中更改引导加载程序和内核，相应地，更新备份受信镜像模块中储存的引导加载程序的校验值以及内核的校验值，在更新更新受信镜像模块的过程若出现手机没电等中断升级的意外情况，只有备份受信镜像模块的校验值出现错误，从而破坏掉备份受信镜像模块，但是因为受信镜像模块没有被更改和破坏，因此可以通过重新烧录手机软件信息来恢复使用。而受信镜像模块中只包括原始设备引导加载模块的校验值，在软件进行升级的过程中并没有被更改，所以在下次进行升级过程中上述步骤S2中：校验受信镜像模块中原始设备引导加载模块的校验值这一步骤一直可以通过，由于手机的烧录软件信息就存储在原始设备引导加载模块中，因此就算在升级过程中出现中断升级的意外情况也可以通过重新烧录手机软件信息来恢复手机的使用。S6. Start the firmware wireless update and upgrade tool to run the upgrade process, and update the backup trusted image module. Change the boot loader and kernel when the firmware wireless update upgrade tool starts to run the upgrade process. Correspondingly, update the check value of the boot loader and the check value of the kernel stored in the backup trusted image module. If there is an accident in the upgrade process, such as the mobile phone running out of power, only the verification value of the backup trusted image module will be wrong, thus destroying the backup trusted image module. However, because the trusted image module has not been changed or destroyed, it can be reprogrammed Mobile phone software information to resume use. The trusted image module only includes the verification value of the original device bootloader module, which has not been changed during the software upgrade process, so in the above step S2 in the next upgrade process: verify the original device bootloader in the trusted image module The step of loading the verification value of the module can always be passed. Since the burning software information of the mobile phone is stored in the original device bootloading module, even if there is an unexpected interruption of the upgrade during the upgrade process, it can be re-burned through the mobile phone software. information to restore the use of the phone.
S7、启动固件无线更新升级工具清除升级标志。S7. Start the firmware wireless update upgrade tool to clear the upgrade mark.
