The method for upgrading the firmware of the equipment of the internet of things is used for solving the problems that when the firmware of the equipment of the internet of things is upgraded by adopting the existing firmware upgrading method, an attacker can easily acquire a complete firmware updating package, so that the updating package is replaced, and the system is tampered or damaged, so that the safety of the system is greatly influenced, and the normal operation of the equipment of the internet of things is not facilitated.
A specific implementation flow diagram of the method for upgrading the firmware of the internet of things device is shown in fig. 1, and the method mainly includes the following steps:
step 11, responding to the received firmware upgrading instruction, starting a virtual machine;
wherein, the firmware upgrading instruction carries the identifier of the firmware to be upgraded. Specifically, after the developer completes the development of the new firmware version, the new firmware version update package is uploaded to the upgrade server, and the upgrade server may generate a firmware upgrade instruction corresponding to the firmware update package, where the firmware upgrade instruction includes information such as firmware version information, an identifier (name or ID) of the firmware to be upgraded, and update on-line time, and issue the firmware upgrade instruction to each piece of internet of things equipment to be updated.
The Virtual Machine (VM) runs in a physical Machine in which firmware is installed.
the virtual machine may determine the firmware to be upgraded according to the firmware identifier carried in the firmware upgrade instruction received by the step 11, and further simulate the operating environment of the firmware to be upgraded.
In this embodiment of the application, the virtual machine may simulate an actual operating environment of the firmware to be updated by running a basic environment required by the firmware to be updated, so as to run the firmware to be updated in the virtual machine.
Specifically, the virtual machine may implement simulation of the firmware operating base environment by operating a firmware file system, a customized version system kernel on which firmware operates, specific virtual hardware on which firmware operates, and the like.
In one embodiment, the virtual machine may extract the embedded file system from the firmware image using the open source firmware extraction tool Binwalk. And extracting a file system of the device firmware from the device firmware code in the binary format by using the Binwalk component, and separating an operating system file and a user program file. The virtual machine may determine the instruction architecture and endianness of the firmware by querying the firmware Executable and Linkable Format (ELF) header. The virtual machine may determine the kernel that needs to compile the configuration by querying the library on which the firmware program depends. The virtual machine may configure the virtual hardware by querying the hardware interface called when the firmware program is running. And further simulating a basic environment required by the running of the firmware to be upgraded in the virtual machine according to the acquired information.
In addition, it should be noted that, after the virtual machine has configured all the environments required for running the firmware to be upgraded, the virtual machine may also copy the data in the physical machine and input the copied data into the virtual machine, so that the firmware to be upgraded is run in the virtual machine.
in an implementation manner, the internet of things device may download, according to the received firmware upgrade instruction, the update installation package corresponding to the firmware to be upgraded from the upgrade server, decompress the update installation package on the virtual machine configured in the execution step 12, and update the firmware to be upgraded running in the virtual machine according to the firmware update installation package.
It should be noted that, in order to ensure the security of the update installation package, before the update installation package is executed, the virtual machine may first perform security detection on the update installation package, and in an embodiment, the executing, by the virtual machine, the update installation package may include: based on the virtual machine, carrying out security detection on the update installation package; and when the safety detection is passed, the virtual machine runs the update installation package.
In this embodiment of the present application, the virtual machine may perform security detection on the downloaded update installation package according to the metadata of the firmware to be upgraded, and in this embodiment of the present application, the virtual machine may perform security detection on the update installation package according to the following method: the virtual machine acquires metadata corresponding to the firmware to be upgraded; the metadata comprises unpacking rules corresponding to the firmware to be upgraded; unpacking the update installation package according to the unpacking rule to obtain a file system corresponding to the update installation package; decompiling the file system to obtain an assembly code of the update installation package; and scanning the assembly codes of the updating installation package to perform security detection on the updating installation package.
Specifically, the virtual machine may perform security detection on the update installation package in the following manner:
the virtual machine collects metadata of current Internet of things equipment (before firmware upgrade is carried out), wherein the metadata comprises a firmware name, a firmware type, a manufacturer corresponding to the firmware, a digital signature preset by the manufacturer and unpacking rules corresponding to all the firmware, which are contained in the Internet of things equipment, and generates a firmware list of the Internet of things equipment according to the collected metadata.
After the internet of things device downloads the firmware update installation package from the upgrade server, before unpacking and updating through the virtual machine, the virtual machine first decrypts and verifies a signature of the received firmware update package, generally, in the process of packing the firmware update installation package by the upgrade server, a manufacturer encrypts the firmware update installation package and adds a digital signature corresponding to the manufacturer, so as to ensure the safety of the firmware update installation package. After the internet of things device downloads the update installation package, the virtual machine can decrypt the firmware upgrade package and perform primary security detection by executing a decryption algorithm and signature verification.
After the decryption and the preliminary security detection of the update installation package are completed, the virtual machine can acquire a firmware name corresponding to the firmware update installation package, search the firmware metadata corresponding to the current firmware update installation package in a pre-generated firmware list according to the firmware name, unpack the firmware update installation package according to unpacking rules in the searched firmware metadata to acquire a file system corresponding to the firmware update installation package, and convert machine language codes of the file system obtained by unpacking into assembly language codes in a decompiling mode. And scanning the assembly language code of the firmware update package, wherein the scanning method comprises matching the feature code, positioning a core function, extracting an associated file, and detecting and analyzing whether the bug exists in the code according to the existing bug feature library. And then determining whether the firmware update installation package has a security risk according to the scanning and detecting results.
Through the two rounds of safety detection, the virtual machine can ensure that the update installation package downloaded from the upgrade server is not tampered as far as possible, and no safety risk exists, so that the safety of subsequent simulation update upgrading on the virtual machine is ensured.
After the virtual machine passes the security verification of the update installation package in the above manner, the virtual machine can run the update installation package, and complete the update of the firmware to be updated in the virtual machine, so as to obtain the first updated firmware.
in an embodiment, in order to simulate the operating state of the first upgrade firmware in the actual generation environment through the operating state of the first upgrade firmware running in the virtual machine, in this embodiment of the application, the virtual machine may copy the service data in the actual generation environment, and run the first upgrade firmware through the service data obtained by the copying, so as to achieve an effect of simulating the operating state of the first upgrade firmware in the actual generation environment.
Specifically, the virtual machine may monitor the running state of the upgraded firmware in the following manner: copying business data generated by a production environment; and sending the service data obtained after copying to the virtual machine, so that the virtual machine performs operation test on the first upgrading firmware based on the service data, and obtains the operation state of the first upgrading firmware.
In the embodiment of the application, the virtual machine may determine whether the first upgraded firmware normally operates by determining whether an abnormal state (such as an abnormal shutdown, an abnormal restart, and other faults) occurs in the first upgraded firmware during the operation process within a preset time period (such as within 1 hour from the update and upgrade completion). When the virtual machine does not detect that the first upgrading firmware is in an abnormal state within a preset time period, determining that the first upgrading firmware is a safe firmware, and executing the step 15; and when the virtual machine detects that the first upgrade firmware is in an abnormal state within a preset time period, determining that the first upgrade firmware is an unsafe firmware, and executing step 16.
in order to avoid that the internet of things equipment cannot be normally used due to firmware update when the firmware to be upgraded on the physical machine is updated by using the update installation package, in the embodiment of the application, during the updating of the firmware on the physical machine, the upgraded firmware running on the virtual machine can be accessed into the production environment, during the updating of the firmware on the physical machine, the upgraded firmware replaces the firmware of the physical machine to execute tasks, after the firmware of the physical machine is upgraded, the firmware of the physical machine is accessed into the production environment again, and the virtual machine is closed, so that equipment resources are saved.
Specifically, the method provided by the embodiment of the present application may include: in a production environment, switching the firmware to be upgraded into a first upgraded firmware running on the virtual machine; upgrading the firmware to be upgraded in the physical machine through the updating installation package corresponding to the firmware to be upgraded to obtain second upgraded firmware; and after the firmware to be upgraded in the physical machine is upgraded, switching the first upgraded firmware running on the virtual machine to the second upgraded firmware in the physical machine in a production environment, and closing the virtual machine.
And step 16, when the first upgraded firmware is determined to be unsafe according to the running state obtained by executing the step 14, closing the virtual machine.
When it is determined that the firmware running in the virtual machine has a security risk according to the running state obtained by executing step 14, the virtual machine is turned off to ensure the security of the running environment of the physical machine, and a security alarm is sent to the upgrade server to prompt the upgrade server that the transmission link of the update package or the encryption scheme of the update package may have been hacked, so that the upgrade server updates the encryption policy and the encryption scheme of the transmission link, and the security of the subsequent transmission process of the update package is ensured.
