Background technique

At present, there are two types of update packages (or called update packages) of firmware on terminals such as mobile phones, one is a full update package, and the other is a differential update package.

When the terminal needs to update the firmware, it can request the server to obtain the firmware update package. The server compares the terminal firmware with the firmware of each version stored on the server according to the version number based on the firmware. If the terminal firmware version is not the latest , the server can search for the differential update package used to upgrade the firmware of the terminal to the latest version. If there is such a differential update package, the differential update package can be used to perform a differential update on the firmware on the terminal. If there is no such differential update package, you can use The full update package (that is, the latest version of firmware) performs full update of the firmware on the terminal.

However, in some scenarios, a user or an attacker may obtain permission to operate the terminal firmware, for example, use a third-party tool to obtain the terminal superuser authority, and then modify the terminal firmware. In such cases, although the version number of the terminal's firmware has not changed, the actual content of the terminal's firmware and the firmware of the same version number saved by the server are no longer consistent, which may lead to the failure of using the differential update package to update the terminal's firmware, and , even if you try again, the terminal will still get the differential update package, and the firmware of the terminal cannot be successfully updated.

detailed description

In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with specific embodiments of the present application and corresponding drawings. Apparently, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

Figure 1 is the information update process provided by the embodiment of the present application, which specifically includes the following steps:

S101: Obtain verification information corresponding to specific information on the terminal.

The execution subject of the information update method provided in the embodiment of the present application may be: a server, a terminal, or a system. The execution subject does not constitute a limitation of the present application. For the convenience of description, the embodiments of the present application all take the execution subject as an example for description.

In the embodiment of the present application, the specific information may be software or other specific files on the terminal, wherein, firmware (Firmware) is a typical software on the terminal, generally, the firmware is written into the Erasable Programmable Read-Only Memory (Electrically Erasable Programmable Read-Only Memory, EEPROM), or solidified in the read-only memory (Read-Only Memory, ROM) of the terminal, is software that directly interacts with the underlying hardware of the terminal. For example, for a personal computer (Personal Computer, PC) terminal, the Basic Input Output System (Basic Input Output System, BIOS) solidified in the ROM on the PC motherboard is the firmware of the PC; The mobile phone operating system in the flashROM is exactly the firmware of the mobile phone. For ease of description, the embodiments of the present application are all based on the application scenario in which the specific information is firmware on the terminal, and describe the information update method provided in the embodiments of the present application.

Generally, the firmware on the terminal can be regularly or irregularly updated (updated, also referred to as an upgrade), so that the firmware is consistent with the latest version of the firmware stored on the server, thereby improving the functions and functions of the operating system on the terminal. and/or fix bugs in the operating system on the terminal.

In the prior art, when the firmware on the terminal is to be updated, the terminal can initiate a firmware update request to the server, and the server can save the latest version of the firmware itself, or the download address of the latest version of the firmware sent to the terminal, and then through the terminal, the firmware of the terminal is fully updated, that is, the firmware of the terminal is replaced with the latest version of the firmware, so that the firmware of the terminal is updated to the latest version; further, in practical applications, If a full update is performed each time, the burden on the terminal and traffic consumption will increase. Therefore, when the firmware on the terminal is to be updated, the terminal can also carry its own firmware version number in the firmware update request initiated to the server. Then the server can determine the difference between the firmware of the terminal and the latest version of the firmware by comparing the versions of the two, and can find the saved differential update package corresponding to the difference, and store the differential update package, Or send the download address of the differential update package to the terminal, and then through the terminal, perform a differential update on the firmware of the terminal, that is, use the differential update package to incrementally update or partially replace the firmware of the terminal (which may be collectively referred to as differential update ), so that the firmware of the terminal is updated to the latest version.

However, in some scenarios, users or attackers may obtain permission to operate the terminal firmware. For example, use a third-party tool to root the terminal to obtain superuser privileges, and then modify the terminal firmware. In such cases, although the version number of the terminal's firmware has not changed, the actual content of the terminal's firmware and the firmware of the same version number saved by the server are no longer consistent, which may lead to the failure of the above-mentioned differential update of the terminal's firmware, and , even if you try again, the terminal will still get the differential update package, and the firmware of the terminal cannot be successfully updated.

Based on the above reasons, in the embodiment of the present application, before updating the firmware of the terminal, the server can obtain the verification information of the firmware, which is used to verify the firmware to determine whether the firmware has been modified, so as to determine How to update the firmware in the future.

In addition, it should be noted that, in addition to the above-mentioned process initiated by the terminal to update the firmware, the process of updating the firmware can also be initiated by the server. Specifically, whenever a new version of the firmware is saved on the server, it can actively update The new version of the firmware is pushed to the terminal for real-time firmware update, or the terminal can temporarily save the new version of the firmware pushed by the server, and the user determines when to perform the firmware update.

S102: Determine whether the verification information conforms to a preset result, if yes, execute step S103, otherwise, execute step S104.

S103: Determine to perform a differential update on the specific information.

S104: Determine to perform a full update on the specific information.

It should be noted that after the server determines the update method for the specific information on the terminal, it actively pushes the corresponding update package (differential package or full package) to the terminal, and the terminal updates the specific information on itself after receiving the update package. The information is updated differentially or in full. Alternatively, the server may only prompt the terminal to determine the update method, and the terminal downloads the corresponding update package from the server, and then performs differential update or full update of specific information on itself, and so on. Therefore, the present application does not limit the execution subject that subsequently executes the corresponding update action after the server determines the update mode. Obviously, the execution subject can be either a terminal or a server.

Through the above method, the server can determine whether the firmware has been modified according to the verification information of the firmware on the terminal. The firmware on the terminal can be differentially updated, and then the firmware on the terminal can be successfully updated.

In the embodiment of the present application, for the above step S101, obtaining the verification information corresponding to the specific information on the terminal includes: receiving the verification information sent by the terminal, wherein the verification information is based on the specific information on the terminal information, the check information specifically includes identification information and feature information of the specific information. Wherein, the feature information may be any information that can be used to determine whether the specific information has been modified.

More specifically, when the specific information is firmware, the identification information specifically includes a version number, and the feature information specifically includes system space (system space can also be called: size or size), message digest, cyclic redundancy At least one of the remaining check codes. By checking the feature information, it can be determined whether the firmware on the terminal has been modified, and then the firmware is updated in an applicable manner, so that the firmware can be updated successfully.

Further, in practical applications, the terminal may generate the verification information of the firmware according to its own firmware, where the verification information specifically includes the version number and feature information of the firmware. Generally, the version number can be obtained by reading the configuration file of the firmware, and for feature information, a corresponding generation method can be adopted according to the specific situation. The embodiment of the present application lists three types (system space, message digest, cyclic redundancy check code) as characteristic information, of course, any other characteristic value that can reflect whether the firmware has been modified can also be used as characteristic information, and the selection of said characteristic value does not constitute a limitation to this application.

Here, the manner of generating feature information is briefly described for these three kinds of characterization values.

The system space is selected as the characteristic information. The system space can be expressed in units such as bytes or bits. When the firmware is modified, the system space of the firmware will also change. Calculate the system space of all the files contained in the firmware, which is the system space of the firmware. space.

The message digest is selected as the characteristic information. The message digest is based on a one-way hash algorithm, and the unique fixed-length value corresponding to a message or file is determined. When the firmware is modified, the message digest of the firmware will also change. Commonly used one-way hash algorithms include: Message Digest Algorithm 5 (MD5), Secure Hash Algorithm (SHA), and Message Authentication Code (MAC).

The cyclic redundancy check code is selected as the feature information. The cyclic redundancy check code is based on the modulo operation, and the value corresponding to a fixed length of a message or file is determined. When the firmware is modified, the cyclic redundancy check of the firmware The code will also change.

Further, for the above step S102, judging whether the verification information conforms to the preset result specifically includes: on the server, searching for standard information corresponding to the verification information, generating characteristic information of the standard information, and judging the Whether the characteristic information contained in the verification information is the same as the characteristic information of the standard information, if yes, determine that the verification information conforms to a preset result, otherwise, determine that the verification information does not conform to a preset result.

Furthermore, on the server, searching for the standard information corresponding to the verification information specifically includes: on the server, searching for each standard information stored in advance, wherein each standard information contains its own identification information, in Among the searched standard information, determine the standard information containing the same identification information as the identification information contained in the verification information, as the standard information corresponding to the verification information.

Here, the standard information is described. All standard information is pre-stored on the server. When the specific information does not exist on the terminal, the terminal can obtain the standard information applicable to itself from the server. After that, the terminal obtains The received standard information can become the specific information on the terminal. Obviously, since the terminal may modify the standard information after obtaining the standard information, the specific information on the terminal may be different from the corresponding standard information on the server, that is, the specific information before being modified is: the same as the specific information The standard information corresponding to the flag information included in the information. Of course, if the terminal does not modify the acquired standard information, then the specific information is the same as the corresponding standard information on the server.

More specifically, when the specific information is firmware on the terminal, the standard information specifically includes firmware that is pre-stored on the server and is applicable to the terminal. After the server obtains the version number and feature information of the firmware on the terminal, it can save the firmware whose version number is the same as the version number of the firmware on the terminal, and determine the feature information of the saved firmware, and then determine the firmware on the terminal. Whether the feature information of the firmware is the same as the saved feature information of the firmware, if so, it can be determined that the firmware on the terminal has not been modified, and a differential update can be determined, otherwise, it can be determined that the firmware on the terminal has been modified, and if the differential update is performed, it may be Failed, therefore, a full update can be determined.

This application does not limit the execution subject and the specific execution method after the server determines the update method of the specific information on the terminal. Here, only two feasible execution methods are illustrated here. For the above steps S104 and S105, determining to perform a differential update on the specific information specifically includes: the server prompts the terminal so that the terminal obtains a differential packet from the server, and uses the obtained differential packet to update itself The specific information is differentially updated to the standard information corresponding to the verification information; determining to update the specific information in full, specifically includes: the server prompts the terminal, so that the terminal obtains the same information from the server The standard information corresponding to the verification information is used, and the obtained standard information is used to update all the specific information on itself to the standard information corresponding to the verification information.

Further, in order to improve the processing efficiency of the server, the server may not determine the feature information in real time after receiving the verification information sent by the terminal, but may pre-determine and save the feature information of each version of the firmware. In this case, After receiving the verification information sent by the terminal, the server can directly search for the characteristic information whose corresponding version number is the same as the version number contained in the verification information in the saved characteristic information according to the version number contained in the verification information , and then compare to determine whether the firmware on the terminal has been modified.

In this embodiment of the present application, in addition to the above-mentioned method of sending verification information from the terminal to the server, a method of sending verification information from the server to the terminal may also be used to implement the information update process. Specifically, according to the version number of the terminal, the server can determine the verification information of the firmware of the version number stored by itself, and send it to the terminal. Then, the terminal compares the received verification information with the verification information generated according to the firmware on the terminal. Compare the verification information, judge whether the firmware on the terminal has been modified, and send the judgment result to the server, then the server can check the firmware on the terminal through the terminal when the judgment result is yes. Perform a full update, and when the judgment result is no, you can perform a differential update on the firmware on the terminal through the terminal. Compared with the former method, this method increases the number of interactions between the terminal and the server, but can reduce the load on the server. These two methods can be selected according to the requirements of actual application scenarios.

In addition, if the server sends verification information to the terminal, since the port used by the server may be fixed, hackers may attack the port in a targeted manner and tamper with the verification information sent by the server to each terminal. Therefore, the server can verify the verification information. The verification information is encrypted and signed before being sent to the terminal, thereby improving the security of the interaction process between the server and the terminal; and if the verification information is sent from the terminal to the server, since the terminal generally uses a random port, it increases the security of hackers. The difficulty of the attack, relatively speaking, this method is more secure.

In practical applications, there may also be such a situation: the firmware version on the terminal is far from the latest firmware version, so that many differential update packages need to be obtained to upgrade the firmware on the terminal to the latest version. In this case, compared with differential updating, it may be more efficient to perform a full update of the firmware on the terminal, which can reduce fragmentation of storage space on the terminal and improve the efficiency of the terminal.

In addition, in some scenarios, according to its own security policy, the terminal may record the modification operation of the firmware in the system log. In this case, the terminal and the server may not check the verification information, but only by the The terminal directly determines whether its own firmware has been modified according to the system log, and if so, requests a full update to the server; otherwise, requests a differential update to the server. It should be noted that, generally, the system log of the terminal may not be read when the superuser authority is not obtained.

In the embodiment of the present application, the specific information can also be other information except firmware. Therefore, correspondingly, when judging whether the verification information corresponding to the other information conforms to the preset result, the other information can also be Do other processing than update. The processing includes, but is not limited to: operations such as updating, locking, restoring, unpacking, encapsulating, encrypting, and decrypting.

As described in the above steps, when the specific information is the firmware on the terminal, the server can update the firmware in an applicable way according to the acquired verification information of the firmware on the terminal , so that the firmware can be updated successfully.

Figure 2 is an information update process corresponding to Figure 1 provided by the embodiment of the present application, which specifically includes the following steps:

S201: The terminal generates corresponding verification information for specific information on itself.

S202: Send the verification information to the server.

S203: After receiving the differential update prompt sent by the server, perform a differential update on the specific information, and after receiving the full update prompt sent by the server, perform a full update on the specific information, wherein the The differential update prompt is sent by the server after determining that the verification information conforms to a preset result, and the full update prompt is sent by the server after determining that the verification information does not conform to a preset result.

The specific information specifically includes firmware on the terminal, the verification information specifically includes identification information and feature information of the specific information, the identification information specifically includes a version number, and the feature information specifically includes system space, message digest, At least one of cyclic redundancy check codes.

According to the above description, the detailed process of updating the information provided by the embodiment of the present application is shown in Fig. 3, which specifically includes the following steps:

S301: The terminal generates verification information of its own firmware, and the verification information includes but not limited to a version number, feature information, and the like.

S302: The terminal sends a firmware update request to the server, and the firmware update request carries verification information generated by the terminal.

Based on different application scenarios, the terminal can also send more information to the server at the same time, for example, the model of the terminal, the device identification, and so on.

S303: According to the received version number, the server searches whether there is firmware that can be updated, and if so, executes step S304; otherwise, prompts the terminal that the current version is the latest version.

In addition, in some scenarios, terminals of different models may only use a specific version of firmware. In this case, the latest version of firmware may not be applicable to the terminal. Therefore, the server can filter out the firmware based on the received model. A newer version of the firmware for the terminal.

S304: The server searches for the stored firmware with the version number according to the received version number, and determines the stored feature information of the firmware.

S305: The server compares the received characteristic information with the characteristic information determined by the server, and determines whether the two are the same.

S306: When the two are the same, the server sends a firmware differential update package to the terminal, and when the two are not the same, sends the latest version of the firmware to the terminal.

Alternatively, the server may also send a differential update package of the firmware or a download address of the latest version of the firmware. In addition, in some scenarios, the server does not necessarily have a differential update package. In this case, the firmware on the terminal cannot be updated differentially, and only a full update can be performed.

S307: According to the information for updating firmware provided by the server, the terminal correspondingly performs a differential update or a full update of its own firmware, so that its own firmware is updated to the latest version.
