[0057] Please refer to Figure 1 , which shows a schematic diagram of the architecture of a firmware upgrade system provided by an embodiment of the present application. The firmware upgrade system may include: a terminal device 10 and a first server 20.

[0058] The terminal device 10 may be any type of smart device, which may be a mobile terminal or a relatively fixed terminal. For example, the terminal device 10 may be a mobile phone, a computer, a game console, an e-reader, a wearable device, a smart home device, a vehicle, an Internet of Things device, etc.

[0059] The first server 20 communicates and interacts with the terminal device 10 to implement the firmware upgrade of the terminal device 10. For example, the first server 20 can provide the terminal device 10 with a data packet required for the firmware upgrade, or provide the address of the data packet required for the firmware upgrade. For another example, the first server 20 can retry or resume the firmware upgrade process of the terminal device 10 according to an error that occurs during the firmware upgrade process of the terminal device 10.

[0060] Alternatively, if Figure 1 As shown, the firmware upgrade system may further include a second server 30. The second server 30 communicates and interacts with the first server 20 to provide background management for the firmware upgrade of the terminal device 10. For example, the second server 30 may display the progress and status of the firmware upgrade, initiate the firmware upgrade, upload the data packets required for the firmware upgrade, and the like.

[0061] like Figure 1As shown, the first server 20 and the second server 30 can both be components of the developer center console. The firmware developer can upload the data packets required for the firmware upgrade, view the progress and status of the firmware upgrade, etc. through the second server 30, and can also manage the transmission method of the data packets required for the firmware upgrade through the first server 20.

[0062] In one example, the firmware upgrade method provided in the embodiment of the present application is implemented through OTA (Over-the-Air) technology, and the terminal device 10 and the first server 20 communicate based on the MQTT (Message Queuing Telemetry Transport) protocol; based on this, the first server 20 can be implemented as an MQTT Broker (MQTT proxy server), and the second server 30 can be implemented as an OTA server. Of course, the devices in the firmware upgrade system can also communicate based on other communication protocols, such as HTTP (HyperText Transfer Protocol), LwM2M (Lightweight M2M, Lightweight M2M (Machine-to-Machine, Device to Device)) protocol, etc., and the embodiment of the present application does not limit this.

[0063] Please refer to Figure 2 , which shows a flowchart of a firmware upgrade method provided by an embodiment of the present application. The firmware upgrade method can be applied to Figure 1 In the firmware upgrade system shown in FIG. 1 , for example, the firmware upgrade method may be performed by Figure 1 The terminal device and the first server in the firmware upgrade system shown in the figure interact with each other. Figure 2 As shown, the firmware upgrade method includes the following steps (steps 110 to 130):

[0064] Step 110: The first server sends m data slices and a first firmware check value of the target firmware to the terminal device;

[0065] Step 120: The terminal device calculates a second firmware check value of the target firmware according to the m data slices;

[0066] Step 130: If the second firmware check value is equal to the first firmware check value, the terminal device assembles the m data fragments into a firmware data packet; wherein the firmware data packet is used to upgrade the target firmware in the terminal device.

[0067] The terminal device includes a target firmware, which may be any firmware in the terminal device or a specific firmware preset in the terminal device. The firmware upgrade process of the target firmware may be initiated by the terminal device, or by the first server, or by the above Figure 1 The embodiment of the present application does not limit this. For example, in the case where the firmware upgrade process is initiated by the terminal device, before step 110, the terminal device can send a firmware upgrade request to the first server, and then the first server executes step 110 in response to the firmware upgrade request. For another example, in the case where the firmware upgrade process is initiated by the first server, the first server can execute step 110 when there is an update to the data packet of the target firmware, or the first server can execute step 110 every preset time (such as every half a month). For another example, in the case where the firmware upgrade process is initiated by the second server, before step 110, the second server can send the data packet required for the firmware upgrade to the first server, and the first server executes step 110 in response to receiving the data packet.

[0068] In an embodiment of the present application, the firmware data packet required for the target firmware upgrade in the terminal device can be divided into m data slices, where m is a positive integer. Optionally, multiple channels can be established between the terminal device and the first server, and one or more data slices can be transmitted through a channel between the terminal device and the first server. The embodiment of the present application does not limit the correspondence between the transmission of multiple channels and multiple data slices, and can be flexibly set according to the needs in actual applications. Of course, only one channel for transmitting the data required for the upgrade can be established between the terminal device and the first server, so that m data slices are transmitted through the same channel.

[0069] The first server may send the first firmware check value of the target firmware to the terminal device while sending the m data slices to the terminal device; or may send the first firmware check value of the target firmware to the terminal device after sending the m data slices to the terminal device. The embodiment of the present application does not limit the specific type of the first firmware check value. Optionally, the first firmware check value may be a check value calculated based on a hash value or a checksum value.

[0070] After receiving the data fragment, the terminal device can calculate the second firmware check value of the target firmware by itself. The second firmware check value and the first firmware check value are check values ​​calculated based on the same method. For example, the terminal device and the first server can pre-agree on the calculation method of the check value, and then each checks the firmware check value according to the pre-agreement calculation method. Among them, the firmware check value calculated by the first server is called the first firmware check value in the embodiment of the present application, and the firmware check value calculated by the terminal device is called the second firmware check value in the embodiment of the present application.

[0071] The terminal device compares the first firmware check value and the second firmware check value. If the second firmware check value is equal to the first firmware check value, the m data slices pass the check. The terminal device assembles the m data slices into a firmware data packet to facilitate upgrading the target firmware in the terminal device. If the second firmware check value is not equal to the first firmware check value, the m data slices fail to pass the check. The terminal device can request the first server to retransmit the m data slices, or can request the first server to retransmit some data slices. Please refer to the introduction of the following embodiment, which will not be elaborated here.

[0072] In summary, the firmware upgrade method provided in the embodiment of the present application improves the reliability of data transmission by dividing the firmware data packet required for the firmware upgrade into multiple data fragments. In addition, in the embodiment of the present application, for the case of using multiple data fragments for transmission, the first server and the terminal device respectively calculate the firmware check value according to the m data fragments, and then the terminal device compares the first firmware check value calculated by the first server with the second firmware check value calculated by the terminal device. If the two are the same, it is considered that the multiple data fragments have passed the check, and the terminal device further assembles the m data fragments into a firmware data packet for firmware upgrade. The embodiment of the present application verifies according to the m data fragments before assembling the m data fragments into a firmware data packet to ensure the integrity and correctness of the firmware data packet assembled by the m data fragments, timely discovers abnormal situations in the firmware upgrade process, and improves the reliability of the firmware upgrade.

[0073] In one example, the above step 110 may further include the following steps (steps 011 to 012):

[0074] Step 011: The first server calculates a first slice check value of each data slice according to the data slice;

[0075] Step 012: The first server calculates a first firmware check value based on the m first slice check values.

[0076] Before sending the first firmware check value to the terminal device, the first server may first calculate the first firmware check value. In the embodiment of the present application, the firmware check value may be calculated based on the slice check values ​​of multiple data slices. Therefore, the first server first calculates the first slice check value of each data slice; then, based on the first slice check values ​​of the m data slices (i.e., the m first slice check values), calculates the first firmware check value of the target firmware.

[0077] The embodiment of the present application does not limit the calculation method of the shard check value. Optionally, the first server can calculate the first shard check value of each data shard based on hash value calculation or checksum value calculation. For example, if the first shard check value is calculated based on the checksum value, the first server can treat each data shard as a series of bytes, and then perform addition operations or XOR operations on these bytes to calculate the first shard check value of the data shard.

[0078] The embodiment of the present application does not limit the specific method of calculating the firmware checksum value based on the slice check value. Optionally, the first server can add the first slice check values ​​of the m data slices to obtain the first firmware check value; or, the first server can perform an XOR operation (such as a pairwise XOR operation) on the first slice check values ​​of the m data slices to obtain the first firmware check value; or, the first server can perform a weighted summation process on the first slice check values ​​of the m data slices to obtain the first firmware check value. Optionally, when performing a weighted summation process on the first slice check values ​​of the m data slices, the weight corresponding to each data slice can be determined based on the priority ranking of the data slice. The higher the priority ranking of the data slice, the greater the weight corresponding to the data slice. Among them, the priority ranking of the m data slices is consistent with the ranking of the degree of influence of the m data slices on the device operation status of the terminal device; or, the priority ranking of the m data slices is consistent with the ranking of the degree of influence of the m data slices on the firmware upgrade process of the target firmware.

[0079] In an example, the above step 120 may include the following steps:

[0080] Step 121: The terminal device calculates a second fragment check value of each data fragment according to the data fragment;

[0081] Step 122: The terminal device calculates a second firmware check value based on the m second slice check values.

[0082] The terminal device calculates the second slice check value of each data slice for the data slice; and then calculates the second firmware check value of the target firmware based on the second slice check values ​​of the m data slices (ie, m second slice check values).

[0083] Optionally, the terminal device may calculate the second shard check value of each data shard based on a hash value calculation or a checksum value calculation, etc. For example, if the second shard check value is calculated based on a checksum value, the terminal device may treat each data shard as a series of bytes, and then perform an addition operation or an XOR operation on the bytes to calculate the second shard check value of the data shard.

[0084] Optionally, the terminal device may add the second slice check values ​​of the m data slices to obtain the second firmware check value; or, the terminal device may perform an XOR operation (such as a pairwise XOR operation) on the second slice check values ​​of the m data slices to obtain the second firmware check value; or, the terminal device may perform a weighted summation process on the second slice check values ​​of the m data slices to obtain the second firmware check value. Optionally, when performing a weighted summation process on the second slice check values ​​of the m data slices, the weight corresponding to each data slice may be determined based on the priority ranking of the data slice, and the higher the priority ranking of the data slice, the greater the weight corresponding to the data slice. Among them, the priority ranking of the m data slices is consistent with the ranking of the degree of influence of the m data slices on the device operating status of the terminal device; or, the priority ranking of the m data slices is consistent with the ranking of the degree of influence of the m data slices on the firmware upgrade process of the target firmware.

[0085] It should be understood that in order to ensure the correctness of the verification process, in the embodiment of the present application, the first server and the terminal device should adopt the same calculation method to calculate the slice check value and the firmware check value. For example, the first server calculates the first slice check value and the first firmware check value based on the checksum value, and the first firmware check value is the sum of the m first slice check values; the terminal device also calculates the second slice check value and the second firmware check value based on the checksum value, and the second firmware check value is the sum of the m second slice check values.

[0086] Optionally, the above step 121 may include: the terminal device calculates the second shard check value of each data shard in response to receiving the data shard; or, the terminal device calculates the second shard check value of each data shard in response to receiving m data shards. That is, the terminal device may calculate the second shard check value of each data shard in real time each time it receives a data shard; or, after receiving each data shard, the terminal device first stores the data shard until all the data shards are received, and then calculates the second shard check value of each data shard in sequence or in parallel.

[0087] To sum up, the firmware upgrade method provided in the embodiment of the present application first calculates the slice check value of each of the m data slices, and then calculates the firmware check value based on the m slice check values. This can make the integrity and correctness of each data slice affect the overall check, thereby improving the reliability of data verification and thus improving the reliability of firmware upgrade.

[0088] In an example, the firmware upgrade method may further include the following steps:

[0089] Step 141: The first server sends m first fragment check values ​​to the terminal device.

[0090] Step 142: The terminal device compares the second fragment check value and the first fragment check value of each data fragment;

[0091] Step 143: If the second slice check values ​​of the m data slices are all equal to the first slice check value, the terminal device calculates the second firmware check value of the target firmware according to the m data slices.

[0092] The first server may also send the first shard check value of each data shard calculated by it to the terminal device. For example, the first server may send the first shard check value of the data shard at the same time as sending the data shard, that is, step 141 may be executed simultaneously with the above step 110; or, the first server may send m first shard check values ​​uniformly after sending m data shards, that is, step 141 may be executed after the above step 110; or, the first server may send m first shard check values ​​before sending m data shards, that is, step 141 may be executed before step 110. The embodiment of the present application does not limit the order of transmission of the first shard check value and the data shard.

[0093] The terminal device will also automatically calculate the second slice check value of each data slice, so that the terminal device can compare the first slice check value and the second slice check value of each data slice. If there is any data slice whose first slice check value is not equal to the second slice check value, the verification of the data slice fails, and the terminal device can request the first server to resend the data slice. If the first slice check value of all data slices is equal to the second slice check value, the verification of all data slices is successful, and the terminal device can further calculate the second firmware check value of the target firmware based on the second slice check values ​​of the m data slices to perform verification as a whole.

[0094] To sum up, the firmware upgrade method provided in the embodiment of the present application first verifies each data slice, and then verifies the whole data slice when all data slices have been verified successfully. This can enrich the verification dimension, thereby improving the accuracy of data verification, and further improving the success rate of firmware upgrade.

[0095] In an example, the firmware upgrade method may further include the following steps:

[0096] Step 151: The first server encrypts each data slice using a first preset key to obtain an encrypted data slice;

[0097] Step 152: The first server sends m encrypted data slices to the terminal device;

[0098] Step 153: For each data slice, the terminal device uses the second preset key to decrypt the data slice to obtain a decrypted data slice; wherein the m decrypted data slices are used to calculate the second firmware check value, and the m decrypted data slices are used to assemble a firmware data packet.

[0099] In the embodiment of the present application, data transmission between the terminal device and the first server can be performed in an encrypted manner. Before the above step 110, the first server executes step 151 to encrypt the data slices. Then, the first server sends m encrypted data slices to the terminal device, that is, "the first server sends m data slices to the terminal device" in the above step 110, including "the first server sends m encrypted data slices to the terminal device" in step 152. After receiving the m encrypted data slices, the terminal device first decrypts them to obtain m decrypted data slices, then verifies them according to the m decrypted data slices, and assembles the m decrypted data slices to obtain a firmware data packet.

[0100] Among them, the first preset key used by the first server for encryption and the second preset key used by the terminal device for decryption can be the same key or a pair of keys (such as a public key and a private key), which is not limited in the embodiment of the present application. The second preset key can be embedded in the target firmware of the terminal device, that is, during the compilation process of the target firmware, the second preset key is embedded in the target firmware; or, the second preset key can be stored in a preset position of the terminal device, and the second preset key can be read from the preset position when the data fragment needs to be decrypted.

[0101] Of course, in actual application, other methods can also be used to verify the identity of the data source, for example, using data signatures or digital certificates. The embodiments of this application do not limit the specific authentication method, and it can be flexibly selected according to needs in actual application.

[0102] To sum up, the firmware upgrade method provided in the embodiment of the present application, in addition to verifying the data required for the firmware upgrade, also performs identity verification on the data source. For example, by transmitting the data required for the firmware upgrade in an encrypted manner, the reliability and authenticity of the data source can be ensured, thereby ensuring the device security of the terminal device during the firmware upgrade process.

[0103] In one example, the above step 110 includes: the first server sends m data slices to the terminal device on n first channels between the terminal device and the first server; wherein one first channel is used to transmit one or more data slices; and n is a positive integer.

[0104] Based on this, the above step 110 includes: the terminal device receives m data slices from the first server on n first channels between the terminal device and the first server.

[0105] In one example, before the above step 110, it also includes: the terminal device sends m data transmission topics to the first server on n first channels; wherein a data transmission topic is used to indicate the transmission of a data slice, and a first channel is used to transmit one or more data transmission topics.

[0106] In the embodiment of the present application, multiple channels are established between the terminal device and the first server, and the multiple channels include n first channels. Among them, the first channel can be a channel dedicated to transmitting data slices, or a channel for transmitting data slices and other data (such as log information, etc.). The multiple channels between the terminal device and the first server can also include other channels other than the first channel, such as the second channel and the third channel, which can be used to transmit other types of information, such as heartbeat packets and log information, etc.

[0107] A first channel is used to transmit one or more data slices. In an embodiment of the present application, the data slices transmitted in two different first channels may be the same or different. Taking a first channel used to transmit a data slice, and the data slices transmitted in any two different first channels are different as an example, the above n is equal to m. Of course, in the case where the number of data slices transmitted by a first channel is multiple, or the data slices transmitted in two different first channels are the same, the above n may not be equal to m, such as n may be less than m or n may be greater than m, and the embodiment of the present application does not limit this.

[0108] Among them, a data transmission topic is used to indicate the transmission of a data slice, and a first channel is also used to transmit one or more data transmission topics. In an embodiment of the present application, for a first channel, if a terminal device sends a data transmission topic to a first server on the first channel, the first server sends the data slice indicated by the data transmission topic to the terminal device on the first channel; if the terminal device sends multiple data transmission topics to the first server on the first channel, the first server sends the data slices indicated by the multiple data transmission topics to the terminal device on the first channel.

Optionally, the terminal device may send m data transmission topics to the first server in sequence, and continue to send the next order of data transmission topics after receiving each data slice from the first server. Optionally, the terminal device may send m data transmission topics to the first server at the same time, and the first server may also return the data slices (m data slices) indicated by the m data transmission topics to the terminal device at the same time. The terminal device may receive the data slices (m data slices) indicated by the m data transmission topics at the same time or in sequence.

In addition, multiple channels are established between the terminal device and the first server, and when a channel is abnormally connected, the transmission task can be undertaken through other channels, which can improve the stability and reliability of data transmission, so as to further improve the stability and reliability of firmware upgrade.
