[0036] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0037] The terminal device upgrade method provided in this application can be applied to Figure 1 In the application environment shown. Among them, the terminal device 102 communicates with the upgrade server 104 through the network. The terminal device 102 sends an access request instruction to the upgrade server 104, and receives the authentication reply result fed back by the upgrade server 104 based on the access request instruction; the terminal device 102 parses the authentication reply result to obtain corresponding identity authentication information; the identity authentication information includes the access result information of the terminal device and the randomly generated verification information; the terminal device 102 generates a first token based on the verification information when confirming that the access request is successful based on the access result information obtained by parsing; the terminal device 102 obtains the device information, and transmits the first token and the device information to the upgrade server 104, so that the upgrade server 104, based on the received first token, when determining that the terminal device 102 has the download authority, queries the upgrade data package based on the device information, and when the query is successful, feeds back the corresponding upgrade data package download information to the terminal device 102; the terminal device 102 receives the upgrade data package download information fed back by the upgrade server 104, and performs device upgrade according to the upgrade data package download information.

[0038] The terminal device 102 may be, but is not limited to, various personal computers, laptops, smart phones, tablet computers, portable wearable devices, and IoT terminals, and the upgrade server 106 may be implemented as an independent server or a server cluster consisting of multiple servers.

[0039] In one embodiment, Figure 2 As shown, a terminal device upgrade method is provided, which is applied to Figure 1 The terminal device in the example is used to illustrate, including the following steps:

[0040] Step S202: sending an access request instruction to the upgrade server, and receiving an authentication response result fed back by the upgrade server based on the access request instruction.

[0041] Specifically, first, the terminal device receives the upgrade instruction sent by the application server, wherein the upgrade instruction carries the access address of the upgrade server. Secondly, the terminal device parses the received upgrade instruction, and based on the access address of the upgrade server obtained by the parsing, based on the preset communication port, sends an access request instruction to the upgrade server in a directional manner, wherein the access request instruction carries the identification number of the terminal device. Afterwards, after receiving the access request instruction, the upgrade server will parse the access request instruction to determine the identification number of the terminal device, and determine whether the terminal device has access rights based on the identification number of the terminal device obtained by the parsing, and feedback the corresponding authentication reply result to the terminal device.

[0042] In one embodiment, the identification number of the terminal device may be an IMEI (International Mobile Equipment Identity) number. It should be noted that the IMEI number is commonly referred to as a mobile phone serial number, a mobile phone "serial number", etc., which is used to identify each independent mobile phone or other communication device in the network, which is equivalent to the ID card of the terminal device.

[0043] Based on the above embodiment, the terminal device will send an access request instruction to the upgrade server through the following communication interface:

[0044] "https: / / ip:port / fota / api / authent?id={IMEI_NUM}&version={VER SION_NUM}, method=GET";

[0045] Among them, {IMEI_NUM} is the IMEI number of the terminal device; {VERSION_NUM} is the adopted protocol version. It should be noted that the above protocol version refers to the protocol used by the upgrade server to upgrade, and the specific format of the protocol version can be "letter + number", for example: V1.1, etc.

[0046] In one embodiment, after receiving the access request instruction, the upgrade server will reply the following content (i.e., the authentication reply result) to the terminal device:

[0047] "{"state":"{RESULT}","action":"authent","message":"{MESS AGE_INFO}","id":"{IMEI_NUM}","ticket":"{TICKET_NUM}"}";

[0048] Among them, (1) the {RESULT} field is the feedback access result (i.e., the access result information of the terminal device). In one embodiment, the {RESULT} field can be defined as "ok" or "error", where "ok" indicates that the terminal device access is successful, and "error" indicates that the terminal device access fails. The detailed information of the above access result is recorded in the {MESSAGE_INFO} field. It should be noted that the {MESSAGE_INFO} field is the specific content of the access result. For example, the {MESSAGE_INFO} field can record the "imei length error" information indicating the IMEI number length error. (2) {TICKET_NUM} is a randomly generated ticket value (randomly generated verification information). In one embodiment, the ticket can be a 6-bit number from 0 to 9.

[0049] Step S204, parsing the authentication reply result to obtain corresponding identity authentication information; the identity authentication information includes the access result information of the terminal device and the randomly generated verification information.

[0050] Specifically, the terminal device parses the received authentication reply result and obtains the corresponding access result information and the randomly generated verification information. Since the data structure of the authentication reply result, the meaning of the access result information representation, the meaning of the randomly generated verification information representation, and the definable form have been described in detail in the above embodiment, the embodiment of the present application will not be described in detail here.

[0051] Step S206: Based on the access result information obtained through analysis, when it is confirmed that the access request is successful, a first token is generated based on the verification information.

[0052] Specifically, based on the access result information fed back by the upgrade server, when the terminal device determines that it has successfully accessed the upgrade server, it will generate a first token through an information digest algorithm, given the known identification number of the terminal device, a preset specific character string, and verification information. It should be noted that the above-mentioned specific character string is determined in advance by the manufacturers of the terminal device and the upgrade server, and the character string does not pass through the network. Therefore, illegal visitors will not be able to obtain the character string through network monitoring and other means. The randomly generated verification information also ensures that even for the same device, the corresponding token generated each time it is upgraded is different. In addition, the use of the information digest algorithm can also ensure that the token cannot be reversed. In this way, it is ensured that illegal visitors cannot disguise themselves as terminal devices and request the upgrade server to obtain upgrade data packets, further improving the security of device upgrades.

[0053] In one embodiment, the message digest algorithm may be an MD5 (Message-Digest Algorithm, a widely used cryptographic hash function) algorithm. In one embodiment, the terminal device will calculate the terminal device identification number, a preset specific string, and verification information through the MD5 algorithm to obtain a corresponding token field. The token field is a string of characters generated by the terminal device as a token for the client to make a request. The use of the token field can also reduce the pressure on the device, reduce frequent queries to the database, and make the device more robust.

[0054] Step S208, obtain device information, and transmit the first token and device information to the upgrade server, so that the upgrade server can query the upgrade data package based on the device information when it determines that the terminal device has download permission based on the received first token, and when the query is successful, feedback the corresponding upgrade data package download information to the terminal device.

[0055] Specifically, after acquiring the device information, the terminal device transmits the first token and the device information to the upgrade server through a designated transmission interface.

[0056] In one embodiment, the transmission interface is defined as follows:

[0057] "https: / / ip:port / fota / api / check?id={IMEI_NUM}&version={VERS 0ION_NUM}&company={COMPANY}&token={MD5_TOKEN}&prod uct_name={PRODUCT_NAME}&product_version={PRODUCT_VERS ION}, method=GET";

[0058] Among them, {COMPANY} is the manufacturer of the device; {PRODUCT_NAME} is the name of the device project to which the terminal device belongs; {PRODUCT_VERSION} is the device information including the version number of the old program running in the terminal device before the device is upgraded; {MD5_TOKEN} is the verification value obtained by verifying the ticket field based on the MD5 algorithm.

[0059] Specifically, the upgrade server generates a second token based on the same method (e.g., based on an information digest algorithm) when the terminal device identification number and a specific character string agreed upon in advance with the terminal device are known, and compares the received first token with the second token to determine whether the terminal device has download permission. If the upgrade server determines that the terminal device has access rights, it will query the upgrade data package based on the received device information, and if the query is successful, it will transmit the relevant download information of the upgrade data package (e.g., download address, version number) to the terminal device.

[0060] Step S210: receiving the upgrade data package download information fed back by the upgrade server, and performing device upgrade according to the upgrade data package download information.

[0061] Specifically, the terminal device, based on the received upgrade data package download information, determines the download address corresponding to the upgrade data package, accesses the download address, and downloads the upgrade data package from the accessed resources. Subsequently, when the terminal device determines that the upgrade data package is downloaded successfully, it will perform device upgrade based on the downloaded upgrade data package.

[0062] In one embodiment, the terminal device can use the HTTPS (Hyper Text Transfer Protocol over Secure Socket Layer) protocol to access the download address of the upgrade data package, and determine to download the upgrade data package if the access is successful. Of course, in the current embodiment, the terminal device can also use other communication protocols to access the download address of the upgrade data package, such as the FTP (File Transfer Protocol) protocol, etc. The embodiment of the present application does not limit which communication protocol the terminal device uses to access the download address of the upgrade data package.

[0063] In the above terminal device upgrade method, the terminal device sends an access request instruction to the upgrade server, and receives an authentication reply result fed back by the upgrade server based on the access request instruction. The authentication reply result includes access result information and verification information. After that, the terminal device determines based on the access result information that when confirming that the request access is successful, it generates a corresponding first token based on the parsed verification information to obtain the corresponding upgrade data packet through the first token. Among them, the terminal device will only interact with the upgrade server after successfully accessing the upgrade server, which can ensure the security of the interactive identity between the upgrade server and the terminal device, and also avoid the access of illegal visitors, and can ensure the security of the upgrade process. In addition, since the verification information is randomly generated, this operation can also indirectly ensure the variability of the token, so that even if an illegal visitor can steal a token of a certain upgrade stage, he cannot forge a terminal device based on the token, and then request an upgrade data packet from the upgrade server. In addition, before feeding back the upgrade data packet download information to the terminal device, the upgrade server will also determine the download authority of the terminal device based on the received token to avoid the loss of resources caused by feeding back the upgrade data packet download information to the unauthorized device, and further ensure the security of the device upgrade.

[0064] In one embodiment, a first token is generated based on verification information, including: obtaining an identification number of a terminal device and a preset specific string; the specific string is determined in advance through negotiation between the terminal device and an upgrade server; and the identification number of the terminal device, the specific string and the verification information are calculated through an information digest algorithm to generate the first token.

[0065] Specifically, first, the terminal device obtains its own identification number and determines a preset specific string. The preset specific string is negotiated and determined in advance by the terminal device and the upgrade server, and the specific string does not pass through the network. Therefore, illegal visitors (for example, hackers) will not be able to monitor the specific string through illegal means such as network monitoring. After that, the terminal device verifies the obtained terminal device identification number, specific string and ticket field through an information digest algorithm (for example, MD5 algorithm) to obtain the corresponding token field (that is, generate the first token).

[0066] In the above embodiment, the token field is jointly determined by the identification number of the terminal device, a specific string, and a ticket randomly generated by the server. Among them, the specific string is negotiated and determined in advance by the terminal device and the upgrade server, and does not pass through the network. Therefore, illegal visitors cannot obtain it through network monitoring and other means; and the randomly generated ticket ensures that even if it is the same device, the token field is different each time it is upgraded, and the use of the information digest algorithm further ensures that the token field cannot be reversed, so that illegal visitors cannot disguise themselves as terminal devices to request the upgrade server to obtain the upgrade data packet, ensuring the security of the upgrade process.

[0067] In one embodiment, when the upgrade server determines that the terminal device has download permission based on the received first token, the upgrade server queries the upgrade data package based on the device information, including: the upgrade server compares the received first token with a second token determined based on the authentication reply result fed back to the terminal device in advance to obtain a corresponding comparison result; when the upgrade server determines that the terminal device has download permission based on the comparison result, the upgrade server queries the upgrade data package through a background query method based on the received device information; the device information includes at least one of the version number of the old program running in the terminal device before the device is upgraded, the name of the device project to which the terminal device belongs, and the manufacturer of the terminal device.

[0068] Specifically, when the upgrade server knows the identification number of the terminal device, the preset specific character string, and the ticket field (i.e., verification information) randomly generated by itself, it will calculate the above information based on the same verification method, i.e., based on the information summary algorithm, to generate a corresponding second token. Afterwards, after receiving the first token, the first token is compared with the generated second token. Based on the comparison result, when it is determined that the first token matches the second token, the upgrade data packet is queried based on the received device information. In one embodiment, the upgrade server can use a background query method to query the upgrade data packet. Of course, other query methods can also be used, such as a database query method, etc., which is not limited to the embodiments of the present application.

[0069] In one embodiment, the version number of the old program is the version that the device is running before the upgrade, such as "N311-001". The device project name to which the terminal device belongs includes but is not limited to the NWY_N311 project, etc., which is not limited in the embodiment of the present application. The upgrade server can store the upgrade data package in the database in advance in the form of {upgrade data package, device information}, and when it is determined that the terminal device has the download permission, the upgrade data package is queried from the various upgrade data pre-stored in the database using the device information as the query condition.

[0070] In the above embodiment, the upgrade server determines whether the terminal device has access rights based on token comparison, thereby preventing illegal visitors from disguising themselves as terminal devices and requesting upgrade data packets from the upgrade server, thereby ensuring the security of device upgrades.

[0071] In one embodiment, the upgrade server feeds back corresponding upgrade data packet download information to the terminal device when the query is successful, including: the upgrade server determines the download address of the upgrade data packet, the version number of the upgrade data packet, and the token of the upgrade data packet when the corresponding upgrade data packet is queried through the background query method; the upgrade server uses the download address of the upgrade data packet, the version number of the upgrade data packet, and the token of the upgrade data packet as the upgrade data packet download information, and feeds back the upgrade data packet download information to the terminal device.

[0072] Specifically, based on the received first token, the upgrade server will query the upgrade data package through a background query method using the device information as a search condition when it is determined that the terminal device has access rights, and when it is determined that the query is successful, the download address of the determined upgrade data package, the version number of the upgrade data package, and the token of the upgrade data package will be integrated, and the integrated upgrade data package download information will be fed back to the terminal device through the corresponding transmission interface. When it is determined that the query fails, the upgrade server will feed back information that the upgrade request has failed to the terminal device.

[0073] In one embodiment, when the upgrade server determines that the upgrade data packet search is successful, the feedback information is as follows:

[0074] "{"state":"ok","action":"check","message":"{MESSAGE_INF O}","update":true,"product_version":"{PRODUCT_VERSION}","company":"{COMPANY}","file_md5":"{FILE_MD5}","content" :"{CONTENT}","current_version":"{PRODUCT_VERSION}","date":"{DATA_TIME}","url":"{FILE_URL}","id":"{IMEI_NUM}"}";

[0075] in:

[0076] (1) “state” defines the access result of the terminal device. For example, when the content defined in “state” is “ok”, it is considered that the terminal device access is successful; when the content defined in “state” is “error”, it is considered that the terminal device access fails.

[0077] (2) "Action" defines the type of action currently executed by the upgrade service. For example, when its definition is "check", it is considered that the action type executed by the upgrade server is a query type; when its definition is "authent", it is considered that the action type executed by the upgrade server is an identity authentication type.

[0078] (3) "message" defines the detailed information of the returned result. For example, it can be "post paramerror": indicating that the request parameters transmitted are incorrect, etc.

[0079] (4) "update" defines the query result of the upgrade data package. For example, when its definition content is "true", it can be considered that the upgrade data package has been successfully queried. When its definition content is "false", it can be considered that the upgrade data package has not been queried.

[0080] (5) “Company” defines the manufacturer of the terminal equipment.

[0081] (6) “file_md5” defines the token of the upgrade data package.

[0082] (7) "Content" defines the description of the upgrade data package. For example, it can be a description of the upgrade data package. It is an optional part and the content defined therein may be empty.

[0083] (8) “current_version” defines the version number of the upgrade data package. For example, the version number of the upgrade data package defined is “N311-002”.

[0084] (9) “date” defines the time point when the upgrade server stores the corresponding upgrade data package.

[0085] "url" defines the download address of the upgrade data package. "id" defines XXX.

[0086] In one embodiment, receiving upgrade data packet download information fed back by an upgrade server and performing a device upgrade according to the upgrade data packet download information includes: receiving the upgrade data packet download information and parsing the upgrade data packet download information to determine a download address of the upgrade data packet; accessing the download address of the upgrade data packet based on a preset secure communication protocol, and downloading a real-time upgrade data packet from the currently accessed address when it is determined that the address access is successful; upgrading the old program based on the downloaded real-time upgrade data packet, and starting the corresponding upgraded new program when it is determined that the upgrade of the old device is complete.

[0087] Specifically, after receiving the upgrade data packet download information, the terminal device will parse it to obtain the download address of the upgrade data packet. After that, the download address of the upgrade data packet is accessed through a preset secure communication protocol, and the upgrade data packet is downloaded from the accessed address to obtain the corresponding real-time upgrade data packet. After that, the terminal device will upgrade the device based on the downloaded real-time upgrade data packet, and when it is determined that the device upgrade is successful, the new program is started through the preset boot loader, and the startup status of the new program is used to determine whether the device is successfully upgraded.

[0088] In one embodiment, the boot loader may be a bootloader. It should be noted that in an embedded operating system, the boot loader is run before the operating system kernel runs. It can initialize hardware devices and establish a memory space mapping map, thereby bringing the system's software and hardware environment to a suitable state, so as to prepare the correct environment for the final call to the operating system kernel. The preset secure communication protocol may be the HTTPS protocol, the FTPS protocol, etc., which is not limited in the embodiments of the present application.

[0089] In the above embodiment, when sending the upgrade data packet, a secure communication protocol is used. Therefore, even if a hacker obtains the download address of the upgrade data packet during the transmission of the upgrade data packet download information, the hacker cannot parse it, thereby optimizing the security of the upgrade data packet download process and ensuring the security of the entire communication process.

[0090] In one embodiment, before performing an upgrade step of an old program based on a downloaded real-time upgrade data packet, the method includes: parsing the upgrade data packet download information to determine the version number of the upgrade data packet and the token of the upgrade data packet; backing up and storing the parsed version number of the upgrade data packet, the token of the upgrade data packet, and the old program already running in the terminal device through a preset storage partition; determining the token of the real-time upgrade data packet, and comparing the token of the real-time upgrade data packet with the first data of the same type stored in the corresponding storage partition to obtain a corresponding first comparison result.

[0091] For details, please refer to Figure 3 Before upgrading the device, the terminal device will also use the preset storage partition to immediately store the version number of the parsed upgrade data packet, the token of the upgrade data packet, and the old program already running in the terminal device. In this way, when data (such as the version number of the upgrade data packet) needs to be compared later, and when the old program needs to be restored, the corresponding data can be directly retrieved from the storage partition, avoiding the problem that the device cannot work properly when the new program fails to start due to the failure to back up the old program. In addition, the real-time upgrade data packet can be verified based on the pre-stored version number and token of the upgrade data packet. In this way, the upgrade data packet can be prevented from being replaced during the download process, and the wrong upgrade data packet can be upgraded due to human operation errors, which can cause the device to fail to work properly.

[0092] In one embodiment, please refer to Figure 4 , based on the downloaded real-time upgrade data package, upgrading the old program, and, when it is determined that the upgrade of the old device is completed, starting the corresponding upgraded new program, including:

[0093] Step S402: based on the first comparison result, when it is determined that the token of the real-time upgrade data packet matches the first data of the same type, the old program is upgraded based on the downloaded real-time upgrade data packet.

[0094] Specifically, when the terminal device determines that the token of the real-time upgrade data packet matches the corresponding first data of the same type pre-stored in the storage partition, it will upgrade the program based on the downloaded upgrade data packet, and then determine whether the device has been successfully upgraded based on the startup status of the new program obtained by the corresponding upgrade.

[0095] Step S404, when it is determined that the old device upgrade is completed, the corresponding upgraded new program is started through the preset boot loader, and when it is determined that the new program fails to start, the corresponding backed up old program is retrieved from the storage partition and the old program is restored.

[0096] Specifically, the terminal device starts the new program through a preset boot loader, for example, a bootloader, and through the startup status of the new program, when it is determined that the startup of the new program fails, the corresponding old program is retrieved from the storage partition and the old program is restored. In one embodiment, when the terminal device determines that the new program fails, when it is determined that the upgrade server and the application server can be successfully accessed (it should be noted that the upgrade server and the application server can be two independent servers or two services of one server), the instantly generated upgrade failure information is fed back to the application server and the upgrade server, so that the above two servers can immediately take corresponding countermeasures for the current device upgrade failure status.

[0097] Step S406, when it is determined that the new program is started successfully, the version number of the corresponding upgraded new program is determined, and the version number of the new program is compared with the corresponding second data of the same type stored in the storage partition. Based on the second comparison result obtained, when the version number of the new program matches the second data of the same type, it is determined that the terminal device has been upgraded successfully.

[0098] Specifically, when the terminal device determines that the new program has been successfully started, it will verify the validity of the version number of the new program to prevent the upgrade data package in the download process from being illegally replaced without knowing it, and to prevent the wrong upgrade data package from being upgraded due to human operating errors, causing the device to fail to work properly.
