[0040] The terminal devices, electronic devices and servers involved in the embodiments of the present application may include various handheld devices with wireless communication functions, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to a wireless modem, as well as various forms of user equipment (UE), mobile stations (MS), terminal devices, etc. For the convenience of description, the above-mentioned devices are collectively referred to as electronic devices.

[0041] See also Figure 2A , Figure 2A : is a flowchart of a flashing method provided in an embodiment of the present application. The flashing method described in this embodiment is applied to a terminal device. The method may include the following steps:

[0042] Step 201: A terminal device receives a first digitally signed form sent by an electronic device.

[0043] Among them, the first table includes at least one message digest; it should be noted that the first table only includes the message digests corresponding to part or all of the flashing commands in the flashing package.

[0044] The message digest is generated by calculating the hash value based on the flash command in the flash package.

[0045] Step 202: The terminal device verifies the digital signature information of the first form.

[0046] Specifically, the terminal device has a built-in flash verification tool installed by the manufacturer when it leaves the factory. The built-in flash verification tool is signed by the manufacturer and cannot be changed. The digital signature information of the first form is also signed by the manufacturer. By verifying the digital signature information of the first form with the built-in flash verification tool, it can be determined whether the flash package corresponding to the first form is a genuine flash package.

[0047] Step 203: If the digital signature information of the first table passes the verification, the terminal device determines the version information of the flash package according to the first table.

[0048] Step 204: The terminal device determines whether the flash package is a preset version of firmware based on the version information.

[0049] Step 205: If yes, the terminal device performs a data verification operation to fully verify the flash package.

[0050] Step 206: The terminal device upgrades the firmware of the mobile terminal according to the verified flash package.

[0051] It can be seen that in the embodiment of the present application, the terminal device first receives the digitally signed first form sent by the electronic device, and the first form includes at least one message digest; secondly, the digital signature information of the first form is verified; if the digital signature information of the first form passes the verification, the version information of the flash package is determined according to the first form; secondly, it is determined whether the flash package is a firmware package of a preset version according to the version information; if so, a data verification operation is performed to fully verify the flash package; the firmware of the mobile terminal is upgraded according to the verified flash package. It can be seen that the terminal device first verifies the digital signature of the form, which improves the security when flashing; when the digital signature passes the verification, the terminal device further determines the version information of the flash package, and when the version information is adapted, the flash package is completely flashed, avoiding the situation of incorrect firmware package acquisition and incorrect flash version.

[0052] In one possible example, the data verification operation includes the following steps: detecting whether the currently processed table is an unprocessed table; if so, determining the firmware data corresponding to the first type of message digest in the currently processed table; verifying the firmware data corresponding to the first type of message digest; and under the condition that the verification passes, detecting whether the currently processed table includes a second type of message digest, the second type of message digest including a preset hash value of a second table.

[0053] Among them, the first type of message digest is generated according to the flashing command; the specific method for verifying the firmware data corresponding to the first type of message digest includes: determining the actual hash value of the firmware data corresponding to the first type of message digest, obtaining the preset hash value in the currently processed table, and judging whether the preset hash value is the same as the actual hash value. If they are the same, it is determined that the firmware data has passed the verification, otherwise the firmware data has not passed the verification.

[0054] For example, the table currently being processed includes N first-type message digests, where N is a positive integer; each first-type message digest stores a hash value of a corresponding flash command, called a preset hash value; N first-type message digests correspond to N flash commands, and the mobile terminal determines the above N flash commands in the flash package, calculates the actual hash value of each of the N flash commands according to the preset calculation rules, and obtains N actual hash values. When the N actual hash values ​​are the same as the N preset hash values, it is determined that the firmware data corresponding to the first-type message digest in the first table has passed the verification. Specifically, the preset calculation rule can be the SHA256 algorithm.

[0055] The second type of message digest is a preset hash value corresponding to the next table.

[0056] It can be seen that in this example, the terminal device can verify the firmware data in the current table, ensuring the integrity of the firmware data corresponding to the message digest in the current table.

[0057] In a possible example, after detecting whether the currently processed table includes the second type of message digest, the method further includes: if not, determining that the flashing package verification has passed.

[0058] In one possible example, after detecting whether the currently processed table includes a second type of message digest, the method further includes: if so, obtaining a second table and calculating an actual hash value of the second table; determining whether the actual hash value matches the preset hash value; and if so, updating the currently processed table to the second table.

[0059] After determining whether the actual hash value matches the preset hash value and before updating the currently processed table to the second table, the method further includes: updating the status of the currently processed table to a processed status.

[0060] Wherein, after determining whether the actual hash value matches the preset hash value, the method further includes: if not, terminating the data verification operation; and determining that the flashing package has not passed the verification.

[0061] For example, see Figure 2B , Figure 2BIt is a schematic diagram of a message digest table provided in an embodiment of the present application. As shown in the figure, all the message digests corresponding to the flash package constitute three tables. Among them, in Table 1, message digest 0 to message digest 52 are the message digests corresponding to the firmware data in the flash package; message digest 53 is the message digest obtained by calculating the hash value of message digest 54-message digest 181 in Table 2 (message digest 54 to message digest 181 can be regarded as a message, and the hash value of the message is calculated to obtain message digest 53). In Table 2, message digest 54 to message digest 180 are the message digests corresponding to the firmware data in the flash package; message digest 181 is the message digest obtained by calculating the hash value of message digest 182 to message digest 262 in Table 3 (message digest 182 to message digest 262 can be regarded as a message, and the hash value of the message is calculated to obtain message digest 181). Among them, Table 1 is digitally signed, and message digest 0 to message digest 53 are digitally signed. When Table 1 passes the digital signature verification, it means that Table 1 is safe. Message digest 53 in Table 1 is the preset hash value corresponding to Table 2. Since Table 1 is safe, if the actual hash value corresponding to Table 2 calculated is equal to the preset hash value, it can be proved that the information in Table 2 is safe and complete; it realizes the transmission of security without digitally signing both Table 2 and Table 3, making the data redundant and huge. Since there is no message digest corresponding to the next table in Table 3, the message digests of Table 3 are all message digests corresponding to the flashing commands in the flashing package; after the terminal device verifies the flashing data according to the message digest of Table 3, it confirms that the verification of the entire flashing package is completed.

[0062] It can be seen that in this example, the terminal device stores the preset hash value corresponding to the next table (except the last table) in the last message digest in each table. When the first table is digitally signed, secure transmission is achieved, and there is no need to digitally sign each table, which reduces the data processing amount of the terminal device and improves the data processing efficiency of the terminal device.

[0063] In a possible example, after determining whether the actual hash value matches the preset hash value and before updating the currently processed table to the second table, the method further includes: sending an ACK associated with the second table to the electronic device.

[0064] ACK refers to an Acknowledge character. The terminal device sends ACK to the electronic device to indicate that the terminal device has confirmed that the current form is correct and is ready to receive the next form.

[0065] It can be seen that in this example, the terminal device can return ACK to notify the electronic device to send the data of the next form, thereby achieving continuous acquisition of data, ensuring continuous verification of data, and improving the data processing efficiency of the terminal device.

[0066] In a possible example, after determining whether the actual hash value matches the preset hash value, the method further includes: if not, terminating the data verification operation.

[0067] In a possible example, determining the version information of the flashing package according to the first table includes: acquiring first firmware data corresponding to the first type message digest in the first table; and extracting version information in the first firmware data.

[0068] For details, please refer to Figure 2B The first table refers to Table 1, wherein when the flash package is generated, the version information is compiled into the firmware data corresponding to Table 1 in the flash package, so that the terminal device can know the version information at the very beginning of processing. And if the version information is compatible, the flash operation will continue; if the version information is not compatible, the flash operation will be terminated.

[0069] It can be seen that in this example, the terminal device can first obtain the version information, which makes it easier for the terminal device to perform subsequent operations according to the version information, thereby improving the intelligence of the terminal device.

[0070] In one possible example, before receiving the digitally signed first form sent by the electronic device, the method also includes: sending a flash request message to the electronic device; receiving response message from the electronic device, the response message including a request for obtaining device information; and sending device information of the terminal device to the electronic device.

[0071] It can be seen that in this example, the terminal device sends a flashing request and device information to the electronic device so that the electronic device can identify the identity of the terminal device and then execute an adapted flashing strategy.

[0072] With the above Figure 2A Consistently, see Figure 3 The flashing method described in this embodiment, the terminal device, the method may include the following steps:

[0073] Step 301: The terminal device sends a flash request message to the electronic device.

[0074] Step 302: The terminal device receives response information from the electronic device, where the response information includes a request for obtaining device information.

[0075] Step 303: The terminal device sends device information of the terminal device to the electronic device.

[0076] Step 304: The terminal device receives the digitally signed first form sent by the electronic device.

[0077] Step 305: The terminal device verifies the digital signature information of the first form.

[0078] Step 306: If the digital signature information of the first table passes the verification, the terminal device determines the version information of the flash package according to the first table.

[0079] Step 307: The terminal device determines whether the flash package is a firmware package of a preset version according to the version information.

[0080] Step 308: If the flash package is a firmware package of a preset version, the terminal device detects whether the currently processed form is an unprocessed form.

[0081] Step 309: If the table currently being processed is an unprocessed table, the terminal device determines the firmware data corresponding to the message digest of the first type in the table currently being processed.

[0082] Step 310: The terminal device verifies the firmware data corresponding to the first type of message digest.

[0083] Step 311: Under the condition that the verification is passed, the terminal device detects whether the table currently being processed includes a second type of message digest, and the second type of message digest includes a preset hash value of the second table.

[0084] Step 312: If the currently processed table does not include the second type of message digest, the terminal device generates a flash package based on the firmware data in all the received tables; if the currently processed table includes the second type of message digest, the second table is received and the actual hash value of the second table is calculated; it is determined whether the actual hash value matches the preset hash value; if so, the currently processed table is updated to the second table.

[0085] It can be seen that in the embodiment of the present application, the terminal device first receives the digitally signed first form sent by the electronic device, and the first form includes at least one message digest; secondly, the digital signature information of the first form is verified; if the digital signature information of the first form passes the verification, the version information of the flash package is determined according to the first form; secondly, it is determined whether the flash package is a firmware package of a preset version according to the version information; if so, a data verification operation is performed to fully verify the flash package; the firmware of the mobile terminal is upgraded according to the verified flash package. It can be seen that the terminal device first verifies the digital signature of the form, which improves the security when flashing; when the digital signature passes the verification, the terminal device further determines the version information of the flash package, and when the version information is adapted, the flash package is completely flashed, avoiding the situation of incorrect firmware package acquisition and incorrect flash version.

[0086] With the above Figure 2A Consistently, see Figure 4 , is a flow chart of another flashing method provided in an embodiment of the present application, which is applied to an electronic device. The method may include the following steps:

[0087] Step 401: The electronic device receives a flash request message sent by a terminal device.

[0088] Step 402: The electronic device sends a response message to the terminal device, where the response message includes a request for obtaining device information of the terminal device.

[0089] Step 403: The electronic device receives the first device information sent by the terminal device.

[0090] Step 404: The electronic device sends first device information and second device information to the server, where the second device refers to device information of the electronic device.

[0091] Step 405: The electronic device receives the authorization information sent by the server.

[0092] Step 406: The electronic device determines whether the terminal device meets the flashing condition based on the authorization information.

[0093] Step 407: If yes, the electronic device sends a flash package to the terminal device.

[0094] It can be seen that in the embodiment of the present application, the electronic device receives the flashing request information sent by the terminal device; sends response information to the terminal device, the response information includes a request to obtain the device information of the terminal device; receives the first device information sent by the terminal device; sends the first device information and the second device information to the server, the second device refers to the device information of the electronic device; receives the authorization information sent by the server; determines whether the terminal device meets the flashing conditions according to the authorization information; if so, sends the flashing package to the terminal device. It can be seen that in this example, the electronic device interacts with the terminal device to obtain the device information of the terminal device; the electronic device interacts with the server to obtain the server's interactive information on the electronic device and the terminal device, thereby realizing the server's verification of the terminal device and the electronic device, and improving the security of flashing.

[0100] If yes, then perform a data verification operation to fully verify the flash package;

[0101] The firmware of the mobile terminal is upgraded according to the verified flashing package.

[0102] It can be seen that in the embodiment of the present application, the terminal device first receives the digitally signed first form sent by the electronic device, and the first form includes at least one message digest; secondly, the digital signature information of the first form is verified; if the digital signature information of the first form passes the verification, the version information of the flash package is determined according to the first form; secondly, it is determined whether the flash package is a firmware package of a preset version according to the version information; if so, a data verification operation is performed to fully verify the flash package; the firmware of the mobile terminal is upgraded according to the verified flash package.

[0103] In one possible example, in terms of performing the data verification operation, the instructions in the program are specifically used to perform the following operations: detect whether the currently processed table is an unprocessed table; if so, determine the firmware data corresponding to the first type of message digest in the currently processed table; verify the firmware data corresponding to the first type of message digest; and under the condition that the verification passes, detect whether the currently processed table includes a second type of message digest, and the second type of message digest includes a preset hash value of the second table.
