In order to improve the security, in practice, a person skilled in the art may also select a unique identity identifier corresponding to the chip as the feature identifier, where the unique identity identifier cannot be tampered with. For example, since the manufacturer of the chip, the date of production, the line of production, the X/Y (transverse/longitudinal) coordinates on the wafer, etc. information can be obtained from the DIE ID, the DIE ID can be selected as the unique identity number of each chip as the characteristic identifier of the chip; the firmware generated from the chip feature identification may be referred to as feature firmware.

The server may be a central server, a cluster server or a distributed server, or may be a cloud server for implementing cloud computing and/or cloud storage.
It will be appreciated by those skilled in the art that the above-described several types of firmware, feature identifiers, preset devices and servers are merely examples, and that appropriate changes based on these examples may also be applied to the present invention, and embodiments of the present invention are not limited to the type of feature identifier and preset device.
The embodiment of the invention provides a chip firmware presetting method which is applied to preset equipment, referring to FIG. 1, and comprises the following steps:
step S101: guiding a chip to start, and acquiring a characteristic identifier built in the chip;
step S102: sending a firmware request containing the feature identifier to a server to generate feature firmware bound with the chip;
step S103: and receiving the characteristic firmware sent by the server, and burning the characteristic firmware into the corresponding chip.
According to the chip firmware presetting method provided by the embodiment of the invention, the characteristic firmware bound with the chip can be obtained from the server according to the characteristic identifier of the chip in the firmware presetting process, and the characteristic firmware is burnt in the corresponding bound chip, so that the characteristic firmware can only be activated or operated in the bound chip, and the safety of the chip firmware is improved.
In step S101 of the embodiment of the present invention, a chip may be guided to start, and a feature identifier built in the chip may be obtained.
In the embodiment of the invention, the preset device can be connected through hardware, such as a burning seat for placing a chip, for supplying power to the chip, guiding the chip to start, and reading the characteristic identifier in the chip, wherein the characteristic identifier can be uniquely corresponding to the chip as described above. Taking an STM32 chip as an example, the burning seat can be contained in a burning control module (ST-Link), and the preset equipment can acquire the characteristic identification of the chip through a get_ChipID function.
Further, in step S102 of the embodiment of the present invention, a firmware request including the feature identifier may be sent to a server to generate feature firmware bound to the chip.
In the embodiment of the invention, after the preset device obtains the feature identifier, a firmware request can be sent to the server based on the feature identifier, so that after the server receives the firmware request, the feature firmware bound with the chip is generated according to the feature identifier, and the feature firmware is sent to the preset device.
In a possible implementation manner, the server stores firmware to be burned for realizing the basic function of the chip, and the server can encode based on the firmware to be burned and the feature identifier to generate the feature firmware, so that the feature firmware can be parsed out of the feature identifier for activation verification of the chip. Thus, only when the feature firmware is built into the corresponding chip, the corresponding chip can be authenticated at the time of activation. For example, the feature identification may be encoded in a predetermined format to a predetermined location in the firmware to be burned to generate the feature firmware. Of course, the feature identifier can also be subjected to pretreatment such as shifting, encryption and the like before encoding so as to improve the cracking difficulty. In a specific implementation, the server may further generate a feature key and/or a feature certificate according to the feature identifier, and combine the feature key and/or the feature certificate with the firmware to be burned to generate the feature firmware; the feature key and/or feature certificate is used for communication verification after the chip is activated. The key and the certificate are the basis in communication verification, the corresponding characteristic key and/or the characteristic certificate can be generated according to the characteristic identifier and combined with the firmware to be burned for communication verification after chip activation, so that strong binding of the characteristic firmware and the corresponding chip is realized, the chip can be successfully activated only when the bound characteristic firmware is built in, and the chip can be normally used after activation, and the safety of the chip is improved.
Further, in step S103 of the embodiment of the present invention, the feature firmware sent by the server may be received, and the feature firmware may be burned into the corresponding chip.
In the embodiment of the invention, after the preset device receives the characteristic firmware generated by the server by the method, the characteristic firmware is burnt on the corresponding chip bound with the characteristic firmware to finish the preset of the chip firmware, so that the characteristic firmware can be activated and operated in the corresponding chip. The chip firmware presetting method provided by the invention can burn the corresponding characteristic firmware of each chip, improves the safety of the chip firmware, and can prevent the preset equipment from directly contacting the characteristic key and the characteristic certificate, thereby preventing the leakage of safety information. In addition, the chips can be installed on terminal equipment, such as a vehicle-mounted terminal, and the chips can be adapted to vehicles corresponding to the vehicle-mounted terminal, so that different characteristic firmware on each vehicle is realized.
In order to improve the standardization and the safety of chip firmware presetting, in practical application, the whole process of chip firmware presetting can be monitored by a server so as to ensure that characteristic firmware is burnt under preset equipment corresponding to a preset IP address in strictly specified running time; the number of the chip burning, the chip model and the version number of the firmware to be burnt can be strictly controlled, so that the whole operation process is ensured to be controlled by the server. In a possible implementation manner, the chip firmware presetting method provided by the embodiment of the invention further includes the following pre-steps: receiving task information sent by a server; when the task information accords with a preset task range, executing the subsequent steps; the task information includes at least one of: the serial number of the preset equipment, the IP address of the preset equipment, the chip type, the number of the chip burnt, the running time and the version number of the firmware to be burnt. For example, the preset device may communicate with the server through the unique code of the preset device before the chip firmware is preset, to verify whether the task information accords with the predetermined task range, where the predetermined task range may be determined according to the performance or the burning requirement of the preset device. And after the verification is passed, the server issues the task production information to the preset equipment. Alternatively, the preset device may enter a standby mode at this time, displaying information of the production task on a screen for confirmation by the operator. After the task information is confirmed, the preset operation of the chip firmware can be started, the chip is placed in the burning seat, and the chip firmware preset flow is started. Different corresponding characteristic firmware is respectively burnt in different chips in batches, and the mass production efficiency and the safety of chip firmware presetting are improved.
In the process of presetting the chip firmware, sometimes, the situation of firmware burning failure or abnormal data transmission occurs, and at this time, the preset device can perform resetting operation in an alternative implementation manner of the embodiment of the invention besides marking operation failure, and the method comprises the following subsequent steps: and when the characteristic firmware fails to burn, the chip and a burning control module connected with the chip are electrified again, and the chip firmware presetting method is executed again. For example, when the feature firmware fails to burn, the feature firmware may be automatically executed or executed after the reset button is triggered: and independently powering up and restarting the burning control module, resetting the software of the burning control module, and simultaneously powering up and restarting the burning seat comprising a chip arranged in the burning control module, thereby preventing burning failure caused by the running of the burning software in the burning control module or the burning failure caused by hardware failure. So that an attempt can be made to restore normal operation by resetting the reboot.
In order to timely check possible problems in the chip firmware presetting process, in another optional implementation manner of the embodiment of the present invention, the preset device may further perform a self-checking operation, including the following steps: detecting whether the hardware connection between the burning control module and the chip is normal or not, and/or detecting whether the operation of the chip firmware presetting method is normal or not; and when the abnormality is detected, the chip and the burning control module are powered on again, and the chip firmware presetting method is executed again until the firmware is burned successfully. For example, after the self-checking button is triggered, whether the burning control module operates normally or not and whether the connection between the burning control module and the chip hardware in the burning seat is normal or not can be detected. And if the self-check is successful, the software of the burning control module runs normally, the connection between the burning control module and the burning seat chip is free from problems, and the burning seat source of the burning module can be restarted and the software of the burning module can be restarted by triggering a reset button.
According to the chip firmware presetting method provided by the embodiment of the invention, the characteristic firmware bound with the chip can be obtained from the server according to the characteristic identifier of the chip in the firmware presetting process, and the characteristic firmware is burnt in the corresponding bound chip, so that the characteristic firmware can only run in the bound chip, and the safety of the chip firmware is improved.
Corresponding to one chip firmware presetting method in the alternative implementation manner of the above embodiment of the present invention, the embodiment of the present invention further provides another chip firmware presetting method, where the method is applied to a server, please refer to fig. 2, and the method includes:
step S201: receiving a firmware request sent by preset equipment; the firmware request comprises a characteristic identifier built in a chip guided by the preset equipment;
step S202: generating feature firmware bound with the chip according to the feature identifier;
step S203: and issuing the characteristic firmware to the preset equipment, so that the preset equipment burns the characteristic firmware into the corresponding chip.
The chip firmware presetting method provided by the embodiment of the invention can generate the characteristic firmware bound with the chip according to the characteristic identifier of the chip in the firmware presetting process, and send the characteristic firmware to the preset device to be burnt in the corresponding bound chip, so that the characteristic firmware can only run in the bound chip, and the safety of the chip firmware is improved.
In step S201 of the embodiment of the present invention, a firmware request sent by a preset device may be received; the firmware request contains a feature identifier built in a chip guided by the preset device.
In the embodiment of the invention, as described above, the preset device connected with the server may be connected through hardware, such as a burning seat for placing a chip, to guide the chip to start, read the feature identifier in the chip, and send a firmware request to the server based on the feature identifier. After receiving the firmware request sent by the preset device, the server generates feature firmware bound with the chip according to the feature identifier and sends the feature firmware to the preset device. Optionally, the feature identifier uniquely corresponds to the chip.
Further, in step S202 of the embodiment of the present invention, feature firmware bound to the chip may be generated according to the feature identifier.
In a possible implementation manner, the server stores firmware to be burned for realizing the basic function of the chip, and the server can encode based on the firmware to be burned and the feature identifier to generate the feature firmware, so that the feature firmware can be parsed out of the feature identifier for activation verification of the chip. Thus, only when the feature firmware is built into the corresponding chip, the corresponding chip can be authenticated at the time of activation. For example, the feature identification may be encoded in a predetermined format to a predetermined location in the firmware to be burned to generate the feature firmware. Of course, the feature identifier can also be subjected to pretreatment such as shifting, encryption and the like before encoding so as to improve the cracking difficulty. In a specific implementation, the server may further generate a feature key and/or a feature certificate according to the feature identifier, and combine the feature key and/or the feature certificate with the firmware to be burned to generate the feature firmware; the feature key and/or the feature certificate are used for activation verification and/or communication verification after the chip is activated. The key and the certificate are the basis in communication verification, the corresponding characteristic key and/or the characteristic certificate can be generated according to the characteristic identifier and combined with the firmware to be burned for communication verification after chip activation, so that strong binding of the characteristic firmware and the corresponding chip can be realized, the chip can be successfully activated only when the bound characteristic firmware is built in, and the chip can be normally used after activation, and the safety of the chip is improved.
Further, in step S203 of the embodiment of the present invention, the feature firmware may be issued to the preset device, so that the preset device burns the feature firmware into the corresponding chip.
In the embodiment of the invention, after the server generates the characteristic firmware, the characteristic firmware is issued to the corresponding preset equipment, so that the preset equipment receives the characteristic firmware and burns the characteristic firmware to the corresponding chip bound with the characteristic firmware to finish the preset of the chip firmware, and the characteristic firmware can be activated and operated in the corresponding chip. The chip firmware presetting method provided by the invention can generate and burn the corresponding characteristic firmware for each chip, and improves the safety of the chip firmware. In addition, the chips can be installed on terminal equipment, such as a vehicle-mounted terminal, and the chips can be adapted to vehicles corresponding to the vehicle-mounted terminal, so that different characteristic firmware on each vehicle is realized.
Furthermore, in order to facilitate subsequent activation verification, in a possible embodiment of the present invention, the method further comprises the following steps: recording chip information and/or characteristic data of a chip on which the characteristic firmware is burnt, wherein the chip information and/or the characteristic data are used for activating verification and/or communication verification of the chip in terminal equipment; the chip information characterizes that the activation state of the chip is an unactivated state; the feature data includes at least one of the feature identification, a feature key, and a feature certificate. After generating the characteristic firmware, the server can record the related information or data of the chip bound by the characteristic firmware and store the related information or data in a database so as to verify in the subsequent activation process of the chip. For example, in an alternative implementation, the server may record chip information indicating the activation of the chip, and since the chip is not shipped at this time, the current chip information indicates that the chip is in an inactive state. In the subsequent chip activation process, if the server verifies that the corresponding chip information represents the non-activation state, the activation is legal, and an activation instruction can be issued to the terminal equipment containing the chip after the verification is passed. Furthermore, the server can update the chip information corresponding to the chip after the chip is activated, so that the chip is characterized as an activated state, and the chip is prevented from being stolen or illegally activated. Because the key and the certificate can be used for verification in communication verification, in another alternative implementation manner, the server can record the characteristic data of the chip, wherein the characteristic data specifically can comprise at least one of the characteristic identifier, the characteristic key and the characteristic certificate so as to perform activation verification and/or communication verification in the activation or use process of the chip, and the chip can be determined to be built with the corresponding generated characteristic firmware only when the characteristic data or the verification based on the characteristic data passes, so that the chip passes the activation verification and/or the communication verification to realize the normal operation of the chip in the terminal equipment. In a specific implementation, the server can query feature data corresponding to the feature firmware bound by the chip based on the chip information, and generate signature information according to the feature data; and issuing an activation instruction containing the signature information to the terminal equipment, so that the terminal equipment verifies the signature information according to the characteristic key and/or the characteristic certificate of the chip. Only when the corresponding generated characteristic firmware is arranged in the chip, a corresponding characteristic key and/or characteristic certificate can be generated according to the characteristic firmware, so that the chip can pass activation verification and/or communication verification through verification of signature information. The chip firmware is effectively prevented from being stolen, counterfeited or replaced, and the safety of the chip firmware is improved.
In order to improve the standardization and the safety of chip firmware presetting, in practical application, the whole process of chip firmware presetting can be monitored by a server so as to ensure that characteristic firmware is burnt under preset equipment corresponding to a preset IP address in strictly specified running time; the number of the chip burning, the chip model and the version number of the firmware to be burnt can be strictly controlled, so that the whole operation process is ensured to be controlled by the server. In a possible implementation manner, the chip firmware presetting method provided by the embodiment of the invention further includes the following pre-steps: acquiring task information; the task information includes at least one of: presetting a serial number of the equipment, an IP address of the equipment, running time of the equipment, a chip model number, a chip burning number and a version number of firmware to be burned; and when the task information accords with a preset task range, issuing the task information to the preset equipment, and executing subsequent steps. For example, an operator may enter task information, and the server verifies whether the task information meets a predetermined task scope after acquiring the task information, where the predetermined task scope may be determined according to the performance of the preset device or the recording requirement. And after the verification is passed, the server issues the task production information to the preset equipment. Alternatively, the preset device may enter a standby mode at this time, displaying information of the production task on a screen for confirmation by the operator. After the task information is confirmed, the chip firmware preset flow can be started. Different corresponding characteristic firmware is respectively burnt in different chips in batches, and the mass production efficiency and the safety of chip firmware presetting are improved.
The chip firmware presetting method provided by the embodiment of the invention can generate the characteristic firmware bound with the chip according to the characteristic identifier of the chip in the firmware presetting process, and send the characteristic firmware to the preset device to be burnt in the corresponding bound chip, so that the characteristic firmware can only run in the bound chip, and the safety of the chip firmware is improved.
