In order to improve the security, a person skilled in the art may also select a unique identifier corresponding to the chip as the feature identifier in practice, and the unique identifier cannot be tampered. For example, because information such as a chip manufacturer, a production date, a production line, and an X/Y (lateral/longitudinal) coordinate on a wafer can be obtained through the DIE ID, the DIE ID as a unique ID number of each chip can be selected as a feature identifier of the chip; we may refer to the firmware generated from the chip feature identification as feature firmware. Optionally, the preset device may be connected to the chip hardware to guide the chip to start and read/write data, may perform bidirectional communication with the server, and receives the feature firmware sent from the server and burns the feature firmware into the corresponding chip. The server may be a central server, a cluster server or a distributed server, or may be a cloud server that implements cloud computing and/or cloud storage, and the like.
It should be understood by those skilled in the art that the above firmware, feature identifier, preset device and server are only examples, and suitable changes based on these examples can also be applied to the present invention, and the embodiments of the present invention do not limit the kinds of feature identifiers and preset devices.
The embodiment of the invention provides a chip firmware presetting method, which is applied to presetting equipment, and please refer to fig. 1, wherein the method comprises the following steps:
step S101: guiding a chip to start to obtain a built-in characteristic identifier of 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.
The chip firmware presetting method provided by the embodiment of the invention can acquire the characteristic firmware bound with the chip from the server according to the characteristic identifier of the chip and burn the characteristic firmware into the correspondingly bound chip in the firmware presetting process, 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 booted to obtain a feature identifier embedded in the chip.
In the embodiment of the present invention, the preset device may supply power to the chip, guide the chip to start, and read the feature identifier in the chip through hardware connection, such as a burning seat for placing the chip, and the feature identifier may uniquely correspond to the chip, as described above. Taking an STM32 chip as an example, the burning seat may be included in a burning control module (ST-Link), and the preset device may obtain the feature identifier 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, so as to generate a feature firmware bound to the chip.
In the embodiment of the invention, after the preset equipment acquires the feature identifier, the preset equipment can send a firmware request to the server based on the feature identifier, so that the server generates the feature firmware bound with the chip according to the feature identifier after receiving the firmware request, and sends the feature firmware to the preset equipment.
In a feasible implementation manner, firmware to be burned for realizing a basic function of a chip is stored in a server, and the server may perform encoding based on the firmware to be burned and the feature identifier to generate the feature firmware, so that the feature firmware can be analyzed 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 verified upon activation. For example, the feature identifier may be encoded in a predetermined format to a predetermined position in the firmware to be burned to generate the feature firmware. Of course, the feature identifier may be preprocessed by shifting, encrypting, and the like before encoding, so as to improve the difficulty of cracking. 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 communication verification after the chip is activated. The key and the certificate are the basis in communication verification, the corresponding feature key and/or the feature certificate can be generated according to the feature identifier and combined with the firmware to be burned for communication verification after the chip is activated, so that strong binding of the feature firmware and the corresponding chip is realized, the chip can be successfully activated only when the bound feature firmware is built in, and the chip can be normally used after being activated, 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 is burned into the corresponding chip.
In the embodiment of the invention, after receiving the feature firmware generated by the server according to the method, the presetting device burns the feature firmware onto the corresponding chip bound by the feature firmware to complete the presetting of the chip firmware, so that the feature 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 for each chip, improves the safety of the chip firmware, and can prevent the safety information from being leaked because the presetting equipment can not directly contact the characteristic key and the characteristic certificate. Moreover, 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 feature firmware on each vehicle is realized.
In order to improve the normalization and the safety of chip firmware presetting, in practical application, the whole chip firmware presetting process can be monitored by a server so as to ensure that characteristic firmware is burned under preset equipment corresponding to a preset IP address at strictly specified running time; the burning quantity of the chips, the chip models and the version numbers of the firmware to be burned can be strictly controlled, and the whole operation process is controlled by the server. In a possible implementation manner, the method for presetting the chip firmware provided by the embodiment of the present invention further includes the following pre-step: 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 model, the chip burning quantity, the running time and the version number of the firmware to be burned. For example, the preset device may communicate with the server through the unique code of the preset device before chip firmware is preset, to verify whether the task information meets a predetermined task range, where the predetermined task range may be determined according to the performance of the preset device or the burning requirement. And after the server passes the verification, the server issues the task production information to the preset equipment. Optionally, at this time, the preset device may enter a standby mode, and display information of the production task on a screen for an operator to confirm. 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 process is started. The corresponding different characteristic firmware is respectively burned in different chips in batch, and the mass production efficiency and safety of the chip firmware presetting are improved.
In the chip firmware presetting process, sometimes a firmware burning failure or data transmission abnormality occurs, at this time, the presetting device may mark an operation failure, and in an optional implementation manner of the embodiment of the present invention, a reset operation may also be performed, including the following subsequent steps: and when the burning of the characteristic firmware fails, the chip and the 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 burning fails, the following steps can be automatically executed or executed after a reset button is triggered: and independently powering on and restarting the burning control module, resetting the software of the burning control module, and simultaneously powering on and restarting the chip in which the burning seat is placed, so that the burning failure caused by the running-off of the burning software in the burning control module or the burning failure caused by the hardware failure is prevented. So that it may attempt to resume normal operation by resetting the reboot.
In order to timely troubleshoot problems that may occur during the chip firmware presetting process, in another optional implementation manner of the embodiment of the present invention, the presetting 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 and/or detecting whether the operation of the chip firmware presetting method is normal; and when the abnormality is detected, the chip and the burning control module are electrified again, and the chip firmware presetting method is executed again until the firmware burning is successful. For example, after the self-test button is triggered, whether the burning control module normally operates and whether the connection between the burning control module and the chip hardware in the burning seat is normal can be detected. If the self-check is successful, the burning control module software operates normally, the connection between the burning control module and the burning seat chip is not problematic, and the burning seat source of the burning module can be restarted and the burning module software can be restarted by triggering the reset button.
The chip firmware presetting method provided by the embodiment of the invention can acquire the characteristic firmware bound with the chip from the server according to the characteristic identifier of the chip and burn the characteristic firmware into the correspondingly bound chip in the firmware presetting process, so that the characteristic firmware can only run in the bound chip, and the safety of the chip firmware is improved.
Corresponding to a chip firmware presetting method in an optional implementation manner of the foregoing embodiment of the present invention, an embodiment of the present invention further provides another chip firmware presetting method, where the method is applied to a server, and please refer to fig. 2, where the method includes:
step S201: receiving a firmware request sent by a preset device; the firmware request comprises a characteristic identifier built in a chip guided by the preset equipment;
step S202: generating a 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 issue the characteristic firmware to the presetting device to be burned in the correspondingly 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 comprises a characteristic identifier built in a chip guided by the preset equipment.
In the embodiment of the present invention, as described above, the preset device connected to the server may be connected to the server 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. And after receiving a firmware request sent by the preset equipment, the server generates a feature firmware bound with the chip according to the feature identifier and sends the feature firmware to the preset equipment. Optionally, the feature identifier uniquely corresponds to the chip.
Further, in step S202 in the embodiment of the present invention, a feature firmware bound to the chip may be generated according to the feature identifier.
In a feasible implementation manner, firmware to be burned for realizing a basic function of a chip is stored in a server, and the server may perform encoding based on the firmware to be burned and the feature identifier to generate the feature firmware, so that the feature firmware can be analyzed 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 verified upon activation. For example, the feature identifier may be encoded in a predetermined format to a predetermined position in the firmware to be burned to generate the feature firmware. Of course, the feature identifier may be preprocessed by shifting, encrypting, and the like before encoding, so as to improve the difficulty of cracking. 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 feature key and/or the feature certificate can be generated according to the feature identifier and combined with the firmware to be burned for communication verification after the chip is activated, strong binding of the feature firmware and the corresponding chip can be realized, the chip can be successfully activated only when the bound feature firmware is built in, and the chip can be normally used after being activated, so that 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 feature firmware, the feature firmware is issued to the corresponding preset equipment, so that the preset equipment receives the feature firmware, then the feature firmware is burnt onto the corresponding chip bound by the feature firmware, the presetting of the chip firmware is completed, and the feature firmware can be activated and operated in the corresponding chip. By the chip firmware presetting method provided by the invention, the corresponding characteristic firmware can be generated and burned for each chip, and the safety of the chip firmware is improved. Moreover, 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 feature firmware on each vehicle is realized.
In addition, in order to facilitate the subsequent activation verification, in a possible embodiment of the present invention, the following steps are further included: recording chip information and/or characteristic data of a chip burned with the characteristic firmware for activation verification and/or communication verification of the chip in terminal equipment; the chip information represents that the activation state of the chip is an inactivated state; the feature data includes at least one of the feature identification, feature key, and feature certificate. After the characteristic firmware is generated, the server can record relevant information or data of the chip bound by the characteristic firmware and store the information or data in the database so as to verify the chip in the subsequent activation process. For example, in an optional implementation manner, the server may record chip information representing the chip activation condition, and since the chip has not shipped from the factory at this time, the chip is represented in an inactive state by the current chip information. In the subsequent chip activation process, if the server verifies that the chip information corresponding to the server is in an inactivated state, the activation is legal, and the 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 represented to be in an activated state, and the chip is prevented from being stolen or illegally activated. Since the key and the certificate may be used for verification in communication verification, in another alternative implementation, the server may record feature data of the chip, where the feature data may specifically include at least one of the feature identifier, the feature key, and the feature certificate, so as to perform activation verification and/or communication verification during activation or use of the chip, and only when the feature data or the feature data based on the feature data passes verification, it may be determined that the chip has the correspondingly generated feature firmware built therein, so that the chip passes activation verification and/or communication verification, so as to implement normal operation of the chip in the terminal device. In a specific implementation, the server may query feature data corresponding to the feature firmware bound to 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 secret key and/or the characteristic certificate of the chip. Only when the chip is internally provided with the correspondingly generated feature firmware, the corresponding feature key and/or the corresponding feature certificate can be generated according to the feature firmware, so that the chip passes activation verification and/or communication verification through verification of the signature information. The chip firmware is effectively prevented from being stolen, falsely used or replaced, and the safety of the chip firmware is improved.
In order to improve the normalization and the safety of chip firmware presetting, in practical application, the whole chip firmware presetting process can be monitored by a server so as to ensure that characteristic firmware is burned under preset equipment corresponding to a preset IP address at strictly specified running time; the burning quantity of the chips, the chip models and the version numbers of the firmware to be burned can be strictly controlled, and the whole operation process is controlled by the server. In a possible implementation manner, the method for presetting the chip firmware provided by the embodiment of the present invention further includes the following pre-step: acquiring task information; the task information includes at least one of: the method comprises the steps of presetting a serial number of equipment, an IP address of the equipment, the running time of the equipment, a chip model, the chip burning quantity and the version number of firmware to be burned; and when the task information conforms to a preset task range, issuing the task information to the preset equipment and executing the subsequent steps. For example, an operator may enter task information, and the server verifies whether the task information meets a predetermined task range after acquiring the task information, where the predetermined task range may be determined according to the performance of a preset device or a burning requirement. And after the server passes the verification, the server issues the task production information to the preset equipment. Optionally, at this time, the preset device may enter a standby mode, and display information of the production task on a screen for an operator to confirm. After the task information is confirmed, the chip firmware preset flow can be started. The corresponding different characteristic firmware is respectively burned in different chips in batch, and the mass production efficiency and safety of the chip firmware presetting are improved.
