[0045] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0046] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0047] In smart connected cars, the use of USB (Universal Serial Bus) devices for secure flashing of onboard software packages and copying of vehicle-side data has become a common business scenario. If USB devices (such as USB flash drives) are not effectively authenticated, they may face security risks such as data leakage and malware intrusion. The current technology is to use encrypted USB flash drives with authentication passwords, but hardware encrypted USB flash drives are expensive.

[0048] Taking the cost factor into consideration, the present application provides a solution to detect the vehicle operation mode. When the current operation mode of the vehicle is the configuration mode, it detects whether a USB flash drive is connected. When the USB flash drive is detected, the signature information in the USB flash drive is obtained. The signature information is the second identity information encrypted by the private key. The signature information is decrypted by the public key to obtain the second identity information. The first identity information in the configuration mode and the second identity information are matched to obtain the identity authentication result. Through the above scheme, the USB flash drive can be authenticated by using the signature and verification principle without changing the hardware of the USB flash drive in the business of interacting between the vehicle-side controller and the USB flash drive (executing upgrade package flashing and data copying, etc.). While controlling costs, the security of the USB flash drive in related USB flash drive business usage scenarios is also guaranteed.

[0049] Based on this, the present application embodiment provides a USB flash drive identity authentication method, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the USB flash drive identity authentication method of the present application.

[0050] In this embodiment, the USB flash drive identity authentication method includes steps S10 to S40:

[0051] Step S10, detecting the vehicle operation mode, when the vehicle current operation mode is the configuration mode, detecting whether a USB flash drive is connected.

[0052] It should be noted that the vehicle operation mode can be the current operating or working state of the vehicle. For example, normal driving mode, configuration mode, maintenance mode, etc. Exemplarily, the configuration mode may allow users or technicians to make various settings and adjustments to the vehicle, while the normal driving mode focuses on the safe and efficient operation of the vehicle. The configuration mode can be a specific state in the vehicle operation mode, allowing users or technicians to configure and set the vehicle in detail. Exemplarily, in the configuration mode, the vehicle will provide a series of configuration options, such as adjusting vehicle performance parameters, updating software, configuring vehicle safety settings, etc. USB access refers to inserting a USB flash drive (U disk) into a USB port inside or outside the vehicle. U disk is commonly used for data transmission and storage. In vehicle systems, it can be used to transfer configuration files, software updates, or identity authentication information.

[0053] It should be noted that after the step of detecting the vehicle operation mode, the following steps are included: when the current operation mode of the vehicle is not the configuration mode, initializing the serial port device; when the serial port device initialization is completed, receiving and storing the configuration information output by the host computer; and controlling the vehicle operation mode to switch to the configuration mode according to the configuration information.

[0054] It should be noted that the non-configuration mode can be a state where the vehicle is not currently in the configuration mode, such as normal driving mode, standby mode, maintenance mode, etc. The serial port device is an interface for serial communication between a computer and an external device. In the vehicle system, the serial port device is used to communicate with the host computer (such as a computer, server, etc.) to receive configuration information, software updates or other data. Initializing the serial port device means configuring and preparing the serial port interface to ensure that it can transmit data normally. The host computer is used to configure the vehicle system computer or server, which can interact with the vehicle system through a serial port or other communication interface. Configuration information refers to data used to set or adjust vehicle system parameters. The configuration information includes a public key and an encrypted file. The public key is used to decrypt the encrypted file.

[0055] Step S20, when it is detected that the USB flash drive is connected, the signature information in the USB flash drive is obtained.

[0056] It should be noted that the signature information is the second identity information encrypted by the private key, and the second identity information can be understood as the identity information stored in the USB flash drive. Exemplarily, the second identity information can be a set of random numbers, which are encrypted by the private key, and the encrypted random numbers obtained are the signature information. It can be understood that the signature information can be preset in the USB flash drive.

[0057] Step S30: decrypt the signature information using the public key to obtain the second identity information.

[0058] It should be noted that the public key can be built into the vehicle-side controller. For example, the public key can be configured in the vehicle-side software code by hard coding, or the public key can be burned into the vehicle-side controller on the production line.

[0059] Step S40, obtaining an identity authentication result by matching the first identity information and the second identity information in the configuration mode.

[0060] It should be noted that the first identity information may be identity authentication information pre-stored in the vehicle-side controller, and illustratively, the first identity information may be a set of random numbers. The identity authentication result may be the output of the information matching process, indicating whether the identity of the user or device has been verified.

[0061] In this embodiment, the vehicle operation mode is detected. When the current operation mode of the vehicle is the configuration mode, it is detected whether there is a U disk access. When the U disk access is detected, the signature information in the U disk is obtained. The signature information is the second identity information encrypted by the private key. The signature information is decrypted by the public key to obtain the second identity information. The first identity information in the configuration mode and the second identity information are matched to obtain the identity authentication result. Based on this, in the business of interaction between the vehicle-side controller and the U disk (execution of upgrade package flashing and data copying, etc.), the U disk is authenticated by using the signature and signature verification principle without changing the hardware of the U disk, which controls the cost while ensuring the security of the U disk in the relevant U disk business usage scenarios.

[0062] Reference Figure 2 , Figure 2 This is a flow chart of the second embodiment of the USB flash drive identity authentication method of this application. Figure 1 The first embodiment shown is a second embodiment of the USB flash drive identity authentication method of the present application.

[0063] In the second embodiment, the step S20 includes:

[0064] Step S201, when a USB flash drive is detected to be connected, obtain USB flash drive configuration information.

[0065] It should be noted that the USB configuration information may be data stored in the USB for configuring or controlling the vehicle system, and may include software update packages, private key configuration files, second identity information, and parameter settings.

[0066] It should be noted that when the USB flash drive is not detected, the vehicle-side controller is restarted through the analog switch; when the vehicle-side controller is restarted, the process returns to the step of detecting whether the USB flash drive is connected.

[0067] Exemplarily, the analog switch can be an electronic component or circuit used to control the state of the power supply or other key components of the vehicle-side controller. By restarting the vehicle-side controller through the analog switch, it is possible to attempt to restore or reset the state of the vehicle system when the USB flash drive is not detected. It is understandable that this step of restarting the vehicle-side controller through the analog switch is applied to situations where the USB flash drive cannot be detected normally, such as system freezes, configuration errors, etc.

[0068] Step S202: assigning a preset address to the USB flash drive based on the USB flash drive configuration information.

[0069] It should be noted that the preset address can be a specific communication address or identifier assigned by the vehicle system to the USB flash drive. This address is used to uniquely identify the USB flash drive in the internal network of the vehicle system so that the vehicle system can communicate and exchange data with it.

[0070] Step S203, establishing communication with the corresponding USB flash drive according to the preset address, and obtaining signature information in the corresponding USB flash drive.

[0071] Exemplarily, the vehicle system will establish a communication connection with the corresponding USB flash drive according to a preset address in order to read the signature information in the USB flash drive.

[0072] In this embodiment, when the USB flash drive is not detected, restarting the vehicle-side controller through an analog switch can effectively solve the problem of not being able to recognize the USB flash drive due to system freezes, resource conflicts or configuration errors. This automatic restart mechanism can quickly restore the normal working state of the vehicle-side controller, thereby improving the stability of the entire vehicle system. By cyclically detecting the access of the USB flash drive, and automatically obtaining its configuration information, assigning addresses and establishing communication after detecting the USB flash drive, users can achieve data transmission or software updates without manual intervention. Assigning preset addresses to USB flash drives helps the vehicle system manage USB interface resources more effectively. Through the uniqueness of the address, the vehicle system can ensure that each connected USB flash drive can be accurately identified and associated with the corresponding processing logic. This resource management method improves the operating efficiency and reliability of the vehicle system.

[0073] Reference Figure 3 , Figure 3 This is a flow chart of the third embodiment of the USB flash drive identity authentication method of this application. Figure 2 The second embodiment shown provides the third embodiment of the USB flash drive identity authentication method of the present application.

[0074] In the third embodiment, the step S40 includes:

[0075] Step S401: compare the first identity information and the second identity information in the configuration mode, and determine whether the first identity information and the second identity information match according to the comparison result.

[0076] Exemplarily, the comparison result may be a conclusion obtained by comparing the first identity information and the second identity information. If the two identity information are exactly the same or meet a certain preset matching condition, the comparison result is a successful match; otherwise, the comparison result is a failed match. Exemplarily, the first identity information in the configuration mode is compared with the data of the second identity information decrypted from the USB flash drive to verify whether the identity of the user or device is legitimate.

[0077] Step S402: If the match is successful, the identity authentication result is sent to the host computer through the analog switch so that the USB flash drive can be flashed through the host computer.

[0078] It should be noted that the host computer can be a dedicated computer or vehicle information system, which is used to receive data and instructions sent by the vehicle-side controller and perform corresponding processing or display. USB flash drive is usually used to update the software or configuration information of the vehicle-side controller in the vehicle system. Once the identity authentication is passed, the host computer can flash new software or data to the vehicle-side controller through the USB flash drive.

[0079] It should be noted that after the step of determining whether the first identity information and the second identity information match according to the comparison result, the step further includes: if the match fails, returning to the step of restarting the vehicle-side controller through the analog switch.

[0080] It should be noted that restarting the vehicle-side controller can be to reset the operating state of the vehicle-side controller to the initial state and restart its operating program. In the case of identity authentication failure, restarting the vehicle-side controller can be an effective means to restore the normal operation of the system. By restarting, possible error states or configurations can be cleared and identity authentication can be attempted again.

[0081] In this embodiment, by comparing the first identity information in the configuration mode with the second identity information provided by the user, the system can verify whether the user's identity is legitimate. This identity authentication mechanism effectively prevents unauthorized users or devices from accessing the vehicle system, thereby enhancing the security of the system. Using an analog switch to send the identity authentication result and restart the vehicle-side controller increases the system's flexible control over hardware resources. By sending the identity authentication result to the host computer through the analog switch, so that the USB flash drive can be flashed through the host computer, it is ensured that only authorized users can update the software or data of the vehicle system, thereby improving the reliability of the operation.

[0082] In one implementation, in order to make the entire solution more complete, based on the above embodiments, a specific implementation process is proposed, such as Figure 4 As shown, Figure 4The following is a logic flow chart for the vehicle-side controller to judge the USB flash drive that has been placed with the identity authentication information matching file. After the vehicle-side controller completes the initialization, it determines whether the current machine is in configuration mode. If a USB flash drive upgrade is required, the machine needs to be switched to configuration mode. When the machine is switched to configuration mode, the serial port is used to initialize the device, and the configuration information used for USB flash drive authentication is sent to the vehicle-side controller through the host computer. After the vehicle-side controller stores the configuration information, the configuration is completed, and the configuration mode is entered again to judge, and the next step of USB flash drive insertion detection is entered. If the USB flash drive does not exist, the vehicle-side controller is restarted to enter the USB flash drive insertion detection loop again. If the USB flash drive device is detected, the pre-made signature information is obtained from the USB flash drive to complete the signature verification of the signature information in the USB flash drive. If the information matching and comparison is successful, the authentication pass information is fed back to the host computer on the PC side, and the vehicle-side controller completes the USB flash drive identity authentication, and continues the USB flash drive software flashing or data copying business. If the information matching and comparison fails, jump to restart the vehicle-side controller again.

[0083] In this embodiment, by switching the machine to configuration mode, the system can flexibly receive and store configuration information from the host computer. This mechanism allows the vehicle-side controller to be customized according to different needs or scenarios, improving the flexibility and configurability of the system. By verifying the pre-made signature information in the USB flash drive, the system can confirm the legitimacy and integrity of the USB flash drive and prevent the injection of malware or data. Through the automated upgrade process, the system can quickly complete software updates and data synchronization, improving the system's maintenance efficiency and reducing maintenance costs.
