[0002] With the rapid development of automotive electronics technology, car keys, as the product closest to users in the automotive field, are also constantly evolving, iterating from the initial mechanical keys and remote control keys to digital keys. This new key technology will become a standard feature of the next generation of cars. Among them, NFC (Near Field Communication) digital keys are a product form of digital car keys. NFC is a short-range, high-frequency wireless communication technology that allows contactless point-to-point data transmission and exchange between electronic devices. NFC digital keys mainly utilize NFC communication technology, allowing users to quickly unlock, lock, and start the vehicle by tapping an NFC-enabled smart device or physical card against the NFC sensing area on the vehicle. After security authentication is completed between the key and the vehicle, the user can quickly unlock, lock, and start the vehicle.

[0003] However, existing NFC-based vehicle start-up methods have weak security checks on NFC digital keys, resulting in low security for the NFC-based vehicle start-up process. Summary of the Invention

[0039] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0040] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0041] Example 1

[0042] Figure 1A This is a flowchart of a vehicle starting method based on near-field communication provided in Embodiment 1 of the present invention. This embodiment is applicable to the case of starting a vehicle based on the vehicle's near-field communication (NFC) function. The method can be executed by a vehicle starting device based on near-field communication, which can be implemented in hardware and / or software. The vehicle starting device based on near-field communication can be configured in an electronic device, for example, in the vehicle controller of a vehicle control system.

[0043] Figure 1B This is a schematic diagram of a vehicle control system according to Embodiment 1 of the present invention. The vehicle control system 10 includes a vehicle controller 11, a digital key control module 12, and a near-field communication (NFC) module 13. The digital key control module 12 is communicatively connected to both the vehicle controller 11 and the NFC module 13.

[0044] It's worth noting that, to reduce costs, decrease the number of chips, and improve vehicle layout flexibility, the NFC module can be integrated into the vehicle's wireless charging module. This combines the independent NFC and wireless charging functions, supporting both functionalities on a single chip. The NFC module chip is integrated onto the wireless charging PCB (Printed Circuit Board), and the NFC antenna coil and the wireless charging temperature acquisition circuitry are integrated onto the same filter board PCB. This architectural design reduces the number of chips within the controller, lowers costs, and simplifies vehicle layout. Functionally, it reuses a single security chip with the existing digital key control module for vehicle-to-mobile security authentication. The authentication result is provided by the digital key control module, not the wireless charging module. The wireless charging controller and NFC module only transmit data between the two ends without participating in calculations. This implementation logic is compatible with various digital key security protocols, reducing the workload of development and adaptation with mobile phone manufacturers to some extent.

[0045] like Figure 1A As shown, this method is executed by the vehicle controller in the vehicle control system and includes:

[0046] S110. When a vehicle start request initiated by the user terminal based on the NFC function is detected, a secure random number is generated and sent to the digital key control module so that the digital key control module can generate and feed back a first response value based on the secure random number.

[0047] Users can initiate a vehicle start request via the NFC function provided on their user terminal, which can be a mobile phone or tablet. When the vehicle controller detects the vehicle start request, it performs a security verification. This security verification may include anti-theft security verification and access control security verification.

[0048] The vehicle-side controller randomly generates a secure random number and sends it to the digital key control module. The digital key control module calculates the secure random number based on a preset encryption algorithm or key, such as a hash algorithm, to obtain a first response value, and then feeds this first response value back to the vehicle-side controller. The encryption algorithm or key in the digital key control module can be pre-configured by relevant technical personnel. Specifically, it can be the same as the encryption algorithm or key in the vehicle-side controller, or it can be a symmetric encryption algorithm or key; this embodiment does not impose any restrictions on this.

[0049] S120. Perform a security check on the vehicle start request based on the security random number and the first response value.

[0050] The vehicle controller can compare the response value generated by the security random number with the response value fed back by the digital key control module, and then perform security verification on the vehicle start request based on the comparison result.

[0051] In one optional embodiment, a security check is performed on the vehicle startup request based on a secure random number and a first response value, including: generating a second response value based on the secure random number; performing an access security check on the vehicle startup request based on the first and second response values ​​to obtain an access security check result; obtaining user location information of the user terminal and vehicle location information of the vehicle itself; performing an anti-theft security check on the vehicle startup request based on the user location information and vehicle location information to obtain an anti-theft security check result; and performing a security check on the vehicle startup request based on the access security check result and the anti-theft security check result.

[0052] The vehicle controller uses the same or corresponding encryption algorithm or key deployed with the digital key control module to encrypt and calculate a secure random number, obtaining a second response value. The first and second response values ​​are compared for consistency. If they match, the security verification of the vehicle start request's permissions passes; otherwise, the security verification of the vehicle start request's permissions fails.

[0053] The system acquires the user's location information from the user terminal and the vehicle's location information. If the distance between the user's location and the vehicle's location is less than a preset distance threshold, the anti-theft security check for the vehicle startup request passes; if the distance between the user's location and the vehicle's location is not less than the preset distance threshold, the anti-theft security check for the vehicle startup request fails. The distance threshold can be preset by relevant technical personnel; for example, the distance threshold can be set to 2 meters.

[0054] If both the access security check and the anti-theft security check pass, the security check for the vehicle startup request passes; if either the access security check or the anti-theft security check fails, the security check for the vehicle startup request fails.

[0055] To further ensure that the access security detection results have a certain degree of fault tolerance, thereby improving the accuracy of the access security detection results and avoiding deviations in the calculation results of the vehicle controller and digital key control module in a certain calculation cycle due to sudden anomalies, this embodiment also provides a method for accurately determining the access security detection results.

[0056] In one optional embodiment, the vehicle start request is subjected to permission security detection based on the first response value and the second response value to obtain the permission security detection result. This includes: comparing the first response value and the second response value; if the comparison result is inconsistent, at least two reference random numbers are generated in the current iteration cycle, and each reference random number is sent to the digital key control module so that the digital key control module can generate a first reference response value corresponding to each reference random number; generating a second reference response value for each reference random number based on each reference random number; comparing each first reference response value with the corresponding second reference response value to obtain the comparison result of each reference random number in the current iteration cycle; and performing permission security detection on the vehicle start request based on the comparison result of each reference random number in each iteration cycle to obtain the permission security detection result.

[0057] If the comparison results of the first response value and the second response value are inconsistent, a preset iteration period can be set. For example, the preset iteration period can be 5 periods.

[0058] For any preset iteration cycle, in the current iteration cycle, the vehicle controller generates at least two reference random numbers and sends each reference random number to the digital key control module. The digital key control module calculates each reference random number based on a pre-configured encryption algorithm or key to obtain a first reference response value corresponding to each reference random number. Simultaneously, the vehicle controller calculates each reference random number based on the same or a corresponding encryption algorithm or key as the digital key control module to obtain a second reference response value corresponding to each reference random number.

[0059] The vehicle controller performs a consistency comparison between each first reference response value and its corresponding second reference response value to obtain the comparison results for each reference random number. If a preset number of comparison results show consistency, the permission security check result for the current iteration cycle is considered passed. Based on the permission security check results for each iteration cycle, the permission security check result for the vehicle startup request is determined. Specifically, if the permission security check results for more than 90% of iteration cycles pass, the permission security check result for the vehicle startup request can be considered passed.

[0060] S130. If the security test result is passed, a digital key search request is generated and sent to the NFC module through the digital key control module. The NFC module interacts with the user terminal based on the digital key search request. After the digital key is found, a status check request is generated and sent to the digital key control module. The digital key control module performs a status check on the digital key based on the status check request, obtains the status check result, and sends the status check result to the vehicle controller.

[0061] If the vehicle controller verifies the security of the vehicle start request, it generates a digital key retrieval request; if the security of the vehicle start request fails, it generates a failure message and sends it to the user terminal.

[0062] The vehicle controller sends a digital key retrieval request to the NFC module via the digital key control module. Upon receiving the request, the NFC module parses it, identifies the user terminal, and interacts with the terminal to search for the existence of a digital key. If the corresponding digital key is found, it generates a status check request and sends it to the digital key control module. The digital key control module performs a status check on the digital key based on the status check request, obtains the status check result, and sends the result to the vehicle controller.

[0063] In one optional embodiment, the digital key control module performs a status check on the digital key based on a status check request and obtains a status check result, including: verifying the digital signature of the digital key based on a preset shared key according to the status check request to obtain a legality verification result; if the legality verification result passes, verifying the access permissions of the digital key to obtain an access permission verification result; if the access permission verification result passes, verifying the current status of the vehicle to obtain a status check result.

[0064] Upon receiving a status check request, the digital key control module can parse the request to obtain the digital key and verify its validity. Specifically, it can perform signature verification on the digital signature of the parsed digital key to determine its legality and obtain a validity verification result. If the validity verification passes, it will verify the access permissions of the digital key; if the validity verification fails, it will generate a failure message and send it to the user terminal.

[0065] Access control verification for digital keys can specifically include checking the expiration time of the digital key and verifying the identity of the user who owns the digital key. If the access control verification for the digital key passes, the status check result is "verification passed"; if the access control verification for the digital key fails, the status check result is "verification failed".

[0066] S140. Based on the status check results, control the vehicle to start.

[0067] The vehicle controller starts the vehicle when the status check result is passed.

[0068] In an optional embodiment, after sending the digital key retrieval request to the NFC module through the digital key control module, the method further includes: if no status check result is received from the digital key control module within a preset time period, then sending the digital key retrieval request to the NFC module again through the digital key control module; if the number of times the digital key retrieval request is sent to the NFC module reaches a preset number of times threshold, then generating a preset prompt message and sending the prompt message to the instrument display.

[0069] The preset time period and the threshold for the number of transmissions can be pre-set by relevant technical personnel. For example, the threshold for the number of transmissions can be 3.

[0070] If no status check result is received from the digital key control module within a preset number of transmissions, a preset prompt message is generated and sent to the instrument panel display. The prompt message could be, for example, "No valid key in the vehicle. Please restart within the NFC start area."

[0071] This invention's technical solution, upon detecting a vehicle start request initiated by a user terminal using NFC, generates a secure random number and sends it to the digital key control module. The digital key control module then generates and sends back a first response value based on this secure random number. Based on the secure random number and the first response value, it performs a security check on the vehicle start request. If the security check passes, it generates a digital key search request and sends it to the NFC module. After finding the digital key, the NFC module generates and sends a status check request to the digital key control module. The digital key control module then performs a status check on the digital key based on the status check request, obtains the status check result, and sends the result to the vehicle controller. Based on the status check result, it controls the vehicle to start. This technical solution improves the security of NFC key detection and vehicle start-up security by introducing a security detection method to detect vehicle start requests initiated using NFC. The NFC module only participates in data exchange; instead, the digital key control module performs status checks and other data authentication. This achieves logical adaptation and compatibility with multiple security protocols of digital keys, reducing the workload of mobile phone adaptation development.

[0072] Example 2

[0073] Figure 2 This is a flowchart of a vehicle starting method based on near-field communication provided in Embodiment 2 of the present invention. This embodiment is applicable to the case of starting a vehicle based on the vehicle's near-field communication (NFC) function. The method can be executed by a vehicle starting device based on near-field communication, which can be implemented in hardware and / or software. The vehicle starting device based on near-field communication can be configured in an electronic device, for example, in a digital key control module in a vehicle control system.

[0074] like Figure 2 As shown, this method is executed by the digital key control module in the vehicle control system, and includes:

[0075] S210. Obtain a secure random number generated by the vehicle controller when it detects a vehicle start request initiated by the user terminal based on the NFC function.

[0076] Users can initiate a vehicle start request via the NFC function provided on their user terminal, which can be a mobile phone or tablet. When the vehicle controller detects the vehicle start request, it performs a security verification. This security verification may include anti-theft security verification and access control security verification.

[0077] The vehicle-side controller randomly generates a secure random number and sends it to the digital key control module. The digital key control module calculates the secure random number based on a preset encryption algorithm or key, such as a hash algorithm, to obtain a first response value, and then feeds this first response value back to the vehicle-side controller. The encryption algorithm or key in the digital key control module can be pre-configured by relevant technical personnel. Specifically, it can be the same as the encryption algorithm or key in the vehicle-side controller, or it can be a symmetric encryption algorithm or key; this embodiment does not impose any restrictions on this.

[0078] S220. Based on a secure random number, generate and feed back a first response value to the vehicle controller, so that the vehicle controller can perform a security check on the vehicle start request based on the secure random number and the first response value, and generate and feed back a digital key search request when the security check result is passed.

[0079] The vehicle controller can compare the response value generated by the security random number with the response value fed back by the digital key control module, and then perform security verification on the vehicle start request based on the comparison result.

[0080] In one optional embodiment, a security check is performed on the vehicle startup request based on a secure random number and a first response value, including: generating a second response value based on the secure random number; performing an access security check on the vehicle startup request based on the first and second response values ​​to obtain an access security check result; obtaining user location information of the user terminal and vehicle location information of the vehicle itself; performing an anti-theft security check on the vehicle startup request based on the user location information and vehicle location information to obtain an anti-theft security check result; and performing a security check on the vehicle startup request based on the access security check result and the anti-theft security check result.

[0081] The vehicle controller uses the same or corresponding encryption algorithm or key deployed with the digital key control module to encrypt and calculate a secure random number, obtaining a second response value. The first and second response values ​​are compared for consistency. If they match, the security verification of the vehicle start request's permissions passes; otherwise, the security verification of the vehicle start request's permissions fails.

[0082] The system acquires the user's location information from the user terminal and the vehicle's location information. If the distance between the user's location and the vehicle's location is less than a preset distance threshold, the anti-theft security check for the vehicle startup request passes; if the distance between the user's location and the vehicle's location is not less than the preset distance threshold, the anti-theft security check for the vehicle startup request fails. The distance threshold can be preset by relevant technical personnel; for example, the distance threshold can be set to 2 meters.

[0083] If both the access security check and the anti-theft security check pass, the security check for the vehicle startup request passes; if either the access security check or the anti-theft security check fails, the security check for the vehicle startup request fails.

[0084] S230. Send the digital key search request to the NFC module so that the NFC module can interact with the user terminal based on the digital key search request, and generate and send back a status check request after the digital key is found.

[0085] If the vehicle controller verifies the security of the vehicle start request, it generates a digital key retrieval request; if the security of the vehicle start request fails, it generates a failure message and sends it to the user terminal.

[0086] The vehicle controller sends the digital key search request to the NFC module through the digital key control module. After receiving the digital key search request, the NFC module parses the request, identifies the user terminal, and interacts with the user terminal to search for the existence of the digital key. Once the corresponding digital key is found, the NFC module generates a status check request and sends the status check request to the digital key control module.

[0087] S240. Based on the status check request, perform a status check on the digital key, obtain the status check result, and send the status check result to the vehicle controller so that the vehicle controller can control the vehicle to start according to the status check result.

[0088] If the digital key control module determines that the status check result is passed, the vehicle controller will start the vehicle.

[0089] In one optional embodiment, a status check is performed on the digital key based on a status check request to obtain a status check result, including: according to the status check request, performing signature verification on the digital signature of the digital key based on a preset shared key to obtain a legality verification result; if the legality verification result passes, then performing permission verification on the access rights of the digital key to obtain a permission verification result; if the permission verification result passes, then performing status verification on the current status of the vehicle to obtain a status check result.

[0090] Upon receiving a status check request, the digital key control module can parse the request to obtain the digital key and verify its validity. Specifically, it can perform signature verification on the digital signature of the parsed digital key to determine its legality and obtain a validity verification result. If the validity verification passes, it will verify the access permissions of the digital key; if the validity verification fails, it will generate a failure message and send it to the user terminal.

[0091] Access control verification for digital keys can specifically include checking the expiration time of the digital key and verifying the identity of the user who owns the digital key. If the access control verification for the digital key passes, the status check result is "verification passed"; if the access control verification for the digital key fails, the status check result is "verification failed".

[0092] In another vehicle start-up scenario, when a user touches the NFC start area with their terminal device, the NFC receives the request signal from the user's terminal, generates a standard authentication request, and sends it to the digital key control module to execute the authentication process. The authentication process can specifically include verifying the identity and validity of the digital key, specifically checking whether the digital key is authorized to perform the currently requested operation, and checking the digital key's authorization information, such as access time windows and permissions for specific functions.

[0093] This embodiment's technical solution obtains a secure random number generated by the vehicle controller when it detects a vehicle start request initiated by a user terminal based on the NFC function. Based on this secure random number, a first response value is generated and fed back to the vehicle controller. The vehicle controller then uses the secure random number and the first response value to perform a security check on the vehicle start request. If the security check passes, a digital key retrieval request is generated and fed back. The digital key retrieval request is sent to the NFC module, allowing the NFC module to interact with the user terminal based on the request. After finding the digital key, the NFC module generates and feeds back a status check request. Based on the status check request, a status check is performed on the digital key, and the status check result is sent to the vehicle controller. The vehicle controller then controls the vehicle to start based on the status check result. This technical solution improves the security of NFC key detection and vehicle start-up by introducing a security detection method to detect vehicle start requests initiated based on the NFC function. The NFC module only participates in data exchange; the digital key control module performs status checks and other data authentication. This achieves logical adaptation and compatibility with multiple security protocols of digital keys, reducing the workload of mobile phone adaptation development.

Figure 3As shown, this device can be configured in the vehicle controller of a vehicle control system, specifically including: a safety random number generation module 301, a safety detection module 302, a request generation module 303, and a vehicle start control module 304. Among them,

[0096] The secure random number generation module 301 is used to generate a secure random number when a vehicle start request initiated by a user terminal based on the NFC function is detected, and send the secure random number to the digital key control module so that the digital key control module can generate and feed back a first response value based on the secure random number.

[0097] The safety detection module 302 is used to perform safety detection on the vehicle start request based on the safety random number and the first response value;

[0098] The request generation module 303 is used to generate a digital key retrieval request if the security detection result is passed, and send the digital key retrieval request to the NFC module through the digital key control module, so that the NFC module can interact with the user terminal based on the digital key retrieval request. After the digital key is found, the module generates and sends a status check request to the digital key control module, and the digital key control module performs a status check on the digital key based on the status check request, obtains the status check result, and sends the status check result to the vehicle controller.

[0099] The vehicle start control module 304 is used to control the vehicle to start based on the status check result.

[0100] This invention's technical solution, upon detecting a vehicle start request initiated by a user terminal using NFC, generates a secure random number and sends it to the digital key control module. The digital key control module then generates and sends back a first response value based on this secure random number. Based on the secure random number and the first response value, it performs a security check on the vehicle start request. If the security check passes, it generates a digital key search request and sends it to the NFC module. After finding the digital key, the NFC module generates and sends a status check request to the digital key control module. The digital key control module then performs a status check on the digital key based on the status check request, obtains the status check result, and sends the result to the vehicle controller. Based on the status check result, it controls the vehicle to start. This technical solution improves the security of NFC key detection and vehicle start-up security by introducing a security detection method to detect vehicle start requests initiated using NFC. The NFC module only participates in data exchange; instead, the digital key control module performs status checks and other data authentication. This achieves logical adaptation and compatibility with multiple security protocols of digital keys, reducing the workload of mobile phone adaptation development.

[0106] The security detection unit is used to perform security detection on the vehicle start request based on the permission security detection result and the anti-theft security detection result.

[0107] Optionally, the permission security result determination unit includes:

If the comparison results are inconsistent, at least two reference random numbers are generated in the current iteration cycle, and each reference random number is sent to the digital key control module so that the digital key control module can generate a first reference response value corresponding to each reference random number.

[0109] The second reference response value generation subunit is used to generate a second reference response value for each of the reference random numbers based on each of the reference random numbers.

[0110] The comparison subunit is used to compare each of the first reference response values ​​with the corresponding second reference response values ​​to obtain the comparison results of each of the reference random numbers in the current iteration period;

[0111] The permission security detection subunit is used to perform permission security detection on the vehicle start request based on the comparison results of the reference random numbers in each iteration period, and obtain the permission security detection result.

[0112] Optionally, the device further includes:

[0113] The retrieval request sending module is used to send the digital key retrieval request to the NFC module again through the digital key control module if the status check result sent by the digital key control module is not received within a preset time period after the digital key retrieval request is sent to the NFC module through the digital key control module.

[0114] The prompt message generation module is used to generate a preset prompt message and send the prompt message to the instrument display if the number of times the digital key search request is sent to the NFC module reaches a preset number of times threshold.

[0115] The vehicle starting device based on near-field communication provided in the embodiments of the present invention can execute the vehicle starting method based on near-field communication provided in any embodiment of the present invention, and has the corresponding functional modules and beneficial effects of the method execution.

[0120] The check request generation module 403 is used to send the digital key search request to the NFC module so that the NFC module can interact with the user terminal based on the digital key search request, and generate and feed back a status check request after the digital key is found.

[0121] The inspection result generation module 404 is used to perform a status check on the digital key based on the status check request, obtain a status check result, and send the status check result to the vehicle controller so that the vehicle controller can control the vehicle to start according to the status check result.

[0122] This embodiment's technical solution obtains a secure random number generated by the vehicle controller when it detects a vehicle start request initiated by a user terminal based on the NFC function.

The vehicle controller then uses the secure random number and the first response value to perform a security check on the vehicle start request.

Based on the status check request, a status check is performed on the digital key, and the status check result is sent to the vehicle controller. The vehicle controller then controls the vehicle to start based on the status check result.
