[0034] Currently, digital keys can be implemented using different digital key standards. Commonly used digital key standards include CCC (Car Connectivity Consortium), ICCE (Intelligent Car Connectivity Industry Ecosystem), ICCOA (Intelligent Car Connectivity Open Alliance), and proprietary standards developed by various manufacturers. However, these digital key standards are not unified, and different digital key standards cover different terminal and vehicle brands. This can lead to incompatibility issues when using the terminal's digital key function, impacting the user experience.

[0035] In view of this, embodiments of the present application provide a digital key application method, system, electronic device, and storage medium.

[0036] As shown in FIG1 , the digital key system of the present application includes a terminal, a vehicle and a server.

[0037] The server is used to send the protocol information of the vehicle's digital key protocol and the key information of the terminal's digital key to the terminal, and send the key information of the vehicle's digital key to the vehicle.

[0038] The terminal is used to determine the target digital key protocol among the multiple digital key protocols pre-integrated in the software development kit according to the protocol information of the vehicle's digital key protocol and the device information of the terminal, and interact with the vehicle based on the target digital key protocol and the key information of the terminal digital key.

[0039] The vehicle is used to interact with the terminal based on the protocol information of the vehicle's digital key protocol and the key information of the vehicle's digital key.

[0040] In an embodiment according to the present application, the protocol information of the digital key protocol of the vehicle refers to the protocol information of the digital key protocol used on the vehicle. The Software Development Kit (SDK) is used to realize the platformization of the key protocol, has the characteristics of plug-in, and can be quickly integrated into the terminal. Using the software development kit, multiple digital key protocols can be integrated into the terminal, and then the adapted digital key protocol can be selected based on the protocol information of the digital key protocol used by the vehicle and the device information of the terminal, so as to better be compatible with different terminal models and vehicle models and improve the user experience. At the same time, by using the software development kit to integrate multiple digital key protocols into the terminal, there is no need to design the compatibility of the digital key for the vehicle. After the vehicle receives the digital key, the digital key can be used by implementing the corresponding digital key protocol according to the original plan, which shortens the development cycle and reduces the design cost.

[0041] Optionally, the terminal's device information includes at least one of the terminal's brand, model, and implemented protocol. The protocol information for the digital key protocol includes the protocol name or type, such as CCC, and a general protocol or private protocol. General protocols include CCC, ICCE, ICCOA, and other protocols not developed by vehicle manufacturers. Private protocols refer to protocols developed by vehicle manufacturers. The digital key includes the terminal digital key and the vehicle digital key. The terminal digital key and the vehicle digital key are encrypted with certificates to ensure security, and the delivery channel undergoes two-way authentication to ensure channel security.

[0042] Optionally, the software development kit's functional upgrades can be performed via Over-the-Air Technology (OTA), eliminating the need to manually upgrade terminal applications and devices, which is more convenient.

[0043] Optionally, the server may be one or more, for example, a server for implementing digital key services, a server for maintaining multiple digital key protocols, and a server for providing digital key protocols, etc., or various digital key services may be integrated into one server.

[0044] The following is an introduction to the various modules of the system architecture of this application.

[0045] 1. Terminal

[0046] The terminal is equipped with a Digital Key application, which includes the Digital Key upper-layer business module, a platform-based key protocol SDK, and a Digital Key security unit. The Digital Key application is developed and architected separately from the SDK and business. This allows for independent business updates, either the business or the SDK, without impacting existing services. Upper-layer services are dynamically loaded.

[0047] The digital key upper-layer business module is mainly used to implement the UI (User Interface) functions of digital key creation and execution of digital key-related commands, including but not limited to digital key management, digital key issuance, and digital key near-field vehicle control commands.

[0048] The platform key protocol SDK (i.e. the software development kit) is used to integrate common digital key protocols on the market through the underlying library. Digital key protocols may include but are not limited to CCC, ICCE, ICCOA, and car manufacturer's private protocols. On the basis of integrating the digital key protocols, it is further integrated with the BLE 5.0 (Bluetooth Low Energy 5.0) official API (Application Programming Interface). The platform key protocol SDK can be configured to implement three functions: protocol identification, protocol judgment, and protocol determination.

[0049] Protocol identification may mean that the platform-based key protocol SDK receives and identifies the protocol information of the digital key protocol implemented by the current vehicle sent by the server.

[0050] Protocol judgment can mean that the platform key protocol SDK determines the matching protocol based on the digital key protocol implemented by the vehicle and the system, model and implemented protocol of the current terminal.

[0051] The protocol determination may indicate that the platformized key protocol SDK loads the matching protocol into the platformized key protocol SDK and instantiates it.

[0052] The digital key security unit is used to securely store and protect digital keys. The digital key security unit generates encrypted digital keys using encryption algorithms and lookup table technology.

[0053] 2. Server

[0054] The server may include a protocol maintenance module, a security service module, a tripartite protocol docking service module, and a platform protocol service module.

[0055] The protocol maintenance module is used to maintain the protocol types, distribution and management of different vehicle models.

[0056] Security service module, used for digital key security management and certificate management.

[0057] The tripartite agreement docking service module is used to connect with various servers of common protocols such as CCC, ICCE, ICCOA, and car manufacturer's private protocols.

[0058] The platform-based protocol service module is used for internal access to common protocols such as CCC, ICCE, and ICCOA, as well as vehicle manufacturer private protocol APIs.

[0059] 3. Vehicles

[0060] The vehicle can include a BLE module, a security chip, a communication module and a platform protocol service module.

[0061] The BLE module is a Bluetooth BLE chip module.

[0062] The security chip is a data security storage chip that can be used to ensure the security of digital keys and certificates.

[0063] Communication module, used to communicate with servers and terminals.

[0064] The platform-based protocol service module is used for hardware authentication and protocol access of common protocols such as CCC, ICCE, and ICCOA, as well as vehicle manufacturer-proprietary protocols.

[0065] This system utilizes a terminal SDK to integrate multiple digital key protocols, achieving platform-based digital key protocols. This system can select the appropriate digital key protocol based on the vehicle's digital key protocol information and the terminal's device information, providing greater compatibility with different terminal models and vehicle types, enhancing the user experience. Furthermore, there's no need to design digital key compatibility for the vehicle. Upon receiving the digital key, the vehicle simply implements the corresponding digital key protocol as originally planned, shortening the development cycle and reducing design costs.

[0066] The following introduces the method for implementing the above-mentioned digital key system.

[0067] Please refer to FIG2 , a method for applying a digital key, applied to a terminal, includes the following steps S1 to S3 .

[0068] In step S1, the protocol information of the vehicle's digital key protocol and the key information of the terminal's digital key are obtained.

[0069] In step S2, a target digital key protocol is determined from a plurality of digital key protocols pre-integrated in the software development kit according to the protocol information of the vehicle's digital key protocol and the device information of the terminal.

[0070] In step S3, the target digital key protocol and the key information of the terminal digital key are used to interact with the vehicle.

[0071] Optionally, the terminal application (the digital key application mentioned above) integrates multiple digital key protocols through the software development kit to realize the platformization of the digital key protocol. The software development kit forwards the key request to the upper-layer application, and the upper-layer application obtains the protocol information of the digital key protocol implemented by the vehicle bound to the user from the server through the cloud API interface, such as the protocol type. The server sends information related to the digital key and the protocol type of the digital key protocol used by the vehicle to the terminal application, and the terminal application sends this information to the software development kit. The software development kit binds the corresponding digital key protocol according to the protocol type of the digital key protocol used by the vehicle and the device information such as the terminal brand model. In this way, if the user switches the vehicle model, the server can re-send the corresponding digital key and protocol type to the terminal application according to the protocol type corresponding to the vehicle model switched by the user, and then bind the corresponding digital key protocol.

[0072] In this way, the functions of the digital key application can be upgraded through plug-in means, which includes but is not limited to, for example, adding a new digital key protocol to the digital key application, sending the library file corresponding to the new digital key protocol to the terminal through the server, and the digital key application adding the new digital key protocol to the digital key application through dynamic loading, and the user does not need to update the digital key application.

[0073] Optionally, the pre-integrated multiple digital key protocols include a universal protocol and a private protocol. Based on the protocol information of the vehicle's digital key protocol and the device information of the terminal, the target digital key protocol is determined among the multiple digital key protocols pre-integrated in the software development kit, including: determining whether there is a digital key protocol in the universal protocol that is adapted to the device information of the terminal and the protocol information of the vehicle's digital key protocol; if there is an adapted digital key protocol in the universal protocol, determining the adapted digital key protocol as the target digital key protocol; if there is no adapted digital key protocol in the universal protocol, determining the private protocol as the target digital key protocol, and / or sending a request to update the universal protocol.

[0074] In the embodiment of the present application, the universal protocol is a relatively mature and widely used protocol such as CCC, ICCE, and ICCOA. The adapted digital key protocol is first selected from the universal protocol to better ensure the terminal's performance and improve the user experience while adapting to the vehicle's protocol. When there is no adapted universal protocol, a request can be made to the server to obtain the universal protocol to update the universal protocol integrated in the terminal and then adapt again. If there is still no adapted universal protocol after the update, the car manufacturer's private protocol is determined to be the target digital key protocol, so that at least the use of the digital key can be guaranteed. Alternatively, when it is first determined that there is no adapted universal protocol, the car manufacturer's private protocol can be determined as the target digital key protocol. In actual implementation, when adapting the digital key, if it is first determined that there is no adapted universal protocol, it can be determined whether it is suitable to update the universal protocol in the terminal based on the terminal's network status, traffic status, etc. If it is suitable to update the universal protocol in the terminal, the universal protocol is updated and adaptation is restarted. If it is not suitable to update the universal protocol in the terminal, the car manufacturer's private protocol will be selected. When it is suitable to update the universal protocol, the user will be prompted whether to update the universal protocol to rebind a more suitable digital key protocol.

[0075] Optionally, multiple digital key protocols are integrated in the following ways: integrating interfaces corresponding to multiple digital key protocols according to the standards corresponding to the multiple digital key protocols to obtain an integrated interface; and implementing a preset wireless communication interface based on the integrated interface to achieve the integration of multiple digital key protocols.

[0076] In the embodiments of the present application, CCC, ICCE, ICCOA, and private protocols are all protocol standards implemented based on BLE5.0 low-power Bluetooth. CCC, ICCE, ICCOA, and private protocols can all implement the BLE5.0 interface based on the integration of corresponding interfaces through various protocol standards, thereby realizing a software development kit that integrates digital key protocols.

[0077] Optionally, the digital key application method further includes: in response to a preset instruction, performing at least one of adding a digital key protocol, deleting a digital key protocol, and updating a digital key protocol on the pre-integrated multiple digital key protocols.

[0078] Optionally, pre-set instructions can come from the server or user operations. Integrating multiple digital key protocols into the software development kit offers the advantage of plug-in functionality, allowing for more flexible and convenient addition, deletion, or update of digital key protocols. For example, unused digital key protocols can be deleted, new digital key protocols can be added / downloaded, and protocol information for digital key protocols can be updated.

[0079] Optionally, the digital key application method also includes at least one of the following: using a first security unit to encrypt the key information of the terminal digital key before interacting with the vehicle based on the target digital key protocol and the key information of the terminal digital key; and using a second security unit to store the key information.

[0080] In an embodiment of the present application, the first security unit and the second security unit may be encapsulated in the digital key security unit shown in FIG1 , or may be two independent units.

[0081] Optionally, after using the second security unit to store key information, the digital key application method also includes at least one of the following: when the terminal and / or vehicle is not connected to the Internet, interacting with the vehicle based on the target digital key protocol and the key information stored in the second security unit; performing identity authentication at intervals of a preset time, and determining that the key information stored in the second security unit is invalid if the identity authentication fails; performing identity authentication when using the digital key in an offline state, and determining that the key information stored in the second security unit is invalid if the identity authentication fails.

[0082] In an embodiment of the present application, after using the second security unit to store the key information, when the terminal and / or vehicle are not connected to the Internet, it is also possible to interact with the vehicle based on the target digital key protocol and the key information stored in the second security unit. The use of the digital key will not be affected in areas with poor signals such as garages or in the case of traffic restrictions.

[0083] After the second security unit stores the key information, identity verification is performed at preset intervals. If the identity verification fails, the key information stored in the second security unit is deemed invalid. In an embodiment of the present application, the identity verification can be one or a combination of fingerprint verification, face verification, and password verification, thereby ensuring the safety of the vehicle in the event of terminal loss.

[0084] Alternatively, when using a digital key without an internet connection, authentication is performed, and if authentication fails, the key information stored in the second security unit is deemed invalid. This approach allows verification using locally stored authentication information even when the server cannot monitor the security of the digital key, ensuring vehicle safety.

[0085] In actual implementation, when the terminal connects to the vehicle for key verification, it can determine whether the time interval since the last identity verification exceeds a preset time period. If so, identity verification is performed, and if the identity verification fails, the key information stored in the second security unit is determined to be invalid. Alternatively, a digital key information deletion function can be set in the vehicle. When identity verification information is entered on the vehicle and verification is passed, the relevant information on the vehicle used to verify the selected terminal digital key is deleted, thereby causing the terminal digital key verification to fail and achieving the purpose of invalidating the terminal digital key.

[0086] The interaction process between the terminal and the vehicle may include: Bluetooth connection, authentication, and communication.

[0087] Bluetooth connection: The terminal application connects to the vehicle via Bluetooth. To improve connection efficiency, the connection rules are as follows: the last four digits of the vehicle's VIN (Vehicle Identification Number) code are set to the last four digits of the vehicle's Bluetooth MAC (Media Access Control) address. When scanning, the terminal can quickly find the corresponding Bluetooth device through the last four digits of the vehicle's VIN code and establish a Bluetooth connection after finding the Bluetooth device.

[0088] Authentication: Authentication is performed after the Bluetooth connection is successful. Authentication is performed through the certificate transmitted by the terminal. If the certificate transmitted by the terminal is authenticated, subsequent services will continue. If the authentication fails, the current service will be terminated.

[0089] Communication: After authentication is passed, a secure interactive channel is successfully established, and digital key-related business operations can be performed, including but not limited to unlocking doors and closing doors without a network, opening / closing windows and the tailgate, etc.

[0090] As described above, the digital key application method of the embodiment of the present application is applied to the terminal, including the steps of: obtaining the protocol information of the vehicle's digital key protocol and the key information of the terminal's digital key; determining the target digital key protocol from the multiple digital key protocols pre-integrated in the software development kit based on the protocol information of the vehicle's digital key protocol and the terminal's device information; and interacting with the vehicle based on the target digital key protocol and the key information of the terminal's digital key. The technical solution of the present application utilizes a software development kit to integrate multiple digital key protocols in the terminal, and can select an adapted digital key protocol based on the protocol information of the digital key protocol used by the vehicle and the terminal's device information. Therefore, it is more compatible with different terminal models and vehicle types, and improves the user experience.

[0091] The present application also provides a digital key application method, which is applied to a server. The method includes the steps of: in response to a key acquisition request, sending the protocol information of the vehicle's digital key protocol and the key information of the terminal's digital key to the terminal, so that the terminal determines the target digital key protocol from the multiple digital key protocols pre-integrated in the software development kit based on the protocol information of the vehicle's digital key protocol and the terminal's device information, and interacts with the vehicle based on the target digital key protocol and the key information of the terminal's digital key.

[0092] In the embodiments of this application, the server integrates different digital key protocols and connects to different digital key protocol cloud services to achieve compatibility with different digital key protocols. Upon receiving a digital key request from a terminal, the server obtains the vehicle's corresponding protocol from the owner's bound vehicle and then issues a different digital key through the security service. The server also maintains data on the different protocols corresponding to different vehicle models.

[0093] Optionally, the method also includes: obtaining vehicle parameters of the vehicle; and sending key information of the vehicle digital key to the vehicle according to the vehicle parameters.

[0094] In an embodiment of the present application, after the vehicle receives the request from the server, it returns the vehicle parameters to the server. After the server receives the corresponding vehicle parameters, it sends the digital key of the corresponding vehicle parameters to the vehicle. After receiving the digital key, the vehicle stores the digital key in the vehicle safety chip and implements the corresponding digital key protocol as originally planned. There is no need for compatible adaptation, and the digital key protocols implemented by different vehicle models may be different.

[0095] Optionally, after sending the key information of the terminal digital key to the terminal and / or sending the key information of the vehicle digital key to the vehicle, the method also includes at least one of the following: sending the newly added digital key protocol and / or the updated digital key protocol to the terminal, so that the terminal performs at least one of adding a digital key protocol, deleting a digital key protocol, and updating a digital key protocol on the pre-integrated multiple digital key protocols; sending identity authentication instructions to the terminal and / or vehicle at intervals of a preset time, and when the identity authentication fails, determining that the key information associated with the terminal and / or vehicle is invalid.

[0096] In an embodiment of the present application, when a digital key protocol is updated or added, the newly added digital key protocol and / or the updated digital key protocol is sent to the terminal to continuously improve the user experience.

[0097] Authentication instructions are sent to the terminal and / or vehicle at intervals of a preset time, and when the authentication fails, the key information associated with the terminal and / or vehicle is determined to be invalid, thereby ensuring the safety of the vehicle when the terminal is lost. When the terminal and / or vehicle is not in an online state, the authentication instruction will fail to be sent. At this time, if it is determined that the network has not been connected for a period of time, the interval for sending the authentication instruction can be shortened to increase the success rate of sending (avoid missing the time to send the instruction when the network is briefly connected). Alternatively, when the network has not been connected for a period of time, when it is detected for the first time that the vehicle is connected to the network but the terminal is not connected to the network, an authentication instruction is sent to the vehicle, and the digital key deletion function is triggered when the verification passes. At this time, the user is allowed to delete the relevant information on the vehicle used to verify the selected terminal digital key, so that the terminal digital key verification fails, achieving the purpose of invalidating the terminal digital key.

[0098] As described above, the digital key application method of the embodiment of the present application is applied to the server and includes the following steps: in response to a key acquisition request, the protocol information of the vehicle's digital key protocol and the key information of the terminal's digital key are sent to the terminal, so that the terminal determines the target digital key protocol from the multiple digital key protocols pre-integrated in the software development kit based on the protocol information of the vehicle's digital key protocol and the terminal's device information, and interacts with the vehicle based on the target digital key protocol and the key information of the terminal's digital key. The technical solution of the present application utilizes a software development kit to integrate multiple digital key protocols in the terminal, and can select an adapted digital key protocol based on the protocol information of the digital key protocol used on the vehicle and the terminal's device information. Therefore, it is more compatible with different terminal models and vehicle types, and improves the user experience.
