[0050] In order to make the objectives, features, and advantages of the present invention more obvious and understandable, the following provides a detailed description of the specific embodiments of the present invention in conjunction with the drawings. Several embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the disclosure of the present invention more thorough and comprehensive.

[0051] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs. The terms used in the description of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0052] Embodiment 1

[0053] Please refer to Figure 1 , the first embodiment of the present invention provides a method for binding a UWB digital key and a vehicle, and the method includes steps S10 - step S60:

[0054] Step S10, when binding with the vehicle via the UWB digital key, obtain the request data sent by the UWB digital key to a preset cloud server.

[0055] First of all, it should be noted that the UWB digital key is an intelligent diagnostic device such as a smart phone, a tablet computer, a smart watch, etc. It can function as a vehicle key through account binding, so that the vehicle can be controlled only by carrying a smart phone, etc.

[0056] In this embodiment, when the UWB digital key is first bound to the vehicle, such as when purchasing a new vehicle or a new smart phone, it is necessary to connect it to the vehicle before using the UWB digital key. When binding the UWB digital key to the vehicle, the request data sent by the UWB digital key to the preset cloud server will be obtained. The request data contains information such as the device ID of the UWB key.

[0057] Step S20, send the request data to the back-end server of the UWB digital key through the cloud server.

[0058] It should be noted that the back-end server of the UWB digital key, that is, the server of the UWB digital key provider, is mainly used to verify the security matters during the daily use of the UWB digital key, etc. In this embodiment, after the cloud server obtains the request data, it will send the request data to the back-end server of the UWB digital key through the cloud server, and the back-end server of the UWB digital key is used to verify whether the UWB digital key has been tampered with, etc., so as to ensure the security of the UWB digital key itself.

[0059] Step S30, according to the request data, send verification information to the UWB digital key through the cloud server, including an activation link to jump to the e-wallet, and at the same time generate an activation password and send it to the host factory server.

[0060] In this embodiment, the step of sending verification information to the UWB digital key through the cloud server according to the request data, including an activation link to jump to the e-wallet, and at the same time generate an activation password and send it to the host factory server, includes:

[0061] Extract the feature data in the request data through the cloud server according to the request data sent by the cloud server;

[0062] Generate verification information for verifying the UWB digital key through the cloud server according to the feature data, and the verification information contains an activation link allowing jumping to the e-wallet;

[0063] Generate an activation password randomly according to the feature data, and send the activation password to the OEM server;

[0064] Wherein, when the user clicks the activation link in the verification information, it will automatically jump to the verification interface of the preset e-wallet to verify the binding process of the UWB digital key and the vehicle through the verification mechanism of the e-wallet.

[0065] Specifically, the steps of generating an activation password randomly according to the feature data and sending the activation password to the OEM server include:

[0066] Divide the feature data to obtain multiple feature sub-data corresponding to the number of digits of the activation password, and perform character conversion on the feature sub-data;

[0067] Perform a hash operation on all the feature sub-data after character conversion to obtain multiple hash strings with equal character lengths;

[0068] Randomly select any character from each of the hash strings, and randomly mix the selected characters to form the activation password.

[0069] More specifically, the steps of randomly selecting any character from each of the hash strings and randomly mixing the selected characters to form the activation password include:

[0070] Randomly select at least one digit or letter in each of the hash strings;

[0071] Randomly mix the digits or letters selected from all the hash strings to form the activation password.

[0072] In this embodiment, after sending the request data to the background server of the UWB digital key through the cloud server, according to the request data, the cloud server will send verification information to the UWB digital key. The verification information is, for example, a short message that contains an activation link to jump to the e-wallet in the UWB digital key. When the user clicks the activation link, they can enter the binding process of the UWB digital key and the vehicle. At the same time, an activation password will also be randomly generated according to the request data and sent to the OEM server of the vehicle manufacturer.

[0073] Specifically, according to the request data sent by the cloud server, extract the feature data in the request data, such as device ID, device version and other information from the cloud server. Then, according to the feature data, generate the verification information for verifying the UWB digital key through the operation server. The verification information contains an activation link that allows jumping to the e-wallet, and an activation password is randomly generated according to the feature data. Finally, the activation password is sent to the OEM server.

[0074] Among them, in the process of randomly generating the activation password according to the feature data, the feature data will first be divided to obtain multiple feature sub-data corresponding to the number of digits of the activation password. For example, if the activation password is 10 characters, the feature data will be divided into 10 feature sub-data, and the feature sub-data will be subjected to character conversion to obtain a string containing numbers and / or symbols. Then, the hashing operation is performed on the feature sub-data after character conversion to output multiple hash strings with equal character lengths. The hash string is 16 bits and consists of numbers, letters, and symbols. Then, any character in each hash string is selected, and all the characters selected from the multiple hash strings are randomly mixed to obtain the activation password.

[0075] More specifically, when selecting characters in the hash string, for example, at least one number or letter can be selected in each hash string, and then the numbers or characters selected from all the hash strings are randomly mixed to form the final activation password.

[0076] For example, the constructed activation password is 1!2@3#4￥5%, and its character count is 10 bits, corresponding to the 10 pre-divided feature sub-data.

[0077] Step S40: Send the activation password through the host factory server for display through the in-vehicle unit on the vehicle.

[0078] Among them, the in-vehicle unit on the vehicle is, for example, on-board diagnostics, IVI instrument, etc.

[0079] Step S50: When jumping to the verification interface of the e-wallet through the activation link and entering the activation password, verify whether the currently entered activation password is consistent with the pre-generated activation password through the vehicle Bluetooth module.

[0080] Among them, when it is verified through the vehicle Bluetooth unit that the currently entered activation password is consistent with the pre-generated activation password, it means that the verification is passed, and the method shown in this embodiment enters step S60.

[0081] Step S60: Send the verification certificate and vehicle identification information to the UWB digital key to complete the binding of the UWB digital key and the vehicle.

[0082] In summary, when the method shown in this embodiment binds the UWB digital key to the vehicle, it can ensure the authentication security of the UWB digital key through unique activation links and activation passwords. Moreover, starting from the activation requirements sent by the APP of the UWB digital key, multiple cloud encryptions can be performed to ensure the data security from the APP to the vehicle TBOX module. In addition, the vehicle TBOX module authenticates with the vehicle gateway to ensure the security of cloud data to the vehicle interior. Therefore, the method shown in this embodiment ensures that only in-vehicle users can use the UWB digital key to complete the binding with the vehicle using the activation password, ensuring security.

[0083] In summary, compared with the prior art, the beneficial effects of adopting the method for binding the UWB digital key to the vehicle shown in this embodiment are as follows:

[0084] When using the method shown in this embodiment to bind the UWB digital key to the vehicle, the request data sent by the UWB digital key to the preset cloud server is obtained, and the request data is sent to the background server of the UWB digital key through the cloud server. According to the request data, the cloud server sends verification information to the UWB digital key, including the activation link to jump to the e-wallet, and at the same time generates an activation password and sends it to the host factory server. The activation password is sent through the host factory server for display through the in-vehicle unit on the vehicle. When jumping to the verification interface of the e-wallet through the activation link and entering the activation password, it is verified whether the currently entered activation password is consistent with the pre-generated activation password through the vehicle Bluetooth module. If so, a verification certificate and vehicle identification information are sent to the UWB digital key to complete the binding of the UWB digital key to the vehicle. Therefore, the method shown in this embodiment can effectively improve the security of binding the UWB digital key to the vehicle.
