Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

In practical application, a vehicle owner can use the vehicle through the digital key of the vehicle owner and can borrow the vehicle to a borrower for use, and at the moment, the vehicle also generates and stores the digital key for the borrower so that the borrower can use the vehicle. When the borrower returns the vehicle, the digital key of the borrower stored in the vehicle needs to be deleted. In the related art, the digital key of the borrower is deleted in such a manner that the terminal of the owner of the vehicle sends a deletion request to the server, and then the server sends a deletion instruction to the vehicle in response to the deletion request, so that the vehicle deletes the digital key of the borrower. However, the actual vehicle parking environment is often an environment with a poor or no network, such as an underground parking lot, and the like, and the vehicle often cannot receive the deletion instruction sent by the server, and cannot execute the operation of deleting the digital key of the borrower, so that the digital key of the borrower cannot be successfully deleted, and potential safety hazards exist.

In one scheme of the related art, a server polls a timed task to detect whether a vehicle is online (namely, the vehicle is accessed to the internet), and if the vehicle is online, a deletion instruction is sent to the vehicle. In another scheme, when the vehicle is online, the server sends a notification, and after receiving the notification, the server sends a deletion instruction to the vehicle, which is better than the former scheme and reduces the cost.

In order to solve the above technical problem, an embodiment of the present application provides a method for deleting a digital key. The following examples are given for the purpose of illustration.

Fig. 1 is a flowchart of an exemplary digital key deletion method provided in an embodiment of the present application. The digital key deleting method provided by this embodiment is applied to a terminal of a vehicle owner, and may be executed by the terminal or software and/or hardware therein, where the terminal is connected to a target vehicle of the vehicle owner through short-distance wireless communication, as shown in fig. 1, the digital key deleting method at least includes the following steps:

and step 101, sending a deleting instruction to the target vehicle so that the target vehicle responds to the deleting instruction, deleting the digital key of the target borrower stored in the target vehicle, and sending a deleting result to the terminal.

Wherein the target vehicle is a vehicle that currently requires deletion of the digital key. The target borrower is a borrower who lends the target vehicle.

The terminal has a short-distance wireless communication function, and can be a mobile terminal, such as a mobile phone, or a wearable device, such as a bracelet. The short-range wireless Communication may be, but is not limited to, bluetooth, Near Field Communication (NFC), and the like.

And 102, sending a deletion request to the server under the condition that the deletion result is successful and the Internet can be accessed, wherein the deletion request is used for deleting the digital key of the target borrower stored in the server.

In practical application, if a target vehicle is parked in an underground parking lot or other poor network or non-network environments, the internet cannot be normally accessed, a vehicle owner needs to get near the target vehicle to enable the terminal to establish short-distance wireless communication connection with the target vehicle, at the moment, the terminal is influenced by the environment and may not normally access the internet. The terminal may periodically detect whether it is able to access the internet. And after receiving a deletion request sent by the terminal, the server responds to the deletion request and deletes the digital key of the target borrower stored in the server. Here, the server may be a cloud server or a physical server.

According to the scheme, the terminal of the vehicle owner and the target vehicle are connected through short-distance wireless communication, short-distance communication can be achieved, based on the short-distance communication, the terminal can directly send a deleting instruction to the target vehicle, so that the target vehicle can delete the digital key of the target vehicle borrower stored in the target vehicle in time, and under the condition that the deleting is successful and the internet can be normally accessed, a deleting request is sent to the server, so that the server can delete the stored digital key of the target vehicle borrower, and therefore even if the target vehicle is in an environment with poor network or no network for a long time, the digital key of the target vehicle borrower can be completely deleted in time based on the short-distance communication between the terminal and the target vehicle, and therefore safety is improved.

In practical applications, the digital key of the target borrower generally has an authorization time limit, the target borrower can control the target vehicle through the digital key within the authorization time limit, and the digital key is invalid after the authorization time limit is exceeded.

Under the condition that the target borrower returns the target vehicle in advance, although the owner has recovered the target vehicle, the authorization time limit of the digital key is not yet reached, at the moment, the digital key of the borrower is still effective, and the digital key is actively deleted in time through the terminal, so that the situation that the target borrower drives the vehicle away again after the owner recovers the vehicle can be prevented. Based on this, the sending of the deletion instruction to the target vehicle may be sending the deletion instruction to the target vehicle within an authorized period.

Of course, after the digital key of the target borrower is invalid, the digital key of the target borrower can be deleted, so that the safety is further improved. Then, the above-mentioned sending of the deletion instruction to the target vehicle may be sending of the deletion instruction to the target vehicle after the authorization period is exceeded.

In an embodiment, the sending the deletion instruction to the target vehicle may include: and sending a deleting instruction to the target vehicle under the trigger of the deleting operation of the owner.

In practical application, when the target borrower returns the target vehicle, the target borrower usually actively informs the owner of the target vehicle, and when the owner of the target borrower returns the target vehicle, the owner of the target vehicle can actively delete the target vehicle at the terminal to trigger the target vehicle to delete the digital key of the target borrower. Therefore, the digital key of the target borrower can be deleted in time.

Illustratively, an operable interface may be displayed at the terminal, the operable interface including a delete control for performing a delete operation. When the owner wants to delete the digital key of the target borrower, a deletion operation (for example, a click operation) can be performed on the deletion control, and when the terminal detects the deletion operation, a deletion instruction is sent to the server.

In one embodiment, the sending of the deletion instruction to the target vehicle may include: and after the target vehicle is lent, sending a deleting instruction to the target vehicle when the connection is established with the target vehicle for the first time.

In practical application, after the target vehicle of the owner is lent, the owner keeps a long distance from the terminal of the owner, the short distance wireless communication connection cannot be established between the owner and the terminal of the owner, after the target vehicle is returned, if the owner is close to the target vehicle, the connection can be established between the owner and the target vehicle, that is, after the target vehicle is lent, once the connection can be established, the target vehicle is returned by the target borrower, and the digital key can be deleted. Therefore, after the target vehicle is lent, when the connection with the target vehicle is detected for the first time, the deleting instruction can be immediately and automatically sent to the target vehicle, so that the digital key can be automatically and timely deleted without manual operation of a vehicle owner, and the method is very convenient.

The connection established with the target vehicle for the first time may be established by the terminal under the trigger of a connection operation of the owner (for example, a connection operation when the owner drives the vehicle), or may be automatically established by the terminal. One way to automatically establish the first connection is illustrated below.

In one embodiment, before sending the deletion instruction to the target vehicle, the terminal-side digital key deletion method may further include: determining whether the target vehicle has lent; in the case that the target vehicle has been lent, periodically detecting a target device that can establish a connection; when the target equipment is detected, judging whether the target equipment is a target vehicle or not; in the case where the target apparatus is the target vehicle, the connection described above is established. Correspondingly, after the target vehicle is lent, when the connection with the target vehicle is established for the first time, a deletion instruction is sent to the target vehicle, and the specific implementation manner of the deletion instruction may include: and sending a deleting instruction to the target vehicle when the target device is the target vehicle and the connection is established.

In this embodiment, the target device capable of establishing the connection is automatically and periodically detected when it is determined that the target vehicle is lent, when the detected target device is the target vehicle, the vehicle returns, the connection is automatically established, the connection is the first connection after the target vehicle is lent, then, a deletion instruction is automatically sent to the target vehicle, and the target vehicle is triggered to delete the digital key of the borrower, so that the digital key is automatically and timely deleted to improve the safety, the owner does not need to manually operate at a terminal, and only needs to approach the vehicle or pass by the vehicle, which is very convenient.

When judging whether the target equipment is the target vehicle, specifically, the name of the target equipment can be obtained, whether the name of the target equipment is consistent with the name of the target vehicle of the owner of the vehicle stored locally is judged, and if so, the target equipment is determined to be the target vehicle.

In one embodiment, the determining whether the target vehicle has been lent may include: and determining whether the target vehicle is lent or not based on the local latest vehicle utilization record. In practical applications, the terminal locally stores the vehicle usage record of the target vehicle, including the vehicle usage record of the owner, the loan record of the target vehicle, and the like. If the target vehicle is borrowed, the latest user record is the record of the target vehicle lending, so that whether the target vehicle is borrowed or not can be accurately judged based on the latest local vehicle utilization record.

In one embodiment, before periodically detecting a target device that can establish a connection, the method for deleting a digital key on the terminal side may further include: based on the authorization deadline for the target borrower, a periodically detected start time is determined, the start time being earlier than the authorization deadline. Correspondingly, the specific implementation manner of periodically detecting the target device capable of establishing the connection may include: when the start time is reached, the target device starts to be detected periodically.

In practical application, for the condition that the vehicle is returned in advance, because the authorization period is not reached, if the digital key of the target borrower is not deleted, the digital key is still effective, in order to improve the safety, the digital key of the target borrower needs to be deleted in advance of the authorization period, namely, the starting time is earlier than the authorization period, so that the periodic detection can be started as early as possible, so that the target vehicle can be detected as soon as possible after the target vehicle is returned, the connection is established, and the digital key of the target borrower is deleted in time.

Further, since the periodic detection is started immediately after the loan of the vehicle, wasteful overhead increases, and therefore, in the present embodiment, the periodic detection is started after the start time is reached, and overhead can be reduced. Typically, the vehicle will return near the authorization deadline, so the start time may be near the authorization deadline to further reduce overhead. Also, the vehicle owner will typically approach the vehicle at customary usage times, such as in the morning, noon, and evening of the day, which can be used as a starting time to further reduce costs.

For example, determining the start time for the periodic detection based on the authorized duration for the subject borrower may include: determining a first time length between the lending moment and the authorization deadline; and calculating the product of the first time length and the preset proportion to obtain a second time length, taking the moment earlier than the second time length of the authorization deadline as candidate time, and taking the habitual vehicle using time closest to the candidate time as starting time. The specific time value of the habitual car using time can be set by the car owner or a default setting is adopted.

For example, habitual car hours may include 6:00, 12:00, 18: 00. The lending time is 2021 year 1 month 7 days 12:00, the authorization period is 2021 year 1 month 8 days 12:00, the first duration is 1 day, the preset proportion is 1/3, the second duration is 1/3 days, then the candidate time is 2021 year 1 month 8 days 4:00, the recent habitual vehicle using time is 6:00, and then regular detection is carried out by taking 2021 year 1 month 8 days 6:00 as the starting time.

The period interval in the periodic detection can be set according to actual conditions. Each cycle may be initiated for a predetermined time. For example, the test is started every 6 hours and continued for 30 to 60 minutes.

In one embodiment, when receiving the deletion result of the target vehicle, the terminal may further send a reminding message, where the reminding message is used for the vehicle owner to know whether the digital key is deleted in time.

In one embodiment, the method for deleting a digital key at a terminal side may further include: acquiring information of a digital key of a target borrower; generating a deleting instruction carrying the information of the digital key of the target borrower, so that the target vehicle deletes the digital key of the target borrower based on the information of the digital key of the target borrower carried in the deleting instruction; and/or generating a deletion request carrying the information of the digital key of the target borrower, so that the server deletes the digital key of the target borrower based on the information of the digital key of the target borrower carried in the deletion request.

In practical application, the information of the digital key of the target borrower is used for indicating the digital key which needs to be deleted. The information of the digital key of the target borrower may include at least one of: identification information of the target borrower, identification information of the digital key, an authorization period of the digital key, and the like.

The target vehicle can obtain the information of the digital key of the target borrower from the deletion instruction, and accurately search and delete the stored digital key of the target borrower based on the information of the digital key of the target borrower.

The server can obtain the information of the digital key of the target borrower from the deletion request, and accurately search and delete the stored digital key of the target borrower based on the information of the digital key of the target borrower.

In one embodiment, the information of the digital key of the target borrower is acquired, and the specific implementation manner of the information of the digital key of the target borrower can comprise the following steps: sending an inquiry instruction to the target vehicle so that the target vehicle inquires the stored information lists of all the digital keys and sends the information lists to the terminal; receiving a list of information from a target vehicle; and acquiring the information of the digital key of the target borrower from the information list.

In practical application, the digital key stored by the target vehicle is really used for vehicle control, so that the information of the digital key acquired from the target vehicle is more accurate. In this embodiment, the inquiry instruction is sent to the target vehicle, the information list of all the digital keys actually stored in the target vehicle at present is obtained in real time, and specific information of which digital keys and digital keys are present can be accurately known from the information list, so that the information of the digital keys of the target borrower can be accurately obtained from the information list.

In addition, the information of the digital key of the target borrower can be directly obtained from the information of the digital key locally stored in the terminal.

If the target vehicle is borrowed, the target borrower can be determined based on the latest vehicle usage record, and the information of the digital key of the target borrower is obtained.

In one embodiment, the sending of the deletion instruction to the target vehicle may include: and sending a deleting instruction to the target vehicle based on a preset encryption algorithm. And/or sending a query instruction to the target vehicle, wherein the specific implementation manner of the query instruction can include: and sending a query instruction to the target vehicle based on a preset encryption algorithm.

In practical application, the owner has the authority to delete and inquire the target vehicle. The safety between the terminal of the owner of the vehicle and the target vehicle can be guaranteed based on a preset encryption algorithm.

The preset encryption algorithm may be, but is not limited to, an RSA encryption algorithm. The RSA encryption algorithm is an asymmetric encryption algorithm that includes a pair of public and private keys that can decrypt each other. Correspondingly, based on the preset encryption algorithm, the query instruction is sent to the target vehicle, and the specific implementation manner may include:

and encrypting the query instruction through the public key of the target vehicle to obtain a first ciphertext, then signing the first ciphertext by using the private key of the owner, and sending the first ciphertext to the target vehicle. And after the target vehicle receives the first ciphertext sent by the terminal, decrypting the first ciphertext by using the private key of the target vehicle, verifying the signature by using the public key of the vehicle owner, after the decryption is successful and the signature verification is successful, confirming that the information list of the digital key has the authority to access, and sending the information list of all the digital keys on the target vehicle to the terminal.

Correspondingly, based on the preset encryption algorithm, the deletion instruction is sent to the target vehicle, and the specific implementation manner may include:

and encrypting the deletion instruction by the public key of the target vehicle to obtain a second ciphertext, signing the second ciphertext by the private key of the vehicle owner, and then sending the second ciphertext to the target vehicle. And after the target vehicle receives the second ciphertext, decrypting the second ciphertext through the private key of the target vehicle, verifying the signature by using the public key of the vehicle owner, and after the signature is successfully verified, responding to the deleting instruction by the target vehicle, executing deleting operation, and deleting the digital key stored in the target vehicle. And after the deletion is successful, sending a deletion result of successful deletion to the terminal.

The following describes a digital key deletion method provided in the embodiments of the present application in more detail by taking a bluetooth key as an example.

In the car networking system, the car networking system mainly comprises a host, a Telematics BOX (T-BOX), an Application program (APP) and a server. The host is mainly used for video entertainment in the vehicle and vehicle information display. The T-BOX is mainly used for communicating with a server or a terminal APP, and vehicle information display and control of the terminal APP are achieved.

Based on this, in the application scenario of this embodiment, the terminal of adoption is the cell-phone, and cell-phone APP can realize the bluetooth key function. The target vehicle is provided with a T-BOX. The server is a content Service Provider (TSP) cloud platform.

Among the correlation technique, cell-phone APP passes through bluetooth communication technology and vehicle bluetooth module communication, realizes the short distance communication of people with the vehicle for accomplish control functions such as door unblock, shutting, vehicle start, door window switch. The data communication among the mobile phone APP, the TSP cloud platform and the T-BOX uses an RSA encryption algorithm to ensure the security. And the car owner can borrow the car to friends or rent to renters and other lenders for use through the mobile phone APP, and the T-BOX grants the Bluetooth key to the lenders, and the lenders replace the mechanical key to control the car through the Bluetooth key. Bluetooth keys are typically stored in three places, respectively: T-BOX, TSP cloud platform, cell-phone APP. When the borrower returns the vehicle, for safety reasons, the vehicle usually deletes the bluetooth key granted to the borrower and stored in the T-BOX and the bluetooth key stored in the TSP cloud platform. The mobile phone APP is required to delete the key through the TSP cloud platform, the T-BOX of the vehicle is required to be on line in the original design, and the mobile phone APP issues an instruction through the TSP cloud platform service to delete the Bluetooth key in the T-BOX of the vehicle.

The above-mentioned flow restricts the vehicle T-BOX to be on-line, but the actual vehicle parking environment is often an environment such as an underground parking lot where the network environment is not good or no network. At this time, the deletion of the bluetooth key of the borrower is not successfully performed. Conventional solutions typically trigger the deletion of the borrower's bluetooth key by polling on a timed task, or waiting for a notification when the T-BOX of the vehicle has a network. This solution tends to fail relatively slowly. The scheme that this embodiment provided can directly delete the bluetooth key through the bluetooth and inform TSP cloud platform under the cell-phone APP has the condition of network, need not restrict the vehicle T-BOX and go on the line, so convenient and fast more.

The following explains the flow of this scheme:

the Bluetooth key stored by the TSP cloud platform is mainly convenient for inquiring and using the mobile phone APP, and the Bluetooth key stored on the T-BOX is mainly matched with the mobile phone APP and used for real vehicle control. Therefore, after the borrower returns the vehicle, the most safe scheme is to delete the key on the T-BOX, and ensure that the vehicle cannot be driven by the borrower again. And secondly, deleting keys stored on the TSP cloud platform so that all Bluetooth keys on the T-BOX can be synchronously and accurately displayed on the mobile phone APP.

As shown in fig. 2, in the presence of a network, a user logs in a mobile phone APP by using a vehicle owner account, that is, step one, the vehicle owner account logs in the mobile phone APP is executed. After logging in, the mobile phone APP keeps the login state of the owner for a period of time, such as 14 days.

And step two, the mobile phone APP and the T-BOX are established to be connected through Bluetooth after the car owner opens the mobile phone APP and the mobile phone APP is started.

Specifically, the mobile phone APP starts to use Bluetooth to connect with the T-BOX, a Bluetooth KEY (KEY) is input, Bluetooth connection is initiated with the T-BOX through a T-BOX Bluetooth name and the Bluetooth KEY, the T-BOX verifies the identity of a vehicle owner, after the T-BOX verifies the identity of the vehicle owner, the mobile phone APP is successfully connected with the T-BOX Bluetooth, an anti-replay random number is sent to the vehicle owner, and then the anti-replay random number is carried when the mobile phone APP of the vehicle owner communicates with the T-BOX, so that the safety of the Bluetooth KEY is guaranteed.

During the authentication, whether the Bluetooth KEY is correct or not can be judged, if not, the connection failure is prompted to retry, and if the connection is correct, the Bluetooth connection between the mobile phone APP and the T-BOX is successful.

And step three, the mobile phone APP sends a query instruction to the T-BOX.

Specifically, the mobile phone APP generates an inquiry instruction, the inquiry instruction carries an owner account Identity (ID), a mobile phone device number ID and a replay-preventing random number, the inquiry instruction is encrypted into a first ciphertext through a T-BOX public key, then the first ciphertext is signed by using a private key of the owner, and the first ciphertext is sent to the T-BOX through a Bluetooth protocol.

And step four, the T-BOX receives the inquiry command, inquires the information lists of all the Bluetooth keys stored on the T-BOX in response to the inquiry command, and sends the information lists of all the Bluetooth keys to the mobile phone APP.

Specifically, after the T-BOX receives a first ciphertext sent by the mobile phone APP, the first ciphertext is decrypted by using a private key of the T-BOX, if the decryption is unsuccessful, the command is determined to be wrong, the response is not performed, if the decryption is successful, the public key of the car owner is used for signature verification, if the signature verification is unsuccessful, the command is determined to be wrong, the response is not performed, if the signature verification is successful, the identified user is determined to be the car owner, the user has the authority to access the information list of the Bluetooth keys, the information lists of all the Bluetooth keys stored in the T-BOX are inquired in response to the inquiry command, and the information lists of all the Bluetooth keys are sent to the mobile phone APP.

And step five, the mobile phone APP receives and displays the information lists of all the Bluetooth keys.

The owner looks up the bluetooth key that needs to delete on cell-phone APP.

And step six, the mobile phone APP sends a deletion instruction to the T-BOX under the trigger of the deletion operation of the vehicle owner.

Specifically, an operable interface is displayed on the mobile phone APP, a user selects a Bluetooth key of a target user to be deleted (namely deletion operation) on the interface, the mobile phone APP generates a deletion instruction under the trigger of the deletion operation, the deletion instruction carries an owner account ID, a mobile phone device number ID, a replay-preventing random number and information of the Bluetooth key of the target user, the deletion instruction is encrypted into a second ciphertext through a T-BOX public key, the second ciphertext is signed through a private key of the user, and the second ciphertext is sent to the T-BOX through a Bluetooth protocol.

And step seven, the T-BOX receives the deletion instruction, responds to the deletion instruction, deletes the Bluetooth key of the target vehicle stored in the T-BOX, and sends the deletion result to the mobile phone APP.

Specifically, after the T-BOX receives a second ciphertext sent by the mobile phone APP, the second ciphertext is decrypted through a private key of the T-BOX, if the decryption is unsuccessful, the command is determined to be wrong, the response is not performed, if the decryption is successful, the public key of the owner is used for signature verification, if the signature verification is unsuccessful, the command is determined to be wrong, the response is not performed, if the signature verification is successful, the identified user is determined to be the owner, the T-BOX responds to a deleting command, and the Bluetooth key corresponding to the information of the Bluetooth key of the target person to be borrowed and stored in the T-BOX is deleted. And after the deletion is successful, returning a deletion result of successful deletion to the mobile phone APP.

And step eight, after acquiring the deletion result of successful deletion, the mobile phone APP sends a deletion request to the TSP cloud platform under the condition that the Internet can be accessed.

Specifically, after the mobile phone APP obtains a deletion result that deletion is successful, a local task is created, and whether the mobile phone can access the internet or not is detected by taking a preset time interval (for example, 5 minutes) as an interval frequency. And when the condition that the mobile phone can access the Internet is detected, sending a deletion request to the TSP cloud platform so as to call an Application Program Interface (API) to delete the Bluetooth key deleted on the T-BOX before. And finally, deleting the Bluetooth key of the target borrower by the TSP cloud platform.

Or, after the target vehicle is lent, when the connection between the mobile phone APP and the T-BOX of the target vehicle is established for the first time, the query instruction and the deletion instruction may be automatically sent to the T-BOX of the target vehicle to implement automatic deletion of the bluetooth key. If the connection is automatically established, the connection can be established by acquiring the pre-stored Bluetooth KEY.

Therefore, the problem that the target borrower's Bluetooth key is safely deleted in the scene of poor network or no network is solved, and the target borrower's Bluetooth key is still effective after the vehicle owner receives the vehicle and drives the vehicle away again is prevented.
