Detailed Description

The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.

In one scheme of the related technology, a server polls a timing task to detect whether a vehicle is on line (i.e. accesses the internet), if the vehicle is on line, a deleting instruction is sent to the vehicle, however, the number of vehicles is large, the on-line time of the vehicle is not fixed, the efficiency of using the timing task is low, the cost is high, and the effect is poor. In another scheme, when the vehicle is on line, the notification is sent to the server, after the notification is received by the server, the deleting instruction is sent to the vehicle, so that the effect is better than that of the former scheme, and the cost is reduced.

In order to solve the above technical problems, an embodiment of the present application provides a method for deleting a digital key. The following is a detailed description of examples.

Fig. 1 is a flowchart of an exemplary method for deleting a digital key according to an embodiment of the present application. The digital key deleting method provided in 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 with a target vehicle of the vehicle owner through short-distance wireless communication, as shown in fig. 1, and the digital key deleting method at least includes the following steps:

And step 101, transmitting 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 transmitting a deleting result to the terminal.

Wherein the target vehicle is a vehicle that currently needs to delete the digital key. The target borrower is a borrower borrowing 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, near Field Communication), and so forth.

And 102, sending a deletion request to a server when the deletion result is that the deletion 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 the target vehicle is parked in an environment with poor network or no network, such as an underground parking lot, the internet cannot be normally accessed, the vehicle owner needs to get near the target vehicle, so that the terminal and the target vehicle establish short-distance wireless communication connection, at this time, the terminal is affected by the environment, and the internet cannot be normally accessed, however, compared with the target vehicle, the terminal cannot be in the environment with poor network or no network, such as the underground parking lot, for a long time, because the terminal can move along with the vehicle owner, the terminal can quickly reach the environment with good network, can normally access the internet, and at this time, the deletion request can be sent to the server. The terminal may periodically detect whether it is capable of accessing the internet. After receiving the deletion request sent by the terminal, the server responds to the deletion request to delete 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 the 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, 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 deleting is successful and the Internet can be accessed normally, a deleting request is sent to the server, so that the server can delete the stored digital key of the target vehicle borrower, and 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 of the terminal and the target vehicle, and safety is improved.

In practical applications, the digital key of the target borrower generally has an authorized period, and in the authorized period, the target borrower can control the target vehicle through the digital key, and the digital key is invalid when the authorized period is exceeded.

Under the condition that the target vehicle borrower returns the target vehicle in advance, although the vehicle owner has retracted the target vehicle, the authorization period of the digital key is not yet reached, at this time, the digital key of the vehicle borrower is still effective, the digital key is actively deleted in time through the terminal, and the situation that the target vehicle borrower drives the vehicle again after the vehicle owner retracts the vehicle can be prevented. In this case, the deletion instruction may be transmitted to the target vehicle within the 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 deletion instruction may be sent to the target vehicle after the authorization period has elapsed.

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 triggering of the deleting operation of the vehicle owner.

In practical application, when the target borrower returns the target vehicle, the owner of the vehicle is usually informed actively, and the owner can actively delete the target vehicle by the terminal under the condition that the owner knows that the target borrower returns the target vehicle, and 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.

For example, 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 clicking 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 deleting instruction is sent to the target vehicle, and the specific implementation manner may include: and after the target vehicle is borrowed, when the connection is established with the target vehicle for the first time, sending a deleting instruction to the target vehicle.

In practical application, after the target vehicle of the vehicle owner is borrowed, the terminal of the vehicle owner always keeps a long distance from the terminal of the vehicle owner, the terminal of the vehicle owner can be connected with the target vehicle if the vehicle owner approaches the target vehicle after the target vehicle is returned, that is, after the target vehicle is borrowed, once the connection can be established, the target borrower can return the target vehicle, and the digital key can be deleted. Therefore, after the target vehicle is borrowed, when the connection with the target vehicle is detected to be established for the first time, a deleting instruction can be immediately and automatically sent to the target vehicle, so that the digital key is automatically and timely deleted, the digital key is not required to be deleted by an owner, and the method is very convenient.

The connection with the target vehicle for the first time can be established under the triggering of the connection operation of the vehicle owner (for example, the connection operation of the vehicle owner when using the vehicle), or can be automatically established by the terminal. The following illustrates one way of automatically establishing the first connection described above.

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 been borrowed; periodically detecting a target device which can establish a connection in the case that the target vehicle has been borrowed; when the target equipment is detected, judging whether the target equipment is a target vehicle or not; in the case where the target device is a target vehicle, the above connection is established. Correspondingly, after the target vehicle is borrowed, when the connection is established with the target vehicle for the first time, a deleting instruction is sent to the target vehicle, and the specific implementation manner of the method can comprise the following steps: 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, under the condition that it is determined that the target vehicle is borrowed, the target device capable of establishing the connection is automatically detected periodically, when the detected target device is the target vehicle, the vehicle is considered to be returned, the connection is automatically established, the connection is the first connection after the target vehicle is borrowed, then, a deletion instruction is automatically sent to the target vehicle to trigger the target vehicle to delete the digital key of the borrower, so that the automatic and timely deletion of the digital key is realized, the terminal operation of a vehicle owner is not required, and the vehicle owner is only required to approach the vehicle or pass the vicinity of the vehicle, thereby being very convenient.

When judging whether the target equipment is a 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 locally stored vehicle owner's target vehicle 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: based on the local latest usage record, it is determined whether the target vehicle has been borrowed. In practical application, the terminal locally stores vehicle records of the target vehicle, including vehicle records of the vehicle owner, records of borrowing of the target vehicle, and the like. If the target vehicle is borrowed, the latest user record is the record of the borrowed target vehicle, so that whether the target vehicle is borrowed or not can be accurately judged based on the local latest vehicle use record.

In one embodiment, before periodically detecting the target device capable of establishing the connection, the method for deleting the digital key at the terminal side may further include: based on the authorization deadline for the target borrower, a start time for the periodic detection is determined, the start time being earlier than the authorization deadline. Accordingly, the periodic detection of the target device that can establish the connection may include: when the start time is reached, periodic detection of the target device is started.

In practical application, for the situation that the vehicle is returned in advance, if the digital key of the target borrower is not deleted, the digital key is still effective, and in order to improve the safety, the digital key of the target borrower needs to be deleted in advance of the authorized period, that is, the starting time is earlier than the authorized period, so that the digital key can be detected periodically as early as possible, 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 timely.

Further, since the periodic detection starts immediately after the vehicle is lent, wasteful overhead increases, the periodic detection starts again after the start time is reached in the present embodiment, and the overhead can be reduced. Typically the vehicle will return close to the authorized period, so the start time may be close to the authorized period to further reduce overhead. Also, owners typically get close to the vehicle at habitual times of use, such as in the morning, noon and evening of the day, and may take habitual times of use as start times to further reduce overhead.

Illustratively, determining the start time of the periodic detection based on the authorized term for the target borrower may include: determining a first time length from the lending time to the authorized time limit; and calculating the product of the first time length and the preset proportion to obtain a second time length, taking the time earlier than the second time length of the authorized period as a candidate time, and taking the habitual train utilization time closest to the candidate time as a starting time. The specific time value of the habitual vehicle use time can be set by the vehicle owner or by default.

For example, habitual vehicle times may include 6:00, 12:00, 18:00. The borrowing time is 2021, 1, 7, 12:00, the authorized period is 2021, 1, 8, 12:00, the first time is 1, the preset proportion is 1/3, the second time is 1/3, the candidate time is 2021, 1, 8, 4:00, the latest habitual train time is 6:00, and 2021, 1, 8, 6:00 is taken as the starting time for periodic detection.

The periodic interval at the time of periodic detection may be set according to actual conditions. The detection may be continued for a preset time at the beginning of each cycle. For example, the detection is started every 6 hours, and the detection is continued for 30 to 60 minutes.

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

In one embodiment, the method for deleting a digital key on the 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 deleting 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 deleting request.

In practical applications, the information of the digital key of the target borrower is used for indicating the digital key to be deleted. The information of the digital key of the target borrower may include at least one of the following: the identity information of the target borrower, the identification information of the digital key, the authorized 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 deleting instruction, and accurately find the stored digital key of the target borrower and delete the digital key 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 deleting request, and accurately find the stored digital key of the target borrower and delete the digital key based on the information of the digital key of the target borrower.

In one embodiment, the method for obtaining the information of the digital key of the target borrower may include: sending a query instruction to the target vehicle so that the target vehicle queries the stored information list of all the digital keys and sends the information list 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 applications, the digital key stored in the target vehicle is actually used for vehicle control, so that the information of the digital key obtained from the target vehicle is more accurate. In this embodiment, by sending a query command to the target vehicle, an information list of all the digital keys actually stored by the target vehicle is obtained in real time, and from the information list, specific information of which digital keys and digital keys exist at present can be accurately known, so that 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 record, and the information of the digital key of the target borrower can be acquired.

In one embodiment, the deleting instruction is sent to the target vehicle, and the specific implementation manner may include: and sending a deleting instruction to the target vehicle based on a preset encryption algorithm. And/or, send a query instruction to the target vehicle, which may include: and sending a query instruction to the target vehicle based on a preset encryption algorithm.

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

The preset encryption algorithm may be, but 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 mutually decrypt. Correspondingly, based on a preset encryption algorithm, a query instruction is sent to the target vehicle, and the specific implementation manner may include:

and obtaining a first ciphertext through the public key encryption query instruction of the target vehicle, signing the first ciphertext by using the private key of the vehicle owner, and transmitting the first ciphertext to the target vehicle. After receiving the first ciphertext sent by the terminal, the target vehicle decrypts the first ciphertext by using the private key of the target vehicle, verifies the signature by using the public key of the vehicle owner, and confirms that the signature is authorized to access the information list of the digital key after the signature is successfully verified, and sends the information list of all the digital keys on the target vehicle to the terminal.

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

and obtaining a second ciphertext through the public key encryption deleting instruction of the target vehicle, signing the second ciphertext through the private key of the vehicle owner, and then sending the second ciphertext to the target vehicle. 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, the target vehicle responds to the deleting instruction to execute the deleting operation and delete the digital key stored on the target vehicle. And after the deletion is successful, sending a deletion result of the successful deletion to the terminal.

A method for deleting a digital key according to an embodiment of the present application will be described in more detail below by taking a bluetooth key as an example.

The internet of vehicles system mainly comprises a host computer, a remote information processor (T-BOX), a terminal Application (APP) and a server. The host is mainly used for video and audio entertainment in the vehicle and vehicle information display. The T-BOX is mainly used for communicating with a server or a terminal APP, and displaying and controlling vehicle information of the terminal APP is achieved.

Based on this, in the application scenario of this embodiment, the adopted terminal is a mobile phone, and the mobile 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, telematics Service Provider) cloud platform.

In the related art, a mobile phone APP is communicated with a vehicle Bluetooth module through a Bluetooth communication technology, so that short-distance communication between a person and a vehicle is realized, and control functions such as unlocking, locking, starting of the vehicle, opening and closing of the vehicle window and the like are completed. The data communication among the mobile phone APP, the TSP cloud platform and the T-BOX uses an RSA encryption algorithm to ensure safety. And the car owner can borrow the car to friends or rent to borrowers such as tenant through cell-phone APP and use, and T-BOX can grant bluetooth key for borrower this moment, borrower replaces mechanical key control vehicle through bluetooth key. Bluetooth keys are typically stored in three places, respectively: T-BOX, TSP cloud platform, cell-phone APP. When a borrower returns a vehicle, the vehicle typically mainly deletes the bluetooth key stored on the T-BOX and granted to the borrower, as well as the bluetooth key stored on the TSP cloud platform for safety. The mobile phone APP is required to delete keys through the TSP cloud platform, the original design requires the T-BOX of the vehicle to be online, and the mobile phone APP issues a command to delete Bluetooth keys in the T-BOX of the vehicle through the TSP cloud platform service.

The above-described flow restricts the vehicle T-BOX to be online, but the actual vehicle parking environment is often an environment where the network environment such as an underground parking garage is poor or no network exists. At this time, the deletion of the bluetooth key of the borrower is not successful. Conventional solutions typically trigger the deletion of a borrower's bluetooth key by timed task polling, or waiting for a network-time notification of the T-BOX of the vehicle. This approach tends to fail relatively slowly. According to the scheme provided by the embodiment, the Bluetooth key can be deleted directly through Bluetooth, and the TSP cloud platform is informed under the condition that the mobile phone APP has a network, so that the vehicle T-BOX is not required to be limited to be on line, and convenience and rapidness are achieved.

The flow of this scheme is described below:

the Bluetooth key stored by the TSP cloud platform is mainly convenient for inquiring and using of 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 safest scheme is to delete the key on the T-BOX, so that the vehicle is ensured not to be driven away again by the borrower. 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 case of a network, the user logs in the mobile phone APP using the owner account, that is, the step one is executed, and the owner account logs in the mobile phone APP. After logging in, the mobile phone APP can keep the logging-in state of the vehicle owner for a period of time, for example, the logging-in state is kept for 14 days.

And the owner opens the mobile phone APP, and after the mobile phone APP is started, the step two is executed, and Bluetooth connection is established between the mobile phone APP and the T-BOX.

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

During identity verification, whether the Bluetooth KEY is correct or not can be judged, if not, connection failure is prompted to try again, and if so, the mobile phone APP and the T-BOX Bluetooth are successfully connected.

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

Specifically, the mobile phone APP generates a query instruction, the query instruction carries an owner account number identification (ID, identity document), a mobile phone device number ID and an anti-replay random number, the query instruction is encrypted by a T-BOX public key to form a first ciphertext, then the first ciphertext is signed by the 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, and the information list of all the Bluetooth keys stored on the T-BOX is inquired in response to the inquiry command, and the information list of all the Bluetooth keys is sent to the mobile phone APP.

Specifically, after the T-BOX receives a first ciphertext sent by the mobile phone APP, decrypting the first ciphertext by using a private key of the T-BOX, if decryption is unsuccessful, determining that an instruction is wrong and not responding, if decryption is successful, performing signature verification by using a public key of a vehicle owner, if signature verification is unsuccessful, determining that the instruction is wrong and not responding, if signature verification is successful, determining that the identified user is the vehicle owner, having permission to access an information list of the Bluetooth keys, responding to a query instruction, querying the information list of all the Bluetooth keys stored on the T-BOX, and sending the information list of all the Bluetooth keys to the mobile phone APP.

And fifthly, the mobile phone APP receives and displays the information list of all the Bluetooth keys.

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

Step six, the mobile phone APP sends a deleting instruction to the T-BOX under the triggering of the deleting operation of the vehicle owner.

Specifically, an operable interface is displayed on a mobile phone APP, a vehicle owner selects a Bluetooth key of a target vehicle borrower to be deleted (namely a deleting operation) on the interface, the mobile phone APP generates a deleting instruction under the triggering of the deleting operation, the deleting instruction carries information of a vehicle owner account ID, a mobile phone equipment ID, an anti-replay random number and the Bluetooth key of the target vehicle borrower, the deleting instruction is encrypted through a T-BOX public key to form a second ciphertext, the second ciphertext is signed through a private key of the vehicle owner, and then the second ciphertext is sent to the T-BOX through a Bluetooth protocol.

And step seven, the T-BOX receives a deleting instruction, the Bluetooth key of the target vehicle stored in the T-BOX is deleted in response to the deleting instruction, and a deleting result is sent to the mobile phone APP.

Specifically, after the T-BOX receives the second ciphertext sent by the mobile phone APP, decrypting the second ciphertext through a private key of the T-BOX, if decryption is unsuccessful, determining that an instruction is wrong and not responding, if decryption is successful, performing signature verification by using a public key of a vehicle owner, if signature verification is unsuccessful, determining that the instruction is wrong and not responding, if signature verification is successful, determining that the identified user is the vehicle owner, and deleting a Bluetooth key corresponding to the information of the Bluetooth key of the target vehicle borrower stored on the T-BOX by the T-BOX in response to the deleting instruction. And after the deletion is successful, returning a deleting result of the successful deletion to the mobile phone APP.

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

Specifically, after the mobile phone APP acquires a deletion result of successful deletion, a local task is created, and whether the mobile phone can access the internet is detected by taking a preset time interval (for example, 5 minutes) as an interval frequency. When it is detected that the handset has access to the internet, a delete request is sent to the TSP cloud platform to invoke an application program interface (API, application Program Interface) to delete the bluetooth key previously deleted on the T-BOX. Finally, the TSP cloud platform deletes the bluetooth key of the target borrower.

Or, after the target vehicle is borrowed, when the mobile phone APP and the T-BOX of the target vehicle are first connected, an inquiry instruction and a deletion instruction are automatically sent to the T-BOX of the target vehicle, so as to realize automatic deletion of the bluetooth key. If the connection is automatically established, the connection may be established by acquiring a bluetooth KEY stored in advance.

Therefore, the problem that the Bluetooth key of the target borrower is still effective after the car owner receives the car is solved, and the target borrower drives the car again under the scene that the network is poor or no network.
