Detailed Description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

In a first aspect, an embodiment of the present disclosure provides a vehicle unlocking method, where the method is applied to a vehicle machine, and as shown in fig. 1, the method mainly includes:

101. and broadcasting the data packet.

The car machine in this embodiment is a vehicle-mounted terminal that is mounted on a vehicle cab, has multiple functions such as 3G/4G/5G wireless communication, GPS (Global Positioning System) navigation, shopping, entertainment, and audio and video, and can control operations such as unlocking and running of a vehicle. In the embodiment, the vehicle can interact with the mobile terminal, and the unlocking operation of the vehicle is completed under the request of the mobile terminal.

In practical application, the car machine broadcast is used for awakening the data packet of the vehicle unlocking application in a foreground running state or a background running state or in a closed state, and even if the vehicle unlocking application is not in the foreground running state, the data packet can be awakened in time, so that the mobile terminal and the car machine can perform vehicle unlocking related interaction. The vehicle is provided with a broadcasting module, and the vehicle machine broadcasts a data packet by using the broadcasting module. The method of broadcasting the data packet is related to the number of broadcasting modules deployed in the vehicle, and there are at least the following methods:

first, when a broadcast module is deployed in a vehicle, the car machine broadcasts a data packet for the mobile terminal to monitor by using the broadcast module. When the mobile terminal monitors the data packet, the vehicle unlocking application is awakened, and when the vehicle unlocking application initiates data communication, the mobile terminal performs interactive verification with the mobile terminal initiating the data communication. If the interactive verification with the mobile terminal does not pass, the vehicle machine controls the broadcasting module to stop broadcasting the data packet, and determines a new data packet again, and broadcasts the new data packet by using the determined broadcasting module again.

Second, when a plurality of broadcast modules are deployed in a vehicle, a data packet is broadcast using only one of the plurality of broadcast modules at a time. When the mobile terminal monitors the data packet, the vehicle unlocking application is awakened, and when the vehicle unlocking application initiates data communication, the mobile terminal performs interactive verification with the mobile terminal initiating the data communication. If the interactive verification with the mobile terminal does not pass, the vehicle machine controls the broadcasting module which currently executes the broadcasting to stop broadcasting the data packet, and reselects a new broadcasting module from the plurality of broadcasting modules to broadcast the data packet. In the method, a plurality of broadcasting modules can work alternately, so that the vehicle-mounted device and the mobile terminal can complete interactive verification smoothly. It should be noted that, in order to improve the security, after controlling the broadcast module currently executing the broadcast to stop broadcasting the data packet, before reselecting a new broadcast module from the plurality of broadcast modules to broadcast the data packet, it is further necessary to determine whether the total broadcast duration of the data packet exceeds a preset duration threshold, and if it is determined that the total broadcast duration of the data packet reaches the preset duration threshold, it indicates that the data packet is broadcast for a longer time, and the probability of being maliciously attacked and maliciously intercepted is higher, it is necessary to obtain the new data packet, and reselect a new broadcast module from the plurality of broadcast modules to broadcast the new data packet. After acquiring a new data packet, in order to reduce the occupied amount of the storage space in the car machine, the data packet with the total broadcast time length reaching the time length threshold value is cleared, and the car machine does not store the data packet any more.

In this embodiment, the broadcast module may broadcast the data packet in the long-distance transmission mode or the short-distance transmission mode, and ensure that data communication can be established between the mobile terminal and the vehicle terminal whether the mobile terminal is in a network-connected state or a network-free state, thereby completing the operation of unlocking the vehicle. The long-distance transmission mode comprises a wired network, a 2G/3G/4G/5G wireless network and the like. The short-distance transmission mode comprises Bluetooth, radio frequency and the like. Optionally, the broadcast module is an iBeacon module (a must ken module, and the following "must ken module" is all expressed as the "iBeacon module"), and the iBeacon module is a module equipped with a BLE (Bluetooth Low Energy) communication function, and broadcasts a specific data packet to its surroundings by using a BLE technology, so that the vehicle unlocking application receiving the data packet performs an awake state. Because the communication mode of the iBeacon module is Bluetooth, even if the vehicle machine and the mobile terminal are in a double-off-line state, the operation of unlocking the vehicle can be completed through Bluetooth interaction.

In practical applications, the content included in the data packet may be determined based on service requirements, and is not specifically limited in this embodiment. Optionally, when the broadcast module is an iBeacon module, the data packet is iBeacon information. The data packet comprises the following contents: UUID, Major, Minor, and Measured Power. Where UUID is a universally unique identifier is a 128-bit identifier specified as the ISO/IEC11578:1996 standard. Major and Minor are set by the iBeacon issuer themselves and are both 16-bit identifiers. For example, the car machine can write the area information in Major, and write the ID of the car machine in Minor, etc. Measured Power is the reference Received Signal Strength (RSSI) at a distance of 1m between the iBeacon module and the mobile terminal. The vehicle machine can calculate the distance between the iBeacon module and the mobile terminal according to the reference RSSI and the strength of the signal fed back by the mobile terminal.

The following description is provided by deploying two broadcast modules "iBeacon module" in the car machine: as shown in fig. 2, an iBeacon module 201 and an iBeacon module 202 are deployed in the car machine. And broadcasting the iBeacon information by only one iBeacon module in the 2 iBeacon modules at the same time. An iBeacon controller is deployed in each iBeacon module, and the iBeacon controller is responsible for controlling the iBeacon module to open or close broadcasting iBeacon information. When the iBeacon module is opened to carry out iBeacon information broadcasting, the iBeacon module broadcasts iBeacon information to be monitored by the mobile terminal. When the vehicle machine and the mobile terminal initiating data communication carry out interactive verification, the vehicle machine broadcasts information related to the interactive verification to carry out verification with the mobile terminal, and after the verification is passed, the vehicle machine executes vehicle unlocking operation.

102.

And A2, sending the first vehicle-side random number and a preset vehicle-machine public key to the mobile terminal.

In this embodiment, when the communication connection in the bluetooth mode is performed between the car machine and the mobile terminal, the first car-side random number and the preset car machine public key are sent to the mobile terminal based on the bluetooth mode.

Specifically, the process of verifying the verification information by using the car machine private key comprises the following steps: and decrypting the mobile terminal public key and the mobile terminal side random number encrypted by the vehicle machine public key by using the vehicle machine private key, and comparing the mobile terminal public key with a mobile terminal public key preset in the vehicle machine when the mobile terminal public key is obtained through decryption. When the consistency is obtained through comparison, the verification is passed; if the inconsistency is compared, the verification is not passed.

Specifically, the second vehicle-side random number generation method may include, but is not limited to, any one of a monte carlo method, generation of U (0,1) random numbers, generation of random numbers from U (0,1) to other probability distributions, and generation of normal random numbers. The second vehicle-side random number is a character string in which at least one of a number, a letter, and a symbol is combined, and has a predetermined number of characters. It should be noted that, in order to ensure the security of the mutual authentication between the car machine and the mobile terminal, the second car-side random number is generated for the data communication between the current car machine and the mobile terminal.

A5, sending the second vehicle-side random number encrypted by the mobile terminal public key to the mobile terminal.

Specifically, when receiving the second vehicle-side random number encrypted by the mobile terminal public key, the mobile terminal verifies the second vehicle-side random number encrypted by the mobile terminal public key, and obtains the second vehicle-side random number when the verification is passed, so that the mobile terminal generates the second interactive verification information by using the first vehicle-side random number, the second vehicle-side random number, and the mobile terminal-side random number.

In this embodiment, the method for generating the first interactive verification information based on the random number at the vehicle side and the random number at the mobile side at least includes the following two methods:

first, a car machine side random number and a mobile side random number are spliced to obtain first interactive verification information. It should be noted that the splicing order of the car-machine-side random number and the mobile-side random number may be determined based on the service requirement, for example, the car-machine-side random number may be located before the mobile-side random number or may be located after the mobile-side random number when splicing. In addition, when the vehicle-side random number includes the first vehicle-side random number and the second vehicle-side random number, the first vehicle-side random number and the second vehicle-side random number are spliced first (the first vehicle-side random number may be located before the second vehicle-side random number or may be located after the second vehicle-side random number in splicing), and then the spliced first vehicle-side random number and the spliced second vehicle-side random number are spliced with the mobile-side random number.

And secondly, performing preset operation on the random number at the vehicle side and the random number at the mobile side to obtain first interactive verification information. Wherein the predetermined operation at least comprises a hash operation.

Specifically, in order to be able to successfully verify the encrypted vehicle key information, the method of decrypting the data using the second mutual authentication information should correspond to the method of encrypting the data using the first mutual authentication information.

It should be noted that, the first mutual authentication information and the second mutual authentication information are both generated based on the car machine side random number and the mobile side random number of the current data communication, so that the transmission of the car key information between the car machine and the mobile terminal is completed based on the first mutual authentication information and the second mutual authentication information, and the security protection effect is excellent.

103. And determining the distance between the mobile terminal and the vehicle, and executing vehicle unlocking operation corresponding to the distance based on the vehicle key information.

In practical application, the car key information is composed of a plurality of characters, wherein the characters at least comprise at least one of the following contents: data, letters, and symbols. Illustratively, the vehicle key information is "123456 AAC".

In practical applications, the smaller the distance between the mobile terminal and the vehicle is, the closer the vehicle user holding the mobile terminal is to the vehicle is, the greater the user's control over the vehicle is, and therefore, the smaller the distance between the mobile terminal and the vehicle is, the higher the correlation between the performed vehicle unlocking operation and the vehicle entering the driving state is.

Illustratively, as shown in fig. 3, the vehicle periphery is at 30, 31, 32, and 33, respectively, representing four consecutive distance ranges, where 30 is the corresponding range of the vehicle interior space, i.e., 30 is actually the vehicle. When the distance between the vehicle and the mobile terminal is within the distance range of 33, the mobile terminal is far away from the vehicle, the vehicle does not execute the vehicle unlocking operation, and the vehicle continuously measures the real-time distance between the vehicle and the mobile terminal within the distance range of 33. When the distance between the vehicle and the mobile end is within the range of 32, the mobile end is closer to the vehicle, and at the moment, a user holding the mobile end has certain control force on the vehicle, so that the vehicle machine can unlock the vehicle door and meet the user to enter the vehicle. When the distance between the vehicle and the mobile terminal is within the range of 31, it is indicated that the mobile terminal is close to the vehicle, and at this time, a user holding the mobile terminal can enter the vehicle at any time. When the distance between the vehicle and the mobile terminal is within the range of 30, it is described that the user holding the mobile terminal has entered the vehicle, and the vehicle is convenient for the user to use the vehicle, at this time, the vehicle-mounted device unlocks the vehicle and enters a starting state, and the user can directly drive the vehicle.

Furthermore, in order to ensure the safety of the vehicle, after the distance between the mobile terminal and the vehicle is determined, whether a touch signal aiming at a target component of the vehicle is received or not can be detected, wherein the touch signal is generated when a user touches the target component; if the touch signal aiming at the vehicle target component is detected and received, it is indicated that the user with the mobile terminal has come near the vehicle, and the user can directly enter the vehicle when the vehicle is unlocked, so the vehicle-mounted device needs to execute the vehicle unlocking operation corresponding to the distance based on the vehicle key information. Alternatively, the target component may be a vehicle door.

In this embodiment, determining the distance between the mobile terminal and the vehicle may include: and determining the distance between the mobile terminal and the vehicle according to the data packet and a feedback signal fed back by the mobile terminal aiming at the data packet, which is acquired by a positioning auxiliary module deployed in the vehicle.

And acquiring a feedback signal fed back by the mobile terminal aiming at the data packet at the positioning auxiliary module, and determining the distance between the mobile terminal and the vehicle by the following formula (1).

S＝10^{((abs(RSSI)-A)/(10*n))} (1)

Wherein, the RSSI is the intensity of the feedback signal; a is the signal intensity when the broadcast module and the mobile terminal are separated by 1 meter; n is an environmental attenuation factor. It should be noted that the RSSI is the feedback signal strength, which is the average value of the strengths of the feedback signals received by the positioning assistance modules.

The following is illustrated by way of example in FIG. 4: the positioning assistance module includes: the positioning device comprises BLE positioning auxiliary modules arranged on two B columns which are symmetrical about the axis in the vehicle, a BLE positioning auxiliary module arranged on a central control of the vehicle and a BLE positioning auxiliary module arranged on a rear tail box. Each BLE positioning assistance module receives a feedback signal fed back by the mobile terminal for the data packet (a dashed line in fig. 4 is an acquisition path of the feedback signal). The LIN bus communication module is connected with each BLE positioning auxiliary module and used for summarizing feedback signals obtained by each BLE positioning auxiliary module.

According to the vehicle unlocking method provided by the embodiment of the disclosure, firstly, a data packet is broadcasted for a mobile terminal to monitor. When the mobile terminal monitors the data packet, the mobile terminal wakes up the vehicle unlocking application, carries out interactive verification with the mobile terminal initiating the data communication when the data communication is initiated by the vehicle unlocking application, and acquires the vehicle key information issued by the mobile terminal when the interactive verification is passed. Then, the distance between the mobile terminal and the vehicle is determined, and vehicle unlocking operation corresponding to the distance is performed based on the vehicle key information. Therefore, no matter the vehicle unlocking application is in a foreground state, a background state, a closed state or a no-network state, the vehicle unlocking application can be awakened through the broadcast data packet to initiate data communication to the vehicle machine, and therefore unlocking operation of the vehicle is completed.

Specifically, the method for generating the second interactive verification information by the mobile terminal at least includes the following two methods:

first, the random number at the mobile side and the random number at the vehicle side are spliced to obtain second interactive verification information. It should be noted that the splicing order of the mobile end random number and the car machine random number may be determined based on the service requirement, for example, the car machine random number may be located before the mobile end random number or located after the mobile end random number when splicing. In addition, when the vehicle-side random number includes the first vehicle-side random number and the second vehicle-side random number, the first vehicle-side random number and the second vehicle-side random number are spliced first (the first vehicle-side random number may be located before the second vehicle-side random number or after the second vehicle-side random number during splicing), and then the spliced first vehicle-side random number and the spliced second vehicle-side random number are spliced with the vehicle-side random number.

When the mobile terminal does not have the vehicle unlocking authority, the mobile terminal can apply the authority to the cloud terminal, acquire authorization information issued by the cloud terminal, and perform vehicle unlocking operation based on the authorization information. As shown in fig. 6, if the mobile terminal has no permission, the mobile terminal applies for permission to the cloud terminal to obtain authorization information issued by the cloud terminal, performs interactive verification with the car machine when the mobile terminal monitors a data packet, and issues car key data to the car machine for the car machine to perform car unlocking operation when the interactive verification passes.

In order to improve the security of data, the car key information is acquired from the cloud only when the mobile terminal needs to send the car key information to the car machine. And the mobile terminal can receive the car key information issued by the cloud terminal at least under the following two conditions:

the first method is to receive the car key information issued by the cloud at a preset frequency. The preset frequency is the frequency of using the vehicle by the user, so that the mobile terminal can receive the vehicle key information in time when the user uses the vehicle, and the vehicle can be unlocked in time according to the vehicle key information.

And secondly, the mobile terminal sends a vehicle key information acquisition request to the cloud terminal and receives vehicle key information aiming at the vehicle key information acquisition request sent by the cloud terminal.

When a vehicle driver has a vehicle unlocking demand, the mobile terminal can be triggered to send a vehicle key information acquisition request to the cloud terminal, so that the vehicle can be unlocked flexibly based on business demands in time according to the vehicle key information.

According to the vehicle unlocking method provided by the embodiment of the disclosure, when the mobile terminal monitors the data packet, the vehicle unlocking application is awakened, when the vehicle unlocking application initiates data communication, the vehicle unlocking application carries out interactive verification with the mobile terminal initiating the data communication, and when the interactive verification is passed, the vehicle key information is issued to the vehicle machine, so that the vehicle machine executes vehicle unlocking operation corresponding to the distance between the mobile terminal and the vehicle based on the vehicle key information. Therefore, no matter the vehicle unlocking application is in a foreground state, a background state, a closed state or a no-network state, the vehicle unlocking application can be awakened through the broadcast data packet to initiate data communication to the vehicle machine, and therefore unlocking operation of the vehicle is completed.

In a fourth aspect, an embodiment of the present disclosure provides a vehicle unlocking method, which is applied to a vehicle unlocking system including a vehicle machine and a mobile terminal, and vehicle unlocking is described below with reference to fig. 7:

when monitoring a data packet of a car machine broadcast, the mobile terminal initiates data communication to establish connection with the car machine, the car machine generates a first car-side random number by using a preset random number generation method, and executes step 501 to send the first car-side random number (denoted by random number a in fig. 7) and a car machine public key (denoted by SE _ pub in fig. 7) to the mobile terminal.

When the mobile terminal receives the random number A and the SE _ pub, executing a step 502 to verify the SE _ pub, wherein the verification process is to compare the SE _ pub preset by the mobile terminal with the received SE _ pub, and if the SE _ pub and the SE _ pub are different, the verification is not passed, and the interactive verification process is ended; if the two are the same, the check is passed, and step 503 is executed to generate a random number (indicated by a random number B in fig. 7) on the mobile terminal side. When generating the mobile side random number, step 504 is executed to send the mobile side public key Phone _ pub (indicated by Phone _ pub in fig. 7) and the mobile side random number to the car machine.

After receiving the mobile terminal public key Phone _ pub and the mobile terminal random number, the car machine executes step 505 to verify the mobile terminal public key. The process of verifying the mobile terminal public key may include, but is not limited to: comparing the mobile terminal public key with a mobile terminal public key preset in the vehicle machine; and when the comparison result is different, the result shows that the attack by a malicious party is possible in the transmission process, and the interactive verification process is ended. If the comparison is the same, the verification is passed. When the verification passes, step 506 is executed to generate a second vehicle-side random number (denoted by pre _ master _ key in fig. 7), and step 507 is executed to encrypt the pre _ master _ key using Phone _ pub and send the encrypted pre _ master _ key to the mobile terminal. And executing step 508 to generate first interactive verification information based on the first vehicle-side random number, the second vehicle-side random number and the mobile-side random number by adopting a preset interactive information generation method.

Optionally, the interaction information generation method may include, but is not limited to, a hash algorithm.

And when the mobile terminal receives the second vehicle-side random number encrypted by using the mobile terminal public key, the mobile terminal decrypts the second vehicle-side random number by using the mobile terminal private key to obtain the second vehicle-side random number. Then, step 509 is executed to generate second interactive verification information based on the first vehicle-side random number, the second vehicle-side random number, and the mobile-side random number by using a preset interactive information generation method.

When the mobile terminal generates the second interactive authentication information, step 510 is executed to encrypt the car key information by using the second interactive authentication information, and send the car key information to the car machine. And when the vehicle machine receives the vehicle key information encrypted by using the second interactive verification information, the vehicle machine uses the first interactive verification information for verification, and performs vehicle unlocking operation corresponding to the distance between the mobile terminal and the vehicle machine when the verification is passed.
