[0034] The example embodiments will be described in detail below with reference to the accompanying drawings. In the following description, same numbers refer to same or similar elements throughout the drawings. The following example embodiments described in the detailed description are not meant to be all inclusive or to be the only embodiments that can be implemented in accordance with the present application. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present application as detailed in the appended claims.

[0035] The block diagrams in the drawings represent functional entities, which do not necessarily correspond to physically independent entities. That is, the functional entities can be implemented in software, in one or more hardware modules or integrated circuits, or in different network and / or processor devices and / or microcontroller devices.

[0036] The flowcharts shown in the drawings are merely illustrative, and do not necessarily include all contents and operations / steps, nor are they necessarily executed in the order described. For example, some operations / steps can be further divided, and some operations / steps can be combined or partially combined, so that the actual execution order can be changed according to the actual situation.

[0037] In the present application, "a plurality of" means two or more. The "and / or" describes the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B can represent the following three cases: A exists alone, A and B exist together, and B exists alone. The character " / " generally represents an "or" relationship between the associated objects before and after it.

[0038] The vehicle key has a function of storing historical login information, so that the vehicle key can be used to unlock / lock the vehicle quickly without re-authenticating the identity of the user of the vehicle key, and once the vehicle key is lost or stolen, the person who picks up or steals the vehicle key can easily unlock / lock the target vehicle, which has a greater security risk.

[0039] Therefore, an aspect of the present application provides a security management method of a vehicle key. For details, please refer to Figure 1 , Figure 1 FIG. 1 is a flow diagram of a security management method of a vehicle key according to an example embodiment of the present application. The security management method is applied to a target vehicle and includes at least S110 to S130, which are described in detail as follows:

[0040] S110: receiving a Bluetooth connection request carrying an identifier of a vehicle key.

[0041] The vehicle key can be a mobile device with a built-in vehicle unlocking / locking function application, and the vehicle key of the present application needs to have Bluetooth function and other wireless signal communication function. For example, mobile devices such as mobile phones, tablets, etc. can perform Bluetooth and other wireless communication with related vehicles, and can also use the cloud as a communication relay station to perform wireless communication with related vehicles.

[0042] The Bluetooth connection request includes but is not limited to port identifier, authentication information, request reply information type, etc. The port identifier is the initial port from which the Bluetooth connection request is sent, and the target vehicle can obtain the related data of the vehicle key according to the port. The port is the port for the vehicle key and the target vehicle key to perform Bluetooth data interaction; the authentication information includes the identifier of the request party (i.e. the identifier of the vehicle key), the authentication request time limit, the authentication method, etc.; the authentication request time length represents the time length from the time when the Bluetooth connection request is sent to the end time of the authentication window period, for example, the authentication request time length is 1 minute, and the time when the Bluetooth connection request is sent is 9:00, then the end time of the authentication window period opened by the vehicle key is 9:01, that is, only within the time period from 9:00 to 9:01, the Bluetooth authentication can be performed bidirectionally.

[0043] S120: if the identifier of the vehicle key matches the disabled device identifier successfully, a first disabled state code is generated according to the disabled device identifier, and the location information of the vehicle key is obtained; wherein the disabled device identifier is the device identifier set by the user on the cloud to prohibit the permission management of the target vehicle.

[0044] When the user finds that the vehicle key is lost or stolen, the user will log in to the cloud through other terminals to set the lost or stolen vehicle key as a disabled device, that is, the identifier of the vehicle key is set in the disabled device identifier list on the cloud, so that the disabled device identifier is sent to the vehicle key by the cloud.

[0045] The first disabling state code is generated by the target vehicle according to the disabling device identifier, which is a state code obtained by encrypting the disabling device identifier, to ensure the data security of the process of the target vehicle issuing the first disabling state code.

[0046] If the identifier of the vehicle key matches the disabling device identifier successfully, it indicates that the vehicle key has become a disabling device. The target vehicle generates a first disabling state code according to the corresponding disabling device identifier and a preset function, and actively acquires the location information of the vehicle key to send it to the new terminal bound by the user and to the cloud. The cloud triggers an alarm information to the new terminal bound by the user to provide a multi-path data transmission link to send the location information of the vehicle key to the new terminal bound by the user, facilitating the user to find the vehicle key.

[0047] In an embodiment, the generation method of the first disabling state code is exemplarily illustrated: the disabling device identifier is encrypted to obtain an encrypted string; the encryption operation includes but is not limited to standard encryption operation, asymmetric encryption operation, hash encryption operation, etc. The encryption operation can also be combined with a related key, for example, the disabling device identifier is encrypted according to a hash algorithm and a first key to obtain an encrypted string.

[0048] In order to ensure the security of data transmission and prevent related data leakage, the encrypted string is subjected to related confusion processing. In this embodiment, the character at the first preset position in the encrypted string is moved to the second preset position, and the numerical value corresponding to each character is added by a preset numerical value to obtain the first disabling state code. The first preset position and the second preset position represent different positions in the string; the preset numerical value can be a constant, and its numerical value can be adaptively adjusted according to the actual scene.

[0049] S130: Send the location information to the cloud, and generate a Bluetooth response information according to the first disabling state code and the data zeroing instruction, to make the vehicle key determine whether to execute the data zeroing instruction according to the matching result of the first disabling state code and the second disabling state code; the second disabling state code is a state code issued by the cloud to the vehicle key, the data zeroing instruction instructs to zero the historical cloud login information and historical Bluetooth login information stored in the vehicle key, and makes the vehicle key report its location information to the cloud.

[0050] The data clearing instruction is an instruction sent to the vehicle key when the vehicle key is identified as a disabled device. The instruction can be an instruction to be sent preset in the target vehicle, or it can be an associated instruction sent at the same time when the cloud sends the second disabled status code, that is, there is an associated mark between the second disabled status code and the data clearing instruction, so that the target vehicle can send the first disabled status code and quickly determine the data clearing instruction that needs to be sent to the disabled device based on the associated mark.

[0051] The Bluetooth response information may also include the target vehicle's Bluetooth port information, Bluetooth authentication information, etc. In certain embodiments, the target vehicle successfully establishes a Bluetooth connection with the disabled device via the Bluetooth response information, allowing the target vehicle to quickly obtain the disabled device's location information via the Bluetooth communication link. To ensure vehicle safety, the target vehicle does not grant all Bluetooth control permissions to the disabled device. For example, if the disabled device and the target vehicle successfully establish Bluetooth, the disabled device cannot unlock the target vehicle.

[0052] In certain embodiments, different conditions can be set to decentralizedly restrict the disabling device's management permissions on the target vehicle. For example, if a Bluetooth connection is successfully established between the disabling device and the target vehicle, the disabling device can unlock the target vehicle. Combined with onboard cameras and other devices, once a person carrying the disabling device enters the vehicle, the target vehicle automatically locks, disables all permissions on the disabling device, and reports captured image frames of the person to the cloud and / or the user terminal, allowing the user to identify the thief.

[0053] The target vehicle of the present application responds to the Bluetooth connection request of the vehicle key, determines whether the vehicle key is a disabled vehicle key based on the disabled device identifier received from the cloud, and generates a first disabled status code that is fed back to the vehicle key if it is determined to be a disabled vehicle key, so that the vehicle key executes the data clearing instruction returned by the target vehicle if it determines that the first disabled status code matches its locally stored second disabled status code successfully, so that the vehicle key clears the historical cloud login information and historical Bluetooth login information stored in itself to prevent the vehicle key from being used by others and the vehicle from being stolen. At the same time, the vehicle key sends its own location information to the cloud and the target vehicle to facilitate the user to retrieve the disabled vehicle key.

[0054] In order to retrieve the disabled device, it is necessary to strengthen the search for the disabled device. To this end, in another exemplary embodiment of the present application, a detailed description is given of how the target vehicle searches for the disabled device. For details, please refer to Figure 2 , Figure 2 is based on Figure 1 The exemplary embodiment shown is a flow chart of another method for managing vehicle key security. Figure 1Based on the S110 to S130 shown, at least S210 is also included, which is described in detail as follows:

[0055] S210: In response to a status signal sent by the cloud indicating that the disabled device is online, searching for a Bluetooth signal of the disabled device, and sending an alarm message to the cloud when the Bluetooth signal of the disabled device is found.

[0056] In this embodiment, the status signal is generated by the cloud when it detects a disabled device logging into the cloud or acquiring a wireless signal from the disabled device. This status signal indicates that the disabled device is online. The cloud sends this status signal to the target vehicle, triggering the target vehicle to actively search for the disabled device's Bluetooth signal. If the disabled device is within Bluetooth communication range of the target vehicle, the target vehicle will be able to detect its Bluetooth signal and send an alarm message to the cloud and / or the user terminal, alerting the user to the disabled device's proximity.

[0057] One aspect of this application provides another method for securely managing vehicle keys. Figure 3 , Figure 3 This is a flow chart of another vehicle key security management method according to an exemplary embodiment of the present application. This security management method is applied to vehicle keys and includes at least steps S310 to S330, which are described in detail as follows:

[0058] S310: Send a Bluetooth connection request carrying the vehicle key identifier to the target vehicle to receive Bluetooth response information returned by the target vehicle; wherein, the Bluetooth response information includes a first disabled status code and a data clear instruction, and the data clear instruction is an instruction generated by the target vehicle when it determines that the vehicle key identifier is a disabled device identifier.

[0059] The Bluetooth connection request includes but is not limited to port identification, authentication information, request response information type, etc. Among them, the port identification is the initial port for sending the Bluetooth connection request. The target vehicle can obtain the relevant data of the vehicle key based on this port. This port is the port for the vehicle key to exchange Bluetooth data with the target vehicle key; the authentication information includes the identification of the requesting party (i.e. the identification of the vehicle key), the authentication request time limit, the authentication method, etc.; the authentication request duration is the time from the time the Bluetooth connection request is sent to the end of the authentication window period. For example, if the authentication request duration is 1 minute and the Bluetooth connection request is sent at 9:00, then the end time of the authentication window period representing the opening of the vehicle key is 9:01, that is, two-way Bluetooth authentication can only be performed within the time period from 9:00 to 9:01.

[0060] The Bluetooth response information can further include Bluetooth port information of the target vehicle, Bluetooth authentication information, etc. The Bluetooth response information is information returned by the target vehicle to the vehicle key in response to the Bluetooth connection request. In some embodiments, the target vehicle successfully establishes a Bluetooth connection with the disabling device through the Bluetooth response information, so as to quickly obtain the location information of the disabling device through the Bluetooth communication link. In order to ensure the safety of the vehicle, the target vehicle does not open all Bluetooth control permissions to the disabling device. For example, the disabling device cannot perform an unlocking operation on the target vehicle in the case where the disabling device and the target vehicle successfully establish Bluetooth.

[0061] S320: Matching the first disabling state code with a second disabling state code issued by the cloud.

[0062] The second disabling state code is a state code generated by the cloud according to a disabling device identifier. The disabling device identifier is an identifier of a device set by a user on the cloud to prohibit the target vehicle from performing permission management. For example, the user sets the identifier of the vehicle key as the disabling device identifier on the cloud. The cloud then generates a second disabling state code corresponding to the disabling device identifier and issues it to the vehicle key.

[0063] In some embodiments, the vehicle key receives the second disabling state code and does not directly store it, but needs to decrypt and match the information. For example, the characters in the second preset position of the second disabling state code are moved to the first preset position, and the values of the characters are respectively subtracted by a preset value to obtain a value-converted second disabling state code; the value-converted second disabling state code is decrypted to obtain the disabling device identifier represented by the second disabling state code; and if the disabling device identifier is the same as the identifier of the vehicle key, the second disabling state code is stored. The first preset position and the second preset position represent different positions in the string; and the preset value can be a constant, and its value can be adaptively adjusted according to the actual scene.

[0064] If the disabling device identifier represented by the second disabling state code is different from the vehicle key, it indicates that the second disabling state code is incorrectly sent to the vehicle key by the cloud, and the vehicle key does not need to store it.

[0065] If the disabling device identifier represented by the second disabling state code is the same as the vehicle key, it indicates that the vehicle key has been set as a disabling device. In order to avoid incorrect settings, the vehicle key does not directly perform operations such as data clearing, but stores the second disabling state code, so as to match the first disabling state code sent by the target vehicle in the case where the second disabling state code is received, and determine whether to execute the data clearing instruction issued by the target vehicle according to the matching result.

[0066] S330: If the matching is successful, the historical cloud login information and the historical Bluetooth login information are cleared, and the self position information is sent to the cloud and the target vehicle; wherein the historical cloud login information is historical verification information for logging into the cloud, and the historical Bluetooth login information is historical verification information for starting the Bluetooth function.

[0067] If the matching is successful, it is indicated that the cloud and the target vehicle have both set the vehicle key to be a disabled device, the vehicle key clears the locally stored historical cloud login information and the historical Bluetooth login information to avoid others from stealing the vehicle key to unlock / lock the target vehicle, thereby improving the vehicle security; and the self position information is sent to the cloud and the target vehicle, so that the user can quickly know the position of the vehicle key through the target vehicle and the cloud account, thereby facilitating the recovery of the vehicle key.

[0068] In the case where the vehicle key determines that it has become a disabled vehicle key, the second disabled state code issued by the cloud is stored; if the second disabled state code matches the first disabled state code sent by the target vehicle, the vehicle key executes the data clearing instruction sent by the target vehicle to clear the historical cloud login information and the historical Bluetooth login information stored by the vehicle key, and sends the self position information to the cloud and the target vehicle, so as to facilitate the user to recover the disabled vehicle key.

[0069] One aspect of the present application provides another security management method of a vehicle key. For details, please refer to Figure 4 , Figure 4 is a flowchart of another security management method of a vehicle key according to an example embodiment of the present application. The security management method is applied to the cloud, and at least includes S410 to S420, which are described in detail as follows:

[0070] S410: In response to the user's changed cloud login information, the identification of the historical vehicle key corresponding to the changed cloud login information is updated to a disabled device identification, and a second disabled state code is generated according to the disabled device identification; wherein the historical vehicle key is a vehicle key specified in the historical cloud login information.

[0071] The user's changed cloud login information is information that the user successfully logs into the cloud server through a new mobile device. The cloud login information not only includes the identification of the historical vehicle key, but also includes the device identification of the new mobile device, the wireless communication port corresponding to the cloud server, the user's identity information, etc. The historical vehicle key can be a lost, stolen, or invalid vehicle key, i.e., the user expects to limit its control authority over the target vehicle.

[0072] The cloud end encrypts the disabled device identifier to obtain an encrypted string; moves a character at a first preset position in the encrypted string to a second preset position, and adds a preset value to the numerical value of each character respectively to obtain a second disabled state code. The first preset position and the second preset position represent different positions in the string; the preset value can be a constant, and its numerical value can be adaptively adjusted according to the actual scene.

[0073] S420: The second disabled state code is sent to the historical vehicle key, and the disabled device identifier is sent to the target vehicle corresponding to the historical vehicle key, so that the target vehicle returns Bluetooth response information including a data clearing instruction and the first disabled state code to the historical vehicle key in the case that the historical vehicle key sends a Bluetooth connection request, so that the historical vehicle key determines whether to execute the data clearing instruction according to the matching result of the first disabled state code and the second disabled state code; the data clearing instruction instructs to clear the historical cloud login information and the historical Bluetooth login information stored in the historical vehicle key, and makes the historical vehicle key report its own position information to the cloud end.

[0074] The cloud end sends different data to the target vehicle and the historical vehicle key. The cloud end sends the second disabled state code to the historical vehicle key, so that the historical vehicle key decrypts the second disabled state to obtain the disabled device identifier. If the disabled device identifier is the same as the identifier of the historical vehicle key itself, the second disabled state code is stored, which is used for the historical vehicle key to determine whether to execute the data clearing instruction according to the matching result of the two disabled state codes in the case that the historical vehicle key receives the first disabled state code sent by the target vehicle.

[0075] The cloud end also sends the disabled device identifier to the target vehicle, so that the target vehicle knows the disabled device in time. In the process of Bluetooth connection or other communication connection between the disabled device and the target vehicle, the target vehicle can quickly determine its disabled identity to limit the control authority of the disabled device.

[0076] The cloud end of the present application sends the disabled device identifier corresponding to the vehicle key to the target vehicle, so that the target vehicle knows the disabled vehicle key in time. The cloud end also sends the second disabled state code representing the disabled device identifier to the vehicle key, so that the vehicle key determines whether it has become a disabled vehicle key according to the second disabled state code.

[0077] The vehicle key can also send an unlocking request to the cloud end for the target vehicle to remotely unlock the vehicle. For example, in the case that the Bluetooth communication signal is not good, a parallel unlocking method is provided. The disabled device can also use this unlocking method. If the disabled device is allowed to remotely unlock the vehicle, the security of the vehicle will be reduced.

[0078] To this end, in another example embodiment of the present application, it is described in detail how the cloud prompts the target vehicle in the case of disabling the device online, please refer to Figure 5 , Figure 5 is based on Figure 4 The flowchart of another security management method of the vehicle key is shown in the example embodiment. The security management method further includes S510-S520 based on S410-S420 as shown in Figure 4 The details are as follows:

[0079] S510: In response to the unlocking request, determine the unlocking object to which the unlocking request is directed, and the identity of the requestor carried in the unlocking request.

[0080] The cloud receives any unlocking request, which represents an unlocking object (i.e. the target vehicle to be unlocked) and an unlocking requestor (i.e. the sender of the unlocking request). The unlocking request generally carries the identity of the unlocking object and the identity of the unlocking requestor, i.e. the identity of the target vehicle and the identity of the vehicle key.

[0081] S520: If the unlocking object is the target vehicle and the identity of the requestor is the identity of the disabled device, obtain the location information of the requestor and send a status signal representing that the requestor is online to the target vehicle.

[0082] Because the cloud can preset multiple vehicle-paired vehicle keys, it is necessary to determine the unlocking object and the requestor according to the relevant information in the unlocking request. If the historical vehicle key of the target vehicle has been set by the user as a disabled device, i.e. the identity of the historical vehicle key is set as the identity of the disabled device. If the cloud detects that the unlocking object is the target vehicle and the identity of the requestor is the identity of the disabled device, it means that the disabled historical vehicle key has interacted with the cloud, and someone is using the disabled historical vehicle key, so that the disabled historical vehicle key is in an online state. Therefore, the cloud sends a status signal representing that the disabled historical vehicle key is online to the target vehicle and / or the user terminal, so that the user knows the activity status of the disabled historical vehicle key, in order to patrol the historical vehicle key.

[0083] In another example embodiment of the present application, the application scenarios of the above-mentioned security management methods are exemplarily described, please refer to Figure 6 , Figure 6 is a schematic diagram of the application scenario of the security management method of the vehicle key of the present application. It includes a vehicle key 100, a target vehicle 200 and a cloud 300, which can be connected through wireless communication. The present application does not limit the connection mode between them.

[0084] The vehicle key 100 can be an application program loaded in a mobile device, which can be a mobile phone, a tablet, a mobile computer, etc. with Bluetooth communication function. The T-Box in the target vehicle 200 can be an actual executor of data receiving, processing and sending. The server in the cloud 300 can receive data sent by the vehicle key 100 and the target vehicle 200, and can also send relevant data to the vehicle key 100 and the target vehicle 200. The server can be a cloud server providing cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, CDN (Content Delivery Network), and big data and artificial intelligence platforms, etc. basic cloud computing services, which are not limited herein.

[0085] The cloud 300 updates the identifier of the historical vehicle key corresponding to the changed cloud login information to the disabled device identifier in response to the changed cloud login information of the user, and generates a second disabled state code according to the disabled device identifier; wherein the historical vehicle key is the vehicle key 100 specified in the historical cloud login information; the second disabled state code is sent to the historical vehicle key (i.e. the vehicle key 100), and the disabled device identifier is sent to the target vehicle 200 corresponding to the historical vehicle key. The vehicle key 100 receives the second disabled state code and decodes it to obtain the disabled device identifier, and matches it with its own identifier. If the matching is successful, the second disabled state code is stored; if the matching fails, the second disabled state code is cleared.

[0086] The vehicle key 100 sends a Bluetooth connection request carrying the identifier of the vehicle key 100 to the target vehicle 200. The target vehicle 200 receives the Bluetooth connection request, and if the identifier of the vehicle key 100 matches the disabled device identifier successfully, the target vehicle 200 generates a first disabled state code according to the disabled device identifier and obtains the location information of the vehicle key 100 to send to the cloud 300; the target vehicle 200 generates Bluetooth response information responding to the Bluetooth connection request according to the first disabled state code and the data zeroing instruction.

[0087] The vehicle key 100 receives the Bluetooth response information and determines whether to execute the data zeroing instruction according to the matching result of the first disabled state code and the stored second disabled state code; wherein the data zeroing instruction instructs to clear the historical cloud login information and the historical Bluetooth login information stored in the vehicle key 100, and makes the vehicle key 100 report its own location information to the cloud 300.

[0088] The application can improve the security management capability among the cloud, the vehicle key, and the target vehicle. The cloud sends a disabled device identifier corresponding to the vehicle key to the target vehicle, so that the target vehicle can learn the disabled vehicle key in time. The cloud also sends a second disabled state code representing the disabled device identifier to the vehicle key, so that the vehicle key determines whether it has become a disabled vehicle key according to the second disabled state code.

[0089] The vehicle key stores the second disabled state code sent by the cloud if it determines that it has become a disabled vehicle key. If the second disabled state code matches the first disabled state code sent by the target vehicle successfully, the vehicle key executes the data clearing instruction sent by the target vehicle, clears the historical cloud login information and the historical Bluetooth login information stored by the vehicle key, and sends the location information of the vehicle key to the cloud and the target vehicle, so that the user can find the disabled vehicle key.

[0090] In the process of responding to the Bluetooth connection request of the vehicle key, if the target vehicle determines that the vehicle key is a disabled vehicle key, it generates a first disabled state code according to the disabled device identifier and returns the first disabled state code and a data clearing instruction to the vehicle key as Bluetooth response information, so that the vehicle key determines whether to execute the data clearing instruction according to the matching result of the first disabled state code and the second disabled state code stored by the vehicle key.

[0107] The decryption module decrypts the numerical conversion second disabled state code to obtain the disabled device identifier represented by the second disabled state code;

[0108] The storage module stores the second disabled state code if the disabled device identifier is the same as the identifier of the vehicle key.

[0109] Another aspect of the present application also provides another kind of security management device of vehicle key, as shown in Figure 9 Figure 9 FIG. 1 is a structural schematic diagram of another kind of security management device of vehicle key according to an example embodiment of the present application. The security management device 900 is applied to the cloud, and includes:

[0110] The login response module 910 updates the identifier of the historical vehicle key corresponding to the changed cloud login information to the disabled device identifier in response to the changed cloud login information of the user, and generates a second disabled state code according to the disabled device identifier; wherein the historical vehicle key is the vehicle key specified in the historical cloud login information;

[0111] The delivery module 930 delivers the second disabled state code to the historical vehicle key, and delivers the disabled device identifier to the target vehicle corresponding to the historical vehicle key, so that the target vehicle returns the Bluetooth response information including the data zeroing instruction and the first disabled state code to the historical vehicle key in the case that the target vehicle receives the Bluetooth connection request sent by the historical vehicle key, so that the historical vehicle key determines whether to execute the data zeroing instruction according to the matching result of the first disabled state code and the second disabled state code; the data zeroing instruction instructs to perform zeroing processing on the historical cloud login information and the historical Bluetooth login information stored in the historical vehicle key, and makes the historical vehicle key report the own position information to the cloud.

[0112] In another example embodiment of the present application, the security management device 900 further includes:

[0114] The position information acquisition module acquires the position information of the requestor and sends the state signal representing that the requestor is online to the target vehicle if the unlock object is the target vehicle and the identifier of the requestor is the disabled device identifier.

[0115] ​The application improves the security management capability among the cloud, the vehicle key, and the target vehicle. The cloud sends a disabled device identifier corresponding to the vehicle key to the target vehicle, so that the target vehicle learns the disabled vehicle key in time. The cloud also sends a second disabled state code representing the disabled device identifier to the vehicle key, so that the vehicle key determines whether it has become a disabled vehicle key according to the second disabled state code.
