The implementation details of the technical solutions of the embodiments of the present application are described in detail below:
fig. 1 is a schematic diagram of an application scenario according to an embodiment of the present application, where, as shown in fig. 1, the application scenario includes a vehicle-mounted intelligent terminal and an external device communicatively connected to the vehicle-mounted intelligent terminal through a network, where the network may be a wide area network or a local area network, or a combination of the two.
The external device may be a server or a user terminal (e.g., a cell phone, a computer, a tablet computer, etc.), etc. The external device can interact data with the in-vehicle local area network through the network. The in-vehicle local area network comprises a vehicle-mounted intelligent terminal and a controller. The controller is used for storing and processing data, and the vehicle-mounted intelligent terminal is used for carrying out data interaction with external equipment and the controller.
When external equipment and an in-car local area network perform data interaction, the external equipment sends a data interaction verification request to the in-car local area network, the in-car intelligent terminal responds to the data interaction verification request, generates a second safety key based on the key seed, verifies the reliability of the external equipment by using the second safety key and the first safety key, and opens data access authority to the external equipment when the external equipment is verified to be reliable, at the moment, the external equipment can send a session request to the in-car intelligent terminal, and when the in-car intelligent terminal receives the session request sent by the external equipment, the session request is forwarded to the controller so that the controller verifies user information in the session request, and if the controller verifies that the user information in the session request is reliable, a verification passing result is fed back to the in-car intelligent terminal. And if the vehicle-mounted intelligent terminal receives the verification passing result fed back by the controller, a data transmission channel between the vehicle-mounted intelligent terminal and the controller is established, wherein the data transmission channel is used for carrying out data interaction on a user account corresponding to the user information through the vehicle-mounted intelligent terminal and the controller. Therefore, when the external equipment is verified to be reliable and the user account of the external equipment is reliable, the external equipment and the controller can perform data interaction, and the reliability and the safety of the external equipment when the external equipment and the controller interact are improved.
Fig. 2 is a flowchart of a method for data interaction of an in-vehicle local area network according to an embodiment of the present application, which may be performed by an in-vehicle intelligent terminal in the in-vehicle local area network as shown in fig. 1 with processing capability. Referring to fig. 2, the method at least includes steps S110 to S140, and is described in detail as follows:
step S110: and receiving a data interaction verification request sent by the external equipment, wherein the data interaction verification request carries a key seed and a first security key obtained by the external equipment based on the key seed.
The external device may specifically be a background server, or may be a user terminal, such as a mobile phone, a computer, or other terminal devices, where the external device may be a device that needs to access data of a controller in a vehicle, or may be a device that needs to synchronize data with the controller of the vehicle, and may be set according to actual requirements.
It should be appreciated that the interactive proof request sent by the external device is for establishing contact with the vehicle for subsequent data interaction.
The key seed carried in the data interaction request refers to an initial key for starting a key updating process or a key generating process. When the external device obtains the first security key based on the key seed, a key generation algorithm, such as an RSA algorithm or a DSE algorithm, may be specifically adopted.
Step S120: and responding to the data interaction verification request, generating a second security key based on the key seed, and verifying the reliability of the external device by using the second security key and the first security key.
It should be appreciated that when the vehicle-mounted intelligent terminal generates the second secure key based on the key seed, the same key generation algorithm is used as when the external device generates the first secure key based on the key seed, and the key generation algorithm may be stored in advance by the external device and the vehicle-mounted intelligent terminal respectively (for example, may be stored in advance when the external device and the vehicle-mounted intelligent terminal are confirmed to be trusted devices), and when the first secure key is the same as the second secure key, the external device may be confirmed to be trusted.
Step S130: and if the external equipment is verified to be reliable, opening the data access authority to the external equipment, and forwarding the session request to the controller when receiving the session request so as to enable the controller to verify the user information in the session request.
When the vehicle-mounted intelligent terminal opens the data access right to the external equipment, the vehicle-mounted intelligent terminal and the external equipment can perform data interaction. If the external device needs to further perform data interaction with the controller in the vehicle, the reliability of the user performing the access operation in the external device needs to be further verified. Specifically, when the vehicle-mounted intelligent terminal opens the data access right to the external device, the external device can send a session request through the vehicle-mounted intelligent terminal so as to request data interaction with the controller through the vehicle-mounted intelligent terminal. The user information carried in the session request may specifically include identification information (such as a user ID) of the user and a user password.
Forwarding the session request to the controller when receiving the session request, so that the controller verifies the user information in the session request, including:
when receiving a session request, transmitting a user ID in the session request to a controller so that the controller inquires whether a user ID is included in a stored user list; and if ID confirmation feedback information fed back by the controller when the user list comprises the user ID is received, sending a user password corresponding to the user ID to the controller so that the controller verifies the user password based on the password corresponding to the user ID in the user list.
It should be understood that when there is a preset ID corresponding to the user ID in the user list, and the password corresponding to the preset ID is consistent with the user password corresponding to the user ID, the verification is passed. Otherwise, the verification fails, namely if the preset ID corresponding to the user ID does not exist, or when the preset ID corresponding to the user ID exists but the password corresponding to the preset ID is inconsistent with the user password corresponding to the user ID, the verification fails.
Step S140: if a verification passing result fed back by the controller is received, a data transmission channel between the vehicle-mounted intelligent terminal and the controller is established, wherein the data transmission channel is used for carrying out data interaction between a user account corresponding to the user information and the controller through the vehicle-mounted intelligent terminal.
In one embodiment of the application, after the data transmission channel between the vehicle-mounted intelligent terminal and the controller is established, the user account corresponding to the user information can perform data interaction between the vehicle-mounted intelligent terminal and the controller by using a preset transmission protocol based on the data transmission channel.
The data transmission protocol may be an FTP protocol, where the FTP protocol is a common protocol in network transmission protocols, and basically has good application support on the above mentioned operating system, and has high compatibility. As long as the controller end can be used as a server end of the FTP, other nodes (such as a vehicle-mounted intelligent terminal in the application) can be used as clients of the FTP, and data interaction is carried out with the controller.
By using the standard FTP protocol, is integrated into the controller. Based on the FTP protocol, the innovative extensions support custom commands. And the high-rate characteristic of the Ethernet is combined, so that the transmission capacity is greatly improved, and the problem of the transmission rate is solved. Meanwhile, the external equipment can access the controller through the FTP protocol by the vehicle-mounted intelligent terminal, so that the functions of remote configuration, remote data acquisition and the like are realized, and the remote service function is enriched.
It should be appreciated that, in order to make the data access more reliable, it should be appreciated that the controller may also store account access rights corresponding to different preset IDs, so that the FTP protocol characteristic is utilized to increase the rights of the user account, and one account is given one right, for example, the data that can be accessed is classified according to security, so that the user data in the controller can be effectively protected.
By adopting the data interaction method of the in-vehicle local area network, the reliability of the external equipment is required to be verified a priori before data interaction is carried out, the vehicle-mounted intelligent terminal opens the data access authority to the external equipment after verifying the reliability of the external equipment, and when receiving a session request sent by the external equipment, the controller is used for verifying the reliability of a user corresponding to the session request, and a data interaction channel between the controller and the vehicle-mounted intelligent terminal is established when the verification passes, so that the external equipment can carry out data interaction through the vehicle-mounted intelligent terminal and the controller, and the reliability and the safety of the data interaction are ensured.
It should be understood that after the data transmission channel between the vehicle-mounted intelligent terminal and the controller is established, the external device may access the data stored in the controller through the data transmission channel between the vehicle-mounted intelligent terminal and the controller, and the external device may synchronize the data into the controller through the data transmission channel between the vehicle-mounted intelligent terminal and the controller.
In one implementation manner, if the vehicle-mounted intelligent terminal receives a data acquisition request corresponding to a user account sent by an external device, the vehicle-mounted intelligent terminal sends the data acquisition request to a controller through the data transmission channel; and receiving target data fed back by the controller in response to the data acquisition request through the data transmission channel, and sending the target data to the external equipment.
If a data acquisition request corresponding to a user account sent by an external device is received, the data acquisition request is sent to a controller through the data transmission channel, including:
if a data acquisition request corresponding to a user account and sent by an external device is received, a file path parameter corresponding to the data acquisition request is obtained in response to the data acquisition request, and the data acquisition request and the file path parameter are sent to the controller through the data transmission channel, so that the controller can search target data according to the file path parameter in response to the data acquisition request.
In this way, the FTP protocol may be used for data interaction in the data interaction process. The target data may be a battery level of the vehicle, traveling routine information, a fault condition of each node, and the like. When a vehicle breaks down, the data information can be used for rapidly identifying the cause of the fault, and the analysis and the solution of the problem are facilitated.
In another implementation manner, if the vehicle-mounted intelligent terminal receives a data input request corresponding to a user account sent by an external device, the data input request is sent to a controller through the data transmission channel, so that the controller responds to the data input request to input a file to be input carried in the data input request into a corresponding file system; and receiving an input result fed back by the controller in response to the data input request through the data transmission channel, and sending the input result to the external equipment.
Referring to fig. 3, an embodiment of the present application further provides a data interaction method of an in-vehicle local area network, which is applied to a controller in the in-vehicle local area network, where the in-vehicle local area network further includes an in-vehicle intelligent terminal, and vehicle operation data is stored in the controller, and the method includes:
step S210: and receiving a session request forwarded after the vehicle-mounted intelligent terminal opens the data access right to the external equipment, wherein the data access right is opened when the reliability verification of the external equipment is passed.
For a specific process of performing the reliability verification on the external device, reference may be made to the foregoing specific descriptions of steps S110 to S120, which are not described herein in detail.
Step S220: and if the user information in the session request is successfully verified, sending a verification passing result to the vehicle-mounted intelligent terminal so that the vehicle-mounted intelligent terminal establishes a data transmission channel between the vehicle-mounted intelligent terminal and the controller, wherein the data transmission channel is used for carrying out data interaction between a user account corresponding to the user information and the controller through the vehicle-mounted intelligent terminal.
For the specific description of step S220, reference may be made to the foregoing specific descriptions of steps S130 to S140, which are not repeated here.
The controller can also store access rights corresponding to different user information, for example, a general user only concerns configuration information of a vehicle or background log information of the vehicle, and only needs to open user-level rights; and the system user considers the system running state information, the security information or the encryption information and the like, and needs to allocate system level authority, so that the system authority can access the system information and the user level data, and the security of the data access can be further ensured.
It should be understood that after the establishment of the data transmission channel is completed later, if a data acquisition request sent by the vehicle-mounted intelligent terminal is received, a file path parameter corresponding to the data acquisition request can be obtained, and target data is searched according to the file path parameter in response to the data acquisition request and fed back to the vehicle-mounted intelligent terminal.
If the user information corresponds to the access right, when a data acquisition request sent by the vehicle-mounted intelligent terminal is received, a file path parameter corresponding to the data acquisition request can be obtained, whether a storage position corresponding to the file path parameter belongs to a storage space to which the access right corresponding to the user information belongs or not is determined, if yes, target data are searched according to the file path parameter, and the target data are fed back to the vehicle-mounted intelligent terminal.
Similarly, if the data input request sent by the vehicle-mounted intelligent terminal is received after the establishment of the data transmission channel is completed later, the file to be input carried in the data input request is input into the corresponding file system in response to the data input request.
