At present, with the development of the Internet of Vehicles technology, vehicles can be controlled by terminals in related technologies.
Before controlling the vehicle through the terminal, the terminal needs to obtain the digital key information of the vehicle to be controlled. The digital key information of the vehicle can be sent to the terminal only after network authentication of the vehicle. However, vehicles can send digital key information to terminals only when they are connected to the Internet in real time, thus leading to unsatisfactory user experience.
Therefore, the embodiment of the application provides an information reading method, apparatus, system and storage medium, which enables a terminal to control the vehicle through digital key information when the vehicle is not connected to the network, thereby improving the user experience.
In order to facilitate understanding of the embodiments of this application, firstly, the information reading system provided by the embodiments of this application is described in detail.
FIG. 1 is a schematic structural diagram of an information reading system provided by an embodiment of the present application.
Referring to FIG. 1, wherein the information reading system provided by the embodiment of this application may include a terminal 101, a server 102 and a vehicle 103.
Terminals may be mobile electronic devices, such as mobile phones, tablet computers, notebook computers, palm computers, wearable devices, and so on. The terminal is used for determining the information of the vehicle that is pre-controlled by the terminal and the time length of the terminal controlling the vehicle based on the request information sent by the terminal. The information of the vehicle that is pre-controlled by the terminal may be the vehicle identity. A server may determine the digital key information according to the information of the vehicle that is pre-controlled by the terminal and the required time length for the terminal to  control the vehicle and then send it to the terminal. When the terminal needs to use the digital key information to control the pre-controlled vehicle, the terminal needs to transmit the digital key information to the vehicle, so that the terminal can use the digital key information to control the vehicle.
The vehicle can obtain the digital key information from the terminal. For example, near field communication methods, such as Bluetooth communication, Near Field Communication (NFC) and Ultra Wide Band (UWB) , can be adopted.
Here, the vehicle may also be equipped with one of the following terminals such as a smart door lock and a home gateway.
Based on the information reading system provided by the above embodiments, the information reading method provided by the embodiments of this application will be described in detail with the information reading system as the main body of execution, with reference to the drawings and specific embodiments.
FIG. 2 is a flow diagram of an information reading method provided by an embodiment of the present application.
According to FIG. 2, the information reading method provided by the embodiment of this application may include the following steps.
At S201, the terminal sends request information to the server.
The request information refers to the request information of the terminal sent to the server to control the digital key information of the pre-controlled vehicle, herein the request information includes a first vehicle identity and a preset time length. The first vehicle identity refers to the identity of the vehicle that is pre-controlled by the terminal. The preset time length refers to the time length for the terminal to control the pre-controlled vehicle.
For example, if the user needs to control a vehicle B through a terminal A, the user needs to send the request information to the server through the terminal A, herein the request information includes the identity of the vehicle B and the time length that the terminal A can control the vehicle B.
At S202, the server determines digital key information according to the first vehicle identity and the preset time length.
After the server receiving the request information sent by the terminal, the server generates digital key information of the vehicle that is pre-controlled by the terminal according to the first vehicle identity and the preset time length in the request information. Here, the preset time length is the aging time of the digital key information.
For example, if the user needs to control the vehicle B through the terminal A for two hours, the digital key information may expire two hours after the terminal obtains the digital key  information, and the terminal A cannot control the vehicle B with the digital key information after two hours.
At S203, the server sends digital key information to the terminal.
At S204, the terminal stores the digital key information.
At S205, the vehicle reads the digital key information in the terminal through near field communication.
Near field communication may include Bluetooth communication, NFC and UWB. When the user obtains the digital key information of the pre-controlled vehicle through the terminal, the vehicle will be controlled through the terminal. At this time, the user can put the terminal close to a Secure Element (SE) provided on the vehicle, herein SE on the vehicle can read the digital key information from the terminal through near field communication, so the user can control the vehicle through the terminal.
Optionally, in one embodiment of this application, in order to improve the security of the digital key information during transmission and use, the server needs to encrypt the digital key information after the server determines the digital key information.
Specifically, the digital key information is encrypted with an information encryption key; signature information is generated according to the encrypted digital key information; signature information is sent to the terminal, and the terminal can transmit the signature information to the vehicle, and the vehicle verifies the digital key information that the vehicle reads from the terminal based on the signature information.
An information encryption key is a preset encryption key, herein the information encryption key is stored in the terminal and the vehicle. Here, the information encryption key stored in the server, the information encryption key stored in the terminal and the information encryption key stored in the vehicle are all the same.
The server uses the information encryption key to encrypt the digital key information, thereby generating a signature information of the digital key information. For example, the encrypted digital key information is hashed to obtain the signature information of the digital key information. The server sends the signature information corresponding to the digital key information to the terminal, so that the vehicle can read the digital key information and the signature information when reading information from the terminal. The vehicle verifies the digital key information based on the signature information to confirm whether the digital key information has been tampered with in the process of information transmission, thus ensuring the information transmission safety of the digital key information.
Optionally, in another embodiment of this application, the server further needs to generate target parameters according to a first vehicle identity for the terminal to authenticate  the vehicle before controlling the vehicle.
Specifically, target parameters corresponding to the first vehicle identity is generated; a fifth key and a sixth key are generated according to the target parameters, the preset first key and the preset second key; and a fifth key and a sixth key are sent to the terminal for the terminal to authenticate the vehicle.
The target parameters may be a dispersion factor randomly generated according to the first vehicle identity. For example, the server randomly generates a 16-byte dispersion factor based on the first vehicle identity. Here, the target parameters are in one-to-one correspondence with the first vehicle identity.
The first key and the second key are both preset. A fifth key is determined based on the target parameters and the first key, and a sixth key is determined based on the target parameters and the second key. And the fifth key and the sixth key are transmitted to the terminal and the terminal can authenticate the vehicle based on the fifth key and the sixth key.
Optionally, in one embodiment of this application, the vehicle can obtain the digital key information from the terminal through near field communication, so that the terminal can control the vehicle based on the digital key information.
In order to ensure the security of information, the vehicle and the terminal need a two-way authentication.
First of all, the process of vehicle authenticated by terminal is introduced in detail.
Specifically, a fifth key and a sixth key sent by a server are received, herein the fifth key is generated by the server according to the target parameters and the preset first key; and the sixth key is generated by the server according to the target parameters and the preset second key.
A third key and a fourth key sent by a vehicle are received;
The vehicle is authenticated according to the third key, the fourth key, the fifth key and the sixth key.
When the third key and the fifth key are consistent, and the fourth key and the sixth key are consistent, the vehicle authentication is passed, and the digital key information is transmitted to the vehicle.
The third key is generated by the vehicle based on the target parameters and the first key preset in the vehicle, and the fourth key is generated by the vehicle based on the target parameters and the second key preset in the vehicle.
Among them, the target parameters in the vehicle are read by the vehicle from the terminal. Before the vehicle reads the digital key information through near field communication, the vehicle will send a second vehicle identity to the terminal, i.e., the identity of the vehicle. After receiving the second vehicle identity, the terminal will verify whether the first vehicle  identity is consistent with the second vehicle identity. If the first vehicle identity is consistent with the second vehicle identity, it is proved that the vehicle is a pre-controlled vehicle by the terminal.
When the first vehicle identity is verified to be consistent with the second vehicle identity, the terminal sends the target parameters to the vehicle.
The terminal receives the fifth key and the sixth key sent by the server, and also needs to receive the third key and the fourth key sent by the vehicle.
When the third key and the fifth key are consistent, and the fourth key and the sixth key are consistent, the terminal can pass the authentication of the vehicle, and then the terminal can transmit the digital key information to the vehicle.
Secondly, the process of terminal authenticated by the vehicle is introduced in detail.
The vehicle reads the digital key information and the signature information of the digital key information from the terminal and verifies the digital key information based on the signature information.
Here, the digital key information may also be encrypted digital key information. Only after the signature information is verified, the digital key information can be decrypted.
For example, in order to ensure the integrity and security of information during transmission, after receiving the digital key information and the signature information, the vehicle needs to check whether the signature in the signature information is correct. If the signature is correct, the encrypted digital key information is decrypted by using the information decryption key pre-stored in the vehicle.
Optionally, in some embodiments of this application, the vehicle also needs to verify whether the information format of the digital key information is consistent with the information format specified in the vehicle, and whether the vehicle identity included in the digital key information is consistent with the vehicle identity of the vehicle. When the information format of the digital key information is consistent with the information format specified in the vehicle, and the vehicle identity included in the digital key information is the vehicle identity, the digital key information is stored, and then the terminal can use the digital key information to control the vehicle.
Optionally, in some embodiments of this application, after the vehicle stores the digital key information, the vehicle also generates a white list information. The white list information includes the terminal identity of the terminal controlling the vehicle and the time length of the terminal controlling the vehicle. When the time length of the terminal identity controlling the vehicle is longer than the preset time length, the digital key information of the terminal controlling the vehicle is invalid, and the terminal cannot use the digital key information to  control the vehicle.
According to the information reading method provided by the embodiment of the application, herein when the vehicle cannot be connected to the network, the request information is sent to the server through the terminal, herein the request information includes the vehicle information that the terminal needs to transmit digital key information and the preset time length for using the vehicle. The server can determine the digital key information according to the vehicle information and the preset time length. In this way, the terminal can obtain the digital key information from the server and the vehicle can read the digital key information in the terminal based on the near field communication. In this way, the server can push the digital key information to the vehicle without networking, so the user can control the vehicle through the terminal anytime and anywhere, thus improving the user's experience.
Based on the information reading method provided by the embodiment of the application, herein an information reading apparatus based on the terminal side is provided. The information reading apparatus will be described in detail below.
