Example 1
As shown in fig. 1, the vehicle-mounted control terminal of the present embodiment includes a first chip 100, a second chip 200, a control background 400, and an electronic control unit controller 300.
The first chip 100 and the second chip 200 represent a plurality of chips with different functions existing in a vehicle-mounted control terminal, for example, an MCU (Microcontroller Unit, micro control unit) or an SOC (system on chip) chip, etc., and these chips are often plural in one vehicle-mounted control terminal.
The electronic control unit controller 300, that is, an ECU (Elecmal Control Unit, electronic control unit) controller is an electronic control unit of an automobile, and the control background 400 is, for example, a TSP (Telematics Service Provider, content service providing) background or the like. The control background 400 is connected to the first chip 100 for internal communication, the first chip 100 is connected to the second chip 200 for transmitting a control command from the control background 400, and the second chip 200 is connected to the electronic control unit controller 300 for transmitting the control command to the electronic control unit controller 300 for realizing the control operation of the control command on the vehicle.

The inter-core communication key is a key used for encryption and decryption when encryption communication is carried out between the first chip and the second chip, and the encryption and decryption algorithm can be a symmetric encryption algorithm such as AES or DES.
The above-mentioned first encryption module and second encryption module can be HSM or TEE this kind of chip that is used for encrypting and decrypting specially, and because of the characteristic of this kind of chip, after the key burns into the chip from the time of leaving the factory, just become unreadable usable data, it is difficult for the hacker to crack to strengthen the security of key itself.
The first chip is also used for establishing secure communication with the control background, and when the first chip acquires a control command from the control background, the first encryption module encrypts the control command through the inter-core communication key and sends the encrypted control command to the second chip.
Specifically, a first key is also stored in a first encryption module of the first chip, and the first chip sends a connection request to the control background;

Example 2
As shown in fig. 2, the present embodiment provides an inter-core secure communication method, which is applied to the vehicle-mounted control terminal in embodiment 1, and includes:
and step S100, the first chip establishes secure communication with the control background through the first encryption module so as to acquire a control command from the control background.
As shown in fig. 1, the first chip also communicates with the control background, so that, for the first chip, in addition to the secure communication with the second chip, secure communication with the control background is also required, so that data from the controlled state is also secure in the transmission link.
Specifically, the first chip is described as an example in which the SOC chip and the control background are TSP background.
The SOC chip establishes TLS communication with the TSP background through its own communication function, and during the handshake process, because the SOC chip is internally provided with a first encryption module, for example, a TEE module, the SOC chip may use a first key preset in the TEE to sign communication data for handshake verification with the TSP background, where the first key may be a key of various encryption algorithms such as an RSA key, and the specific encryption algorithm is not further limited in this embodiment.
The interaction flow of the first chip and the control background for establishing the secure communication is shown in fig. 3.
After the first chip and the control background make a call in the hello stage, the first chip sends a connection request to the control background and receives a reply message from the control background, then the first chip acquires a server side certificate of the control background, the server side certificate comprises a public key and a signature, the first chip signs the server side certificate through a first secret key of the first chip, and sends signed data and the public key of the first chip to the control background to complete handshake communication of the first chip and the control background and establish the secure communication. Thus, the data interaction between the control background and the first chip can be processed through the first key, and the safe communication between the first chip and the control background is realized.
Step S200, after the first chip receives the control command, encrypting the control command through the inter-core communication key, and then sending the encrypted control command to the second chip;
the control background sends control commands to the first chip, the first chip needs to send the control commands to the second chip, and the second chip sends the control commands to the controller of the electronic control unit, however, directly sending the control commands in the clear text can cause the commands to be unsafe in the communication process and easy to steal and tamper, so encryption is needed, and in this embodiment, the encryption and communication operation of the control commands are realized by storing the same inter-core communication keys in the first chip and the second chip.
Specifically, as shown in fig. 4, when a control command enters the first chip, the control command is encrypted by the first encryption module, wherein the control command is encrypted by using the inter-core communication key, and the encrypted control command is sent to the second chip.
As can be seen from the above step S100, the control command is generally sent from the control background, so that the control command sent at this time is also generally encrypted, so that the first encryption module needs to decrypt the control command sent by the line into plaintext by using the first key, and then encrypt the control command by using the inter-core communication key to obtain a new ciphertext, so that the second chip can perform the decryption operation.
And step S300, when the second chip receives the data from the first chip, determining whether the data is an encrypted control command, and if so, decrypting the encrypted control command to obtain the control command in the plaintext.
When the second chip receives the data from the first chip, the second chip firstly judges whether the control command is an encrypted control command, if so, the control command is transmitted to the second encryption module for processing, and the second encryption module is internally provided with an inter-core communication key, so that the control command can be decrypted according to the inter-core communication key to obtain the plaintext of the control command.
In addition, secure communication is also required between the second chip and the controller of the electronic control unit, that is, the second chip encrypts the decrypted control command again and then sends the encrypted control command to the electronic control unit.
The second chip encrypts the control command through the second key to obtain a board-end encrypted communication message, and sends the board-end encrypted communication (SECOC) message to the electronic control unit controller.
Specifically, the control command is encrypted through the second key to obtain an encrypted command, slicing is performed according to the encrypted command to generate authentication information, then a freshness value is obtained, and the freshness value, the authentication information and the encrypted command are packaged to obtain the board-end encrypted communication message.
Wherein freshness value is used to convey real-time nature of the information, may be generated by both modes of time stamp check and frame counter check. May be considered as a time-dependent data to indicate whether the data transferred is real-time data.
In summary, the inter-core secure communication method provided by the application can be applied to the vehicle-mounted control terminal, and aiming at the interaction among a plurality of chips in the vehicle-mounted control terminal and a plurality of chips which can be encountered, by arranging the encryption module in the chip and writing different keys into different communication paths, each communication session is ensured to be protected through encryption operation, meanwhile, the keys are not stored in a clear text, so that the key is harder for a hacker to crack, and a fake command is harder to generate to enter the device, thereby improving the security of the intelligent automobile.
The application also provides an intelligent automobile, which is provided with the vehicle-mounted control terminal, and the vehicle-mounted control terminal executes the inter-core safety communication method.
