[0047] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application. Figure 1 , a step flow chart of a vehicle machine encryption method provided by the embodiment of the present application is shown, and the method can include:

[0048] Step 101, in response to the start of the vehicle machine, detecting the vehicle identification code VIN code of the vehicle machine.

[0049] In the embodiment of the present application, in order to realize vehicle machine encryption and improve the flexibility of vehicle machine encryption to meet the safety requirements of the vehicle machine, the vehicle machine is not enabled for encryption on the vehicle machine production line, the production line efficiency is improved, and the vehicle machine is enabled for encryption by using the product serial number SN code of the vehicle machine after leaving the vehicle machine production line. When the vehicle machine is installed to the vehicle on the vehicle production line, the vehicle identification code VIN code of each vehicle machine is used as a seed to generate a secret key, and the password of the vehicle machine when leaving the factory is automatically invalidated. The password is used as the final password to realize vehicle machine encryption.

[0050] It should be noted that, in the embodiment, in response to the start of the vehicle machine, the vehicle identification code VIN code of the vehicle machine is detected to determine whether the vehicle machine is on the vehicle production line, so as to determine whether to use the SN code or the VIN code to encrypt the vehicle machine. The vehicle identification code VIN code is generated when the vehicle machine is installed to the vehicle on the vehicle production line, and is used to identify that the vehicle machine reaches the vehicle production line, so that the vehicle machine can be encrypted when the vehicle identification code of the vehicle machine is detected.

[0051] Step 102, in the case that the vehicle identification code VIN code is detected on the vehicle production line, deleting the product serial number SN code of the vehicle machine, and generating a secret key corresponding to the vehicle identification code VIN code according to the vehicle identification code VIN code and a preset password algorithm to encrypt the vehicle machine.

[0052] In the embodiment, in the case that the vehicle identification code VIN code is detected on the vehicle production line, it indicates that the vehicle reaches the vehicle production line, and the vehicle machine is installed to the vehicle. Therefore, the product serial number SN code of the current vehicle machine is deleted, the vehicle identification code VIN code is used as a seed, the secret key corresponding to the vehicle identification code VIN code is generated according to the vehicle identification code VIN code and a preset password algorithm, and the vehicle machine is encrypted.

[0053] It should be noted that the preset password algorithm in the embodiment is used for encrypting / decrypting the vehicle identification code VIN code, thereby realizing the encryption tamper-proof function of the car machine. The preset password algorithm in the embodiment can be any encryption algorithm capable of generating a secret key corresponding to the vehicle identification code VIN code, which is not limited here.

[0054] Specifically, the car machine generates a product serial number SN code in the car machine production line, and encrypts the car machine by using the secret key corresponding to the SN code according to the SN code in the last process of the car machine production line, so as to ensure the security of the car machine before it is installed in a vehicle. In the case that the vehicle identification code VIN code is detected in the vehicle production line, the product serial number SN code of the car machine is cleared, and the car machine is encrypted by using the secret key corresponding to the vehicle identification code VIN code according to the vehicle identification code VIN code and the preset password algorithm.

[0055] The embodiment of the application responds to the start of the car machine to detect the vehicle identification code VIN code of the car machine. The vehicle identification code VIN code is generated when the car machine is installed in a vehicle in the vehicle production line. In the case that the vehicle identification code VIN code is detected in the vehicle production line, the product serial number SN code of the car machine is deleted, and the car machine is encrypted by using the secret key corresponding to the vehicle identification code VIN code according to the vehicle identification code VIN code and the preset password algorithm. That is, the car machine is not encrypted in the car machine production line, the production line efficiency is improved, the encryption is automatically enabled when the car machine leaves the production line, the secret key generated by using the VIN code is used when the car machine is installed in a vehicle, the SN code password of the car machine when it leaves the factory is automatically invalidated, the secret key generated by using the VIN code is used as the final password, the car machine encryption is realized, the flexibility of the car machine encryption is improved, and the safety requirement of the car machine is met.
