Step 210, the in-vehicle authentication unit sends a user authentication response to the authentication platform, and the response value is carried;
step 211, the authentication platform performs a third verification by comparing whether the response value is the same as the expected response value;
If the response value is the same as the expected response value, the user authentication is successful, and if the response value is not the same as the expected response value, the user authentication is failed;
step 212, the certification platform sends a certification response to the in-vehicle certification unit, which carries the result of the third verification.
