In order to ensure that the vehicle control commands are not tampered, the mobile terminal encrypts the vehicle control commands by using a third random number R3 and sends the vehicle control commands to the vehicle-mounted terminal by using an encrypted vehicle control ciphertext M.
Since the R3 is encrypted to R33 by the vehicle-mounted terminal, the mobile terminal performs inverse operation on the encrypted random number R33 by using the session key SK, and decrypts the encrypted random number to obtain the third random number R3.
