Communication verification method and system, mobile terminal and vehicle terminal

The embodiment of the invention discloses a communication verification method and system, a mobile terminal and a vehicle-mounted terminal, and the method comprises the steps: initiating identity verification to the vehicle-mounted terminal through pre-stored first encryption information, wherein the first encryption information is obtained by encrypting a vehicle machine identity digital certificate through a first private key; initiating first key verification to the vehicle terminal in response to approval of the identity verification; in response to the fact that the first key verificationis passed, enabling the vehicle terminal to enter a safety mode; and receiving second key verification initiated by the vehicle terminal according to the network condition of the vehicle terminal, and determining a verification result. According to the embodiment of the invention, the security of the vehicle terminal is improved through identity verification and two times of key verification, andinterception and tamperin
