Abstract: Provided are a method and device for acquiring a message certificate in a vehicle networking system. The method comprises: receiving, by a Background Control Center (BCC), a privilege certificate request instruction sent by an On-Board Unit (OBU); generating and sending, by the BCC, a write control instruction to the OBU, receiving, by the BCC, an application grant request instruction sent by the OBU, the application grant request instruction being used for applying for use of a privilege certificate already written in the OBU to the BCC; and determining, by the BCC, the valid time for the OBU to use a designated privilege certificate, generating an application control instruction according to the determined valid time, and sending the generated application control instruction to the OBU, the application control instruction being used for indicating that the OBU uses the designated privilege certificate within the valid time.

Abstract: Disclosed are a method and device for acquiring a message certificate in a vehicle networking system, so that the requirement that a message certificate required by a vehicle needing high passing priority is issued to the vehicle in an emergency is solved. The method comprises: receiving, by a BCC, an application license application instruction sent by an OBU, the application license application instruction being used for applying for use of a privilege certificate already written in the OBU to the BCC; and determining, by the BCC, the valid time for the OBU to use a designated privilege certificate, generating an application control instruction according to the determined valid time, and sending the generated application control instruction to the OBU, the application control instruction being used for indicating that the OBU uses the designated privilege certificate within the valid time, so that the OBU can use the privilege certificate designated by the BCC within the valid time determined by the BCC so as to enable the OBU to have the passing priority within the valid time determined by the BCC.
