Abstract: In a method for conducting communications, a first terminal device in a vehicle-to-vehicle (V2V) network sends a first request message to a server of the V2V network to request the server to allocate an encryption key corresponding to a first service. The first request message includes an identifier of the first service and an identifier of the first terminal device. The first terminal device receives from the server a first response message that includes an encryption key corresponding to the first service. The first terminal device uses the encryption key to encrypt first information related to the first terminal device in the V2V network, and broadcasts a broadcast message that includes the encrypted first information to the V2V network.
