Abstract:
1. A method for establishing a data transmission channel, the method comprising: receiving a first authentication request message sent by a first terminal, wherein the first authentication request message comprises a terminal identifier of the first terminal and routing information of a second terminal; determining that the terminal identifier of the first terminal matches pre-stored authentication information of the first terminal; obtaining stored authentication information of the second terminal according to the routing information of the second terminal; sending, according to the routing information of the second terminal, a second authentication request message that carries the authentication information of the second terminal to the second terminal; receiving an authentication success response message from the second terminal that confirms that the authentication information of the second terminal in the second authentication request message matches a terminal identifier of the second terminal, wherein the authentication information of the second terminal and the terminal identifier of the second terminal meet a preset mapping relationship; and after receiving the authentication success response message, establishing a data transmission channel between the first terminal and the second terminal; wherein the first authentication request message further comprises a first authentication code generated by the first terminal at random and wherein, before the sending the second authentication request message to the second terminal, the method further comprises:
