Transmission method of authentication information and terminal

Abstract

Disclosed are a transmission method for authentication information, and a terminal. The method comprises: after a first terminal adopting a direct communication manner for sending authentication information with the assistance of a cellular network receives a first direct communication message, determining, by the first terminal, a communication manner adopted by a second terminal for sending the first direct communication message; and if the second terminal adopts a direct communication manner for sending authentication information carried thereby, carrying, by the first terminal, the authentication information in a second direct communication message sent to the second terminal. At the edge of a cellular network, by means of the technical solution provided in the embodiments of the present application, after determining that a direct communication message sent by a terminal adopting a direct communication manner for sending authentication information carried thereby is received, a terminal adopting a direct communication manner for sending authentication information with the assistance of the cellular network will carry the authentication information in the direct communication message sent thereby, so that the terminal adopting the direct communication manner for sending authentication information carried thereby can verify the validity of the direct communication message sent by the terminal adopting the direct communication manner for sending authentication information with the assistance of a cellular network according to the authentication information, thereby avoiding the road safety hidden danger.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method for transmitting authentication information and a terminal. Background technique [0002] The Internet of Vehicles technology refers to the direct communication between vehicles and vehicles, vehicles and infrastructure with the help of Dedicated Short Range Communications (DSRC) technology, real-time perception of the surrounding conditions of vehicles and timely warning of road safety. According to the transmission method of authentication information, the direct communication methods between vehicles and vehicles, and between vehicles and infrastructure can be divided into two categories: direct communication with authentication information carried by itself, and direct communication with cellular assistance in sending authentication information. [0003] In the direct communication mode of self-carrying authentication information (self-carrying...
