Abstract
An identity authentication method is described. The method includes, when receiving a group joining request that is sent by a first terminal and that is used for joining a trusted group, generating, by a server, a first certificate for the first terminal based on a first version number, and sending them to the first terminal. The method further includes, when determining that a second terminal is removed from the trusted group, updating the first version number to a second version number; and separately generating, by the server based on the second version number, a corresponding second certificate for a terminal not removed from the trusted group; and separately sending the corresponding second certificate and the second version number to the terminal not removed from the trusted group. In this way, during authentication, a terminal may compare a version number of the other party to perform identity authentication, thereby improving authentication efficiency.
