Abstract

This application provides example authentication methods and apparatuses. One example authentication method is used for a terminal device. The method includes receiving, by the first service unit, a first request from a second device, wherein the first request is used to request a first seed. The first service unit sends the first request to the first authentication unit. The first authentication unit sends a first response to the first service unit, wherein the first response comprises the first seed. The first service unit sends the first response to the second device. The first service unit receives a second seed from the second device. The first service unit sends the second seed to the first authentication unit. The first authentication unit determines a third seed based on a first key and the second seed, wherein the first key is determined based on the first seed.
