Abstract
A device authentication method and an apparatus are provided, to solve the problem of how to perform an authentication for the device in a UUDN. The method includes: obtaining, by a target access point (AP), a first timestamp sent by a local service center (LSC) device and a second timestamp sent by a terminal, where the second timestamp is sent by the LSC device to the terminal, and the first timestamp and the second timestamp are sent by the LSC device based on an AP switching event; when the first timestamp is consistent with the second timestamp, determining, by the target AP, that the terminal is an access terminal of the target AP.
