Abstract: A service discovery method and a service discovery apparatus enable a NAN device that does not support a multi-hop service discovery not to respond to a relayed multi-hop service discovery message on the premise that the relayed service discovery message is correctly received by a NAN device that supports the multi-hop service discovery. The method includes: receiving, by a second NAN device, a first service discovery message that is sent by a first NAN device and that is used for a service discovery; and generating, by the second NAN device based on the first service discovery message, a second service discovery message used for the service discovery, and sending the second service discovery message, where the second NAN device serves as a service relay device that relays the service discovery initiated by the first NAN device.

Abstract: The present invention provides a security authentication method, a configuration method, and a related device. A first terminal receives a public key for signature of a configuration device sent by the configuration device. The first terminal receives second signature information and second type information. The first terminal determines, according to at least the second type information and the second signature information, that the first terminal is to generate key information. In this way, the first terminal establishes a security connection between the first terminal and the second terminal. This effectively prevents a terminal from tampering with its role, and therefore effectively prevents a terminal from establishing a connection to an attacker terminal with a changed role, thereby further preventing the attacker terminal from obtaining information of the terminal, to effectively ensure security of the terminal.
