Abstract: This application discloses an identity authentication method, a device, and a system. The method includes: obtaining a first master public key and a first private key from a key generation center; sending a ClientHello message; obtaining a second identity from a ServerKeyExchange message; generating a pre-shared key of a selected PSK mode by using the second identity, the first private key, and the first master public key; and completing identity authentication with a second device by using the pre-shared key. According to the method, device, and system provided in embodiments of this application, an identity can be transmitted by using information in the TLS protocol, without extending the TLS protocol. This can avoid a compatibility problem caused by TLS protocol extension.

Abstract: A temporary MAC address-based access method, apparatus, and system is provided. A method includes performing wireless communication access authentication on a base station for a non-base station device (STA) by sending, from the base station to the STA, a message indicating whether the base station supports the STA in using a temporary MAC address (TMA), receiving, at the base station, an authentication message in response to the message. The authentication message is sent by the STA to the base station by using the TMA in response to determining that the message indicates that the base station supports the STA in using the TMA. The method further includes parsing out the TMA by using the authentication message and sending an authentication response message to the STA according to the authentication message. The authentication response message indicates whether the base station allows the STA to use the TMA for communication.
