Abstract
This application provides a security authentication method and apparatus applied to Wi-Fi. An access point AP negotiates, based on a password, a pairwise master key PMK with a first device based on a twin base password encrypted key exchange TBPEKE protocol, where the password is a shared key between the AP and the first device; and the AP performs a 4-way handshake with the first device based on the PMK. Therefore, in embodiments of this application, a PMK with a high entropy value can be generated by performing a TBPEKE procedure, so that the security authentication method provided in embodiments of this application can help resist an offline dictionary attack.
