Abstract: Embodiments of this application provide a Wi-Fi communication method and apparatus, and relate to the wireless communication field. A station may obtain detection information including a start time point at which an access point actually sends a beacon packet to the station for one time, obtain a low power consumption parameter based on the detection information and a first time interval, and receive the beacon packet from the access point based on the low power consumption parameter. The low power consumption parameter includes an actual wakeup periodicity of the station and an actual receive window length within which the station receives the beacon packet, or the low power consumption parameter includes an actual wakeup periodicity of the station, and the actual wakeup periodicity of the station is greater than a preconfigured wakeup periodicity of the station.

Abstract: This application discloses a Wi-Fi security authentication method and a communication apparatus. In the method, an access point AP receives a first access request from a supplicant, where the first access request carries a first parameter, and the first parameter is a parameter generated by the supplicant based on a generator of a set cyclic group and a first random number; generates a second random number, generates a second parameter based on the second random number and the generator of the set cyclic group, and sends the second parameter to the supplicant; generates a second pairwise master key based on the second random number, the first parameter, the second parameter, and a first target random key; and performs a four-way handshake authentication procedure with the supplicant based on the first pairwise master key and the second pairwise master key.

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.
