Step 101, AP determines the multiple encryption algorithms type that wireless service is supported.
Wherein, for multiple STA that WLAN comprises, each STA can support identical encryption algorithm type, also can support different encryption algorithm type.Therefore, wireless service needs the encryption algorithm type supporting that each STA is corresponding respectively, and often kind of encryption algorithm type corresponds to a kind of STA type.
In the embodiment of the present invention, the encryption algorithm type of wireless service support specifically includes but not limited to: TKIP type, AES-CCMP-SHA 1 type, AES-CCMP-SHA 256 type.Suppose that WLAN comprises 3 STA (STA1, STA2 and STA3), the encryption algorithm type that STA1 supports is TKIP type, and namely the STA type of STA1 is support the STA of TKIP type; The encryption algorithm type that STA2 supports is AES-CCMP-SHA 1 type, and namely the STA type of STA2 is support the STA of AES-CCMP-SHA 1 type; The encryption algorithm type that STA3 supports is AES-CCMP-SHA 256 type, and namely the STA type of STA3 is support the STA of ES-CCMP-SHA 256 type.
