Default Keys

Important The Native 802.11 Wireless LAN interface is deprecated in Windows 10 and later. Please use the WLAN Device Driver Interface (WDI) instead. For more information about WDI, see WLAN Universal Windows driver model.

The 802.11 station uses default keys for cipher operations on received multicast or broadcast packets. The station also uses default keys for cipher operations on sent or received unicast packets whenever a key mapping does not exist between the receiver's media access control (MAC) address and the transmitter's MAC address.

The 802.11 station must support a default key table that stores a minimum of four keys. If the miniport driver supports the Extensible Station (ExtSTA) mode, the 802.11 station can support a default key table size of four or greater.

The miniport driver, when operating in ExtSTA mode, reports the size of the 802.11 station's default key table when OID_DOT11_EXTSTA_CAPABILITY is queried.

For more information about the usage of default keys, refer to Clause 11.2.2.3 of the IEEE 802.11-2012 standard.
