A beacon and Action frame are broadcasted. The SSID in the beacon is hidden (32-bytes with value 0). For [[#Scan]]/[[#ScanPrivate]] it doesn't matter if no beacon is available ([[#NetworkInfo]] is the same), as long as the Action frame is broadcasted. However, the Station will not send a probe-request during connection if no beacon is available (and therefore not attempt any communication with the AccessPoint).

During connection, the Station first sends a probe-request using the [[#NetworkInfo|generated]] SSID from the Action frame. If the probe-response contains the expected data for the [[#SecurityConfig]] type, the Station then proceeds to connect to the AccessPoint. The key for data-frames, if [[#SecurityConfig|enabled]], is derived from a buffer containing: {[[#SecurityParameter]]+0x0} followed by {[[#SecurityConfig]] data with the specified data-size}. The [[#ActionFrame]]/data-frame keys are derived with the same func, the only difference is the input passed to this func + the passed constant data. The key derived by ldn is used directly as the static CCMP key for all data-frames.
