  • 802.11 PHY HASHED SSID
    Publication number: 20130235859
    Abstract: An access point (AP) hashes its SSID/BSSID according to a hashing function H and transmits wirelessly the hashed SSID/BSSID within a physical layer frame/packet to a user station (STA). The hashed SSID/BSSID uniquely identifies the AP. In one embodiment, the hashed SSID/BSSID is transmitted within a SIGNAL field of a preamble with the frame/packet. Upon receipt, the user station recovers the hashed SSID/BSSID and compares it to an expected hashed SSID/BSSID (calculated using the same hashing function H and a desired SSID/BSSID). In response to the comparison, the user station performs one or more actions.
