Abstract
Disclosed herein are system, method, and computer program product embodiments for identity obscuration of a station (STA) connected to a wireless network to prevent the tracking of the STA. Embodiments include a STA configured to establish a security association with an access point (AP) based on an original long term identity for the station and an identity of the AP. The STA can transmit a new long term identity for the STA to the AP based on the security association. The STA can then transmit a request frame to change the original short term identity assigned to the STA to the AP. The STA can receive a response frame from the AP. The response frame can include a new short term identity assigned to the station by the AP. The STA can then map its new long term identity to its new short term identity assigned by the AP.
