Detecting and Preventing an Adversarial Network Entity from Tracking a Wireless Device's Location

摘要

Methods for detecting and preventing an adversarial network entity (e.g., fake base stations, etc.) from tracking a wireless device's location. A wireless device may be equipped with a random value (RAND) database or cache memory RAND values previously received by the wireless device. In response to receiving an authentication request message from a network component, performing AKA procedures and determining that the authentication failed, the wireless device may compare the RAND value included in the received authentication request message to RAND values stored in secure storage memory. The wireless device may generate an authentication response message that includes an error code that is different than standard error code used so that the target wireless device can't be differentiated from other wireless devices thereby preventing tracking in response to determining that the RAND value included in the received authentication request message is included in the RAND secure storage memory.
