Abstract:
Presented herein are techniques for GPS attack prevention in association with wireless communication devices. In at least one embodiment, a method may include receiving, at a mobile device from a first access point (AP), first location information and one or more of a first token or first neighbor information relating to neighboring APs. The mobile device may receive from a second AP, second location information and one or more of a second token or second neighbor information relating to neighboring APs. The first token may be compared to the second token to determine whether the first and second tokens are consistent, and/or the first neighbor information may be compared to the second neighbor information to determine whether the first and second neighbor information are consistent. It may be determined whether the first location information provided by the first AP and the second location information provided by the second AP are valid based on the comparison(s).
