GPS spoofing is a problem that is receiving increasing scrutiny due to an increasing number of reported attacks. Plenty of results have been reported on detecting the presence of GPS spoofing attacks. However, very few results currently exist for the localization of spoofing attackers, which is crucial to counteract GPS attacks. In this paper we propose leveraging vehicle-to-vehicle communications to detect and localize spoofing attacks on vehicular navigation GPS. The key idea is to correlate Doppler shift measurements which are reported by most commercial GPS receivers. The approach does not need additional dedicated devices and is easily deployable on modern vehicles equipped with vehicle-to-vehicle communication devices. It is capable of localizing both stationary spoofers and mobile spoofers which could be mounted on a vehicle. Both numerical simulations and experimental tests are conducted to confirm the effectiveness of the proposed approach.
