Location spoofing attack and its countermeasures in database-driven cognitive radio networks

The recent FCC ruling has enforced database-driven cognitive radio networks (CRNs), which include white space networks in TV bands (TV band CRNs) and newly proposed small cell networks in 3.5 GHz (3.5 GHz CRNs). In database-driven CRNs, a secondary user (SU) queries the database for available spectrum at its location. However, this creates a critical vulnerability to GPS spoofing attacks. Under this attack, an adversary compromises SUs' GPS localization system, which results in SUs querying the database with false locations and obtaining incorrect spectrum information. In this paper, we examine the impact of GPS spoofing attacks in database-driven CRNs and propose corresponding spoofing attack detection and countermeasure solutions. To the best of our knowledge, this is the first paper to study the impact and countermeasures of GPS spoofing attacks in database-driven CRNs.
