Dr. Todd Humphreys recently co-authored an article on GPS spoofing defenses with Dr. Mark Psiaki. This article is the cover story of the August 2016 issue of IEEE Spectrum magazine.
“Cellphone towers, stock exchanges, and the power grid all rely at least partly on GPS for precise timing. A well-coordinated spoof could interrupt communications, confuse automated financial traders, and inflict crippling power outages. In a worst-case scenario, a spoofer’s operator could overtake airplanes or ships to induce a crash, facilitate a heist, or even kidnap a VIP.”
“There are three main ways to protect against GPS spoofing: cryptography, signal-distortion detection, and direction-of-arrival sensing. No single method can stop every spoof, but Psiaki’s team has found that combining strategies can provide a reasonably secure countermeasure that could be commercially deployed.”
