Scientists Develop GPS-Spoofing Countermeasures

Cornell University researchers have demonstrated countermeasures designed to protect GPS-based devices from spoofing that could give hackers control of the systems. In a display that the US Department of Homeland Security sponsored, the scientists showed how GPS spoofing would work on a mini-helicopter and how they could prevent it. In a spoofing attack, which the researchers say is a growing threat, false GPS signals are transmitted to a device. The target receives them as authentic, enabling the hackers to gain control of the device. The scientists showed how they could detect and then counteract the spoofing.  They plan to patent their approach. (PhysOrg)(Cornell University)
