“With millions of GPS-based navigation devices on the road today, it is time someone considered the question: What if there’s an attack on the GPS network itself?” Continue reading the WIRED Gadget Lab article.

“Computers have been hacked for decades. But now, scientists at Cornell University and Virginia Tech are now warning about the dangers of “spoofing,” or hacking into the Global Positioning System (GPS) that controls everything from car navigation to national power grids.” Continue reading the Discovery News article.

“The Global Positioning System (GPS) lies at the heart of an increasing number of technologies, from vehicle navigation systems to the power grid. And yet, although the military version of GPS includes security features such as encryption, civilian signals are transmitted in the clear. Now, researchers at Cornell University and Virginia Tech have demonstrated a

“Just like flat-screen televisions, cell phones and computers, global positioning system (GPS) technology is becoming something people can’t imagine living without. So if such a ubiquitous system were to come under attack, would we be ready?” Continue reading the Cornell Chronicle article.

Washington, D.C. — Dr. Humphreys briefed the National Space-Based Positioning, Navigation, and Timing (PNT) Executive Committee (EXCOM) Advisory Board on civil GPS spoofing. His presentation, “Spoofing the Timing Signal: What Else is Vulnerable? Understanding Potential Impacts to Infrastructure,” highlighted the Radionavigation Lab’s radionavigation security research including the RNL civil GPS spoofer (video) and a proposal for GNSS message authentication.

Background: The Global Positioning System has been a marvelous success over the past three decades. One consequence of this success is a deepening dependence of the civil infrastructure on GPS—especially for timing synchronization. As civil dependence on GPS grows, the potential for financial gain or high-profile mischief combine to make denial or manipulation of GPS

Dr. Humphreys talked with the BBC radio show, “The Naked Scientists,” about potential GNSS vulnerabilities. Helen: So this sounds to me a little bit like when we had computers and we didn’t yet know anything about computer viruses. Almost that there’s a potential for someone to come along and mess around with the GPS and
