ECE Professor Paul Kinter explains: "The first two authors of this article are recent Ph.D. graduates of Cornell's GPS group. The first is Todd Humphreys from Mechanical and Aerospace Engineering and the second is Brent Ledvina from the School of Electrical and Computer Engineering . The last three authors are: Mark Psiaki Professor Mechanical and Aerospace Engineering, Brady O' Hanlon a current ECE grad student, and myself."
"The article's subject is spoofing of GPS receivers. Spoofing refers to a process of fooling a GPS receiver into accepting one or more false GPS signals that have been generated by a malicious device, the spoofer. The article centers on a new, advanced spoofer that we have developed and tested using real-time software radio technology. This device allows for a new type of sophisticated spoofing attack that is hard to detect. Our aim is to use this device in a sort of "war games" mode as a way of helping us and others to develop improved countermeasures against such attacks. The first two authors have already begun a collaboration with a receiver manufacturer that seeks to evaluate a proposed anti-spoofing system.
