Post-correlation signal analysis to detect spoofing attacks in GNSS receivers [pdf]Paper  doi  abstract   bibtex   
Due to the low level of the received power and to the known signal structure, Global Navigation Satellite Systems (GNSS) civil signals might be vulnerable to different sources of interference. Among them, the spoofing attacks are considered ones of the most deceptive, since their scope is controlling the output of the victim receiver. This paper presents a set of live experiments that validate the performance of a spoofing detection method, based on the Chi-square Goodness of Fit (GoF) test and applied post-correlation. Results are promising and show the GoF test capability to successfully warn the user in case of a spoofing attack.
