Abstract [en]

The Global Position System (GPS) has become nearly mandatory in our daily life,like the Internet. Since it (the part for civilian use) is free, open and accurate,lots of applications have made our life more convenient and more effective, suchas the location-based applications for cell phones, tracking bulldozers, shippingcontainers, etc. GPS is becoming mature and rather accurate, but its securitycan’t be neglected since it is widely used in the world. RF interference can beclassified into: intentional and unintentional interference. There are lots of RF inour surroundings, whose frequency might be close to GPS frequency, could affectthe GPS accuracy, or even sometimes make it unavailable. This project, I analyzetwo types interferences, spoofing and jamming interference. I implement two attacks:a version of Cicada attack, to check how this specific attack affects GPS, and thedistance-deceasing attack, a special type of a relay attack (Early Detect(ED) attackand Late Commit(LC) attack). I find (i) that the Cicada attack, as implemented,is essentially equivalent to jamming, and (ii) how to set up the ED/LC attacks tosucceed (i.e., have low BER).
