Hacking – not Hijacking – Automobiles Lecture is at 10am and repeats at noon. Dr. Xu will present her research on hacking a car's tire pressure management system – and how her students messed up her car's instrumentation. Dr. Xu's research interests are in the areas of wireless networks, sensor networks, network security and privacy. She has conducted research into the effect of jamming on commodity wireless networks. Her results have led to link-layer jamming detection mechanisms, as well as link-layer defense strategies to repair networks in the presence of radio interference. More recently, she is investigating the privacy issues in various wireless networks.
