|Title||ECE Colloquium (ECE 500): "SECURE PERCEPTION FOR AUTONOMOUS SYSTEMS"|
|Location:||151 Everitt Lab|

My research focuses on a category of attacks that has seen scant treatment in the secure control literature. Like cyber attacks, these attacks are hard to detect and can be executed from a distance, but unlike cyber attacks, they are effective even against control systems whose com- munications networks are secure, and so can be considered a more menacing long-term threat. Moreover, this category is subject to realistic physical (as opposed to questionable artificial) constraints on how y can be manipulated, which offers hope for substantial theoretical progress toward effective attack detection and survival. These are field attacks: attacks on the physical fields—electromagnetic, acoustic, pressure, etc.—measured by system sensors. I’m especially interested in field attacks against control systems performing collision avoidance and precise navigation and timing functions, as these are of special importance to the rise of autonomous vehicles. My students and I in the UT Radionavigation Laboratory have demonstrated the surprising potency of a field attack targeting the GPS sensor of an autonomous helicopter: in a live demonstration the target helicopter became remotely controllable almost as if caught in a tractor beam. More recently, we launched a field attack against the semi-autonomous navi- gation system of an $80M superyacht, driving it several kilometers off course without raising alarms.
