Rocking Drones with Sound Interference


Yongdae Kim

Monday, August 10, 2015
2:00 p.m.

Keller Hall 3-125

Continuous sensing-and-actuation systems such as implantable medical devices, self-driving car or drone draw a lot of attention these days. Existing security research on these devices still focuses traditional problems: 1) getting root permission? or 2) blocking or spoofing communication channel. This talk focuses on exploiting sensing channels. In the first part of the talk, I will define sensing channels and introduce a few previously known mechanisms to exploit these sensing channels. The second part of the talk focuses on incapacitating drones using sound interference. This is possible because MEMS gyroscope sensors used in drones have resonant frequencies. We will show that playing sound will affect sensing output of gyroscopes, which in turn complicates their flight control system. We will also discuss limitation as well as defense against this attack.


Yongdae Kim is a KAIST Chair Professor in the Department of Electrical Engineering and an affiliate professor in the GSIS at KAIST. He received PhD degree from the computer science department at the University of Southern California under the guidance of Gene Tsudik. Between 2002 and 2012, he was an associate/assistant professor in the Department of Computer Science and Engineering at the University of Minnesota - Twin Cities. Before joining U of Minnesota, he worked as a research staff for two years in Sconce Group in UC Irvine. Before coming to the US, he worked 6 years in ETRI for securing Korean cyberinfrastructure. He received NSF career award on storage security and McKnight Land-Grant Professorship Award from University of Minnesota in 2005. Currently, he is serving as a steering committee member of NDSS and associate editor for ACM TISSEC. His current research interests include security issues for various systems such as cyber physical systems, social networks, cellular networks, P2P systems, medical devices, storage systems, mobile/ad hoc/sensor networks, and anonymous communication systems.
