SUMMARY:Protecting Analog Sensor Security - Kevin Fu\, Associate Professor
  in Electrical Engineering and Computer Science\, University of Michigan

DESCRIPTION:Why are undergraduates taught to hold the digital abstraction 
 as sacrosanct and unquestionable?  Why do microprocessors blindly trust in
 put from sensors\, and what can be done to establish trust in unusual inpu
 t channels in cyberphysical systems? Risks of analog sensor security pose 
 challenges to autonomous vehicles\, medical devices\, and the Internet of 
 Things. Analog sensor security builds upon classic research in fault injec
 tion and side channels. Paradoxically\, analog security can reduce risks b
 y detecting an adversary via the physics of computation. I will explain ap
 proaches for computers to distinguish real signals from fake signals\, as 
 well as technology that exploits beneficial side channels in AC power outl
 ets to detect malware. I'll explain modulation attacks based on Ghost Talk
  [Foo Kune et al.\, IEEE S&P] and WALNUT [Trippel et al.\, IEEE Euro S&P] 
 whereby intentional electromagnetic and acoustic interference causes chose
 n failures and unintentional demodulation systems ranging from fitbits and
  implantable medical devices to drones and phones. This work brings some c
 losure to my curiosity on why a cordless phone would ring whenever I execu
 ted certain memory operations on the video graphics chip of an Apple IIGS.
 \n\nBio:\nKevin is Associate Professor in EECS at the University of Michig
 an where he directs the Security and Privacy Research Group (SPQR.eecs.umi
 ch.edu) and the Archimedes Center for Medical Device Security (secure-medi
 cine.org). He was named a Sloan Research Fellow\, MIT Technology Review TR
 35 Innovator of the Year\, and Fed100 Award recipient. He received best pa
 per awards from USENIX Security\, IEEE S&P\, and ACM SIGCOMM. Fu has testi
 fied in the U.S. House and Senate on matters of information security and h
 as written commissioned work on trustworthy medical device software for th
 e U.S. National Academy of Medicine. He is a member the Computing Communit
 y Consortium Council and ACM Committee on Computers and Public Policy. Kev
 in previously served as program chair of USENIX Security\, a member of the
  U.S. NIST Information Security and Privacy Advisory Board\, and a visitin
 g scientist at the U.S. Food & Drug Administration. Fu received his B.S.\,
  M.Eng.\, and Ph.D. from MIT. He earned a certificate of artisanal bread m
 aking from the French Culinary Institute.
