Prof. Kang Shin (Kevin and Nancy O'Connor Professor of Computer Science, and the Founding Director of the Real-Time Computing Laboratory (RTCL) in the Electrical Engineering and Computer Science Department at the University of Michigan)

Component faults, bugs, and malicious attacks can all degrade in, or even prevent semi-autonomous systems (SASs) from, correctly capturing their operation context, which is essential to support critical safety features like emergency braking in an autonomous car. While safety features in modern SASs usually rely on static assignment of control priority, such a design may lead to catastrophic accidents when accompanied with erroneous/compromised control and context estimation.

To mitigate the grave danger of SASs' use of incorrect data for making control decisions and learn from the incidents/crashes of Boeing 737 MAX, we propose CADCA, a novel control decision-maker for SASs, that is designed to operate under sensor/data errors or falsifications as well as malicious/erroneous control inputs with the ultimate goal of resolving conflicting control inputs to ensure safety. Our extensive evaluation (of more than 15,700 test-cases) has shown CADCA to achieve a 98% success rate in preventing the execution of incorrect control decisions caused by component failures and/or malicious attacks in the most common scenarios.

This talk will detail the motivation, design and evaluation of CADCA with semi-autonomous vehicles as a representative SAS. This is joint work with Daniel Chen and Noah Curran.

Speaker's Biography
Kang G. Shin is the Kevin & Nancy O'Connor Professor of Computer Science in the Department of Electrical Engineering and Computer Science, The University of Michigan, Ann Arbor. His current research focuses on QoS-sensitive computing and networking as well as on embedded real-time and cyber-physical systems.

He has supervised the completion of 91 PhDs, and authored/coauthored close to 1,000 technical articles, a textbook and about 60 patents or invention disclosures, and received numerous awards, including 2019 Caspar Bowden Award for Outstanding Research in Privacy Enhancing Technologies, and the Best Paper Awards from the 2011 ACM International Conference on Mobile Computing and Networking (MobiCom’11), the 2011 IEEE International Conference on Autonomic Computing, the 2010 and 2000 USENIX Annual Technical Conferences, as well as the 2003 IEEE Communications Society William R. Bennett Prize Paper Award and the 1987 Outstanding IEEE Transactions of Automatic Control Paper Award. He has also received several institutional awards, including the Research Excellence Award in 1989, Outstanding Achievement Award in 1999, Distinguished Faculty Achievement Award in 2001, and Stephen Attwood Award in 2004 from The University of Michigan (the highest honor bestowed to Michigan Engineering faculty); a Distinguished Alumni Award of the College of Engineering, Seoul National University in 2002; 2003 IEEE RTC Technical Achievement Award; and 2006 Ho-Am Prize in Engineering (the highest honor bestowed to Korean-origin engineers).

He has chaired Michigan Computer Science and Engineering Division for 3 years starting 1991, and also several major conferences, including 2009 ACM MobiCom, and 2005 ACM/USENIX MobiSys. He was a co-founder of a couple of startups, licensed some of his technologies to industry, and served as an Executive Advisor for Samsung Research.
