There has been a great deal of excitement in recent years concerning the evolution of sensor webs. At Berkeley there have now been over six generation of “motes” for these sensor webs, and several new start ups have arisen to commercialize these developments. The primary use of sensor networks to date has been on information gathering and threshold detection. However, it is fair to say that the greatest impact of sensor webs will be from what we call Action Webs, involving “closing the loop” around these networked embedded systems. We believe that this closing the loop brings into sharp focus the real time constraints issues inherent in the use of networked embedded systems. A very large number of societal scale systems such as physical infrastructures, energy and building infrastructures are now being instrumented by these Action Webs. Consequently the use of Action Webs in these Cyber-Physical Systems will need the high confidence attributes of robustness, fault tolerance and resistance to cyber attacks.
In this talk I will provide the rudiments of a theory for modeling confidentiality, integrity and availability attackers on action webs and tools for defending them in depth. Further, we will discuss how we can provide economic incentives to the private entities which own individual action webs to address the issues of “under investment in the common good”. More technically, this is a procedure for helping bridge the gap between the non-cooperative Nash equilibrium of multiple players and the societal optimum strategy. The work is primarily based on the doctoral dissertation of Dr. Saurabh Amin and joint work with Dr. Galina Schwartz.
Shankar Sastry is currently the Dean of the College of Engineering at the University of California, Berkeley (UC Berkeley). He was the Chairman, Department of Electrical Engineering and Computer Sciences, UC Berkeley, from 2001 to July 2004. Until August 2007, he was the Director of the Center for Information Technology Research in the Interest of Society (CITRIS). He served as Director of the Information Technology Office at DARPA from 1999 to 2001. From 1996 to 1999, he was the Director of the Electronics Research Laboratory at Berkeley. He received his B.Tech. from the Indian Institute of Technology, Bombay, 1977, M.S. in EECS, M.A. in Mathematics and Ph.D. in EECS from UC Berkeley, 1979, 1980, and 1981, respectively. His numerous honors include a membership in the National Academy of Engineering, Fellow of the IEEE, an NSF Presidential Young Investigator Award and the Eckman Award of the American Automatic Control Council. He also received the President of India Gold Medal, the IBM Faculty Development Award, an honorary degree from Harvard and the distinguished alumnus award of the Indian Institute of Technology in 1999. In 2010, he received the Asian Pacific Fund\'s Chang-Lin Tien Education Leadership Award.
