SUMMARY:Computation and Secrecy in Multiterminal Systems
DESCRIPTION:Speaker: Himanshu Tyagi (Department of Electrical and Computer 
 Engineering\nand Institute for Systems Research\nUniversity of Maryland\nC
 ollege Park\, MD 20742\nUnited States of America)\n\nAbstract: \nInformati
 on theoretic secrecy provides a framework for exploring schemes that guara
 ntee provable unconditional security in network systems. This talk explor
 es innate structural connections that exist between the information theore
 tic notion of multiterminal secrecy on the one hand and data compression a
 nd function computation on the other. For a setup where multiple terminals
  observe separate but correlated data and communicate over a public channe
 l\, three classes of secrecy problems are studied: (i) generating secret k
 eys\, (ii) ensuring secrecy against a querying eavesdropper\, and (iii) se
 cure function computation over an insecure communication network. The afor
 ementioned connections lead to new results and algorithms for all of these
  problems. Applications abound\, including in biometric security\, hardwar
 e security\, cloud computing and in-network computation in sensor networks
 . This talk is based on different joint works with Prakash Narayan\, Piyus
 h Gupta\, Navin Kashyap\, Yogesh Sankarasubramaniam and Kapali Viswanathan
 .\n\n\nBiography: Himanshu Tyagi received his Bachelor of Technology degr
 ee in Electrical Engineering and Master of Technology degree in Communicat
 ions and Information Technology\, both from the Indian Institute of Techno
 logy\, Delhi in 2007. His master 's thesis advisor was Prof. Ranjan K. M
 allik. He is currently a doctoral candidate in the Department of Electrica
 l and Computer Engineering at the University of Maryland\, College Park. 
 His Ph.D. advisor is Prof. Prakash Narayan. He has interned at National S
 emiconductors\, Bangalore in 2005\, at Telecommunications Research Center 
 Vienna\, Vienna in 2006 (with Dr. Jossy Sayir)\, at Bell Labs\, New Jerse
 y in 2009 (with Dr. Piyush Gupta)\, and has spent a semester at Alfrèd R
 ènyi Institute of Mathematics in 2010 (with Prof. Imre Csiszár). He is
  a Clark School's Future Faculty Fellow (2010)\, and an ECE Distinguishe
 d Dissertation Fellow (2012) at the University of Maryland\, College Park
 .  Also\, he was a finalist for the best student paper award at the IEEE 
 International Symposium on Information Theory (2010).\n\n\n \n
