ideo\nSpeaker: \nDr. Keshab Parhi\, Edgar F. Johnson Professor of Electro
nic Communication\, Distinguished McKnight University Professor\, Univer
sity of Minnesota\nAbstract:\nThis talk will present approaches to functio
nal obfuscation where the functionality is hidden by incorporating keys to
a design such that the circuit only functions correctly if the key is cor
rect. Various modes are introduced such that only the correct key triggers
the correct functionality of the chip. One goal is to prevent foundries f
rom manufacturing excess parts and third party vendors from selling in bla
ck market. Another goal is to prevent theft of intellectual property. A th
ird goal of obfuscation is to prevent reverse engineering. I will introduc
e the notions of fixed and dynamic obfuscation. We will show that the time
to find the key by trial and error can be increased exponentially with re
spect to the number of key bits with dynamic obfuscation. In the second pa
rt of the talk\, I will discuss chip authentication using physical unclona
ble functions (PUFs). These are small circuits that can exploit manufactur
ing process variations to generate unique signatures of chips. These uniqu
e signatures\, in the form of challenge-response pairs\, can be stored in
a server and can be used to authenticate devices. Various delay-based PUFs
include multiplexer (MUX) PUF and ring-oscillator PUF. I will talk about
modeling both linear and nonlinear MUX PUFs. We will show that both hard a
nd soft responses of linear and nonlinear MUX PUFs can be modeled by artif
icial neural network. I will then talk about XOR PUFs and feed-forward XOR
PUFs that are more secure and attack resistant. I will briefly mention on
going research on accelerators for homomorphic encryption.\nSpeaker Bio:\n
\n\nKeshab K. Parhi received the Ph.D. degree in EECS from the University
of California\, Berkeley\, in 1988. He has been with the University of Min
nesota\, Minneapolis\, since 1988\, where he is currently Distinguished Mc
Knight University Professor and Edgar F. Johnson Professor in the Departme
nt of Electrical and Computer Engineering. He has published over 650 paper
s\, has authored the textbook VLSI Digital Signal Processing Systems (Wile
y\, 1999) and coedited the reference book Digital Signal Processing for Mu
ltimedia Systems (Marcel Dekker\, 1999). His current research addresses VL
SI accelerators for signal processing and machine learning including deep
learning\, data-driven neuroscience\, hardware security and molecular comp
uting. Dr. Parhi is the recipient of numerous awards including the 2003 IE
EE Kiyo Tomiyasu Technical Field Award\, the 2017 Mac Van Valkenburg award
\, and the 2012 Charles A. Desoer Technical Achievement award. He served a
s the Editor-in-Chief of the IEEE TRANSACTIONS ON CIRCUITS AND SYSTEMS —
PART I (2004-2005 term)\, and was an elected member of the Board of Govern
ors of the IEEE Circuits and Systems society from 2005 to 2007. He is a Fe
llow of IEEE\, ACM\, AAAS\, and NAI.\n\n \n \nZoom Information:\nJoin Zoom
