SRAM-based Physical Unclonable Functions
Presenter: Daniel Holcomb (UMass Amherst)
This talk presents our research into SRAM-based Physical Unclonable Functions (PUFs). PUFs are circuits that use the inherent process variations of each chip to generate unique identifiers or secret keys. SRAM circuits are well-suited for use in PUFs because SRAM cells are small in area and have a differential structure that is insensitive to common mode noise. The talk will include three distinct approaches to SRAM PUFs: (1) the use of SRAM power-up state as an identifier, (2) the use of minimum data-retention voltages as an identifier, and (3) circuit modifications that enable native challenge-response operation from SRAM. These three approaches are published in IEEE Transactions on Computers 2009, RFIDSec 2012, and CHES 2014, respectively.
Daniel Holcomb is an Assistant Professor of ECE at UMass Amherst. He received B.S and M.S. degrees in ECE from UMass Amherst, and a Ph.D. in EECS from UC Berkeley in 2013; his dissertation topic was formal verification of network-on-chip QoS properties using scalable model checking. In 2014 he was a research fellow at the University of Michigan working with Kevin Fu. His research focuses on methodologies for building secure, reliable, and efficient embedded systems.
