International Business Machines Assigned Patent for Delay Chain Burn-in for Increased Repeatability of Physically Unclonable Functions
ALEXANDRIA, Va., April 20 -- International Business Machines, Armonk, N.Y., has been assigned a patent (8,159,260) developed by four co-inventors for a "delay chain burn-in for increased repeatability of physically unclonable functions." The co-inventors are Derick Gardner Behrends, Rochester, Minn., Todd Alan Christensen, Rochester, Minn., Travis Reynold Hebig, Rochester, Minn., and Daniel Mark Nelson, Rochester, Minn.
The abstract of the patent published by the U.S. Patent and Trademark Office states: "A circuit and method increases the repeatability of physically undetectable functions (PUFs) by enhancing the variation of signal delay through two delay chains during chip burn-in. A burn-in circuit holds the inputs of the two delay chains at opposite random values during the burn-in process. All the PFETs in the delay chains with a low value at the input will be burned in with a higher turn on voltage. Since the PFETs affected in the two delay chains are driven by opposite transitions at burn-in, alternating sets of delay components in the two delay chains are affected by the burn-in cycle. Under normal operation, both of the delay chains see the same input so only one chain has an increase in delay to achieve a statistically reliable difference in the two delay paths thereby increasing the overall repeatability of the PUF circuit."
The patent application was filed on Oct. 5, 2010 (12/898,044). The full-text of the patent can be found at http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&p=1&u=%2Fnetahtml%2FPTO%2Fsearch-bool.html&r=1&f=G&l=50&co1=AND&d=PTXT&s1=8159260.PN.&OS=PN/8159260&RS=PN/8159260
