摘要：
A Hardware-Embedded Delay PUF (HELP) leverages entropy by monitoring path stability and measuring path delays from core logic macros. HELP incorporates techniques to deal with bias. A unique feature of HELP is that it may compare data measured from different test structures. HELP may be implemented in existing FPGA platforms. HELP may leverage both path stability and within-die variations as sources of entropy.
