One of the emerging technologies for cryptographic key storage is hardware intrinsic security based on Physical Unclonable Functions (PUFs); a PUF is a physical structure of a device that is hard to clone due to its inherent, device-unique and deep-submicron process variations. SRAM PUF is an example of such technology that is becoming popular. So far, only a little is published about modeling and analysis of their Start-Up Values (SUVs). Reproducing the same start-up behavior every time the chip is powered-on is crucial to produce the same cryptographic key.
