Physical Unclonable Function (PUF)

A physical unclonable function (PUF) is a function which produces a device-specific ID from intrinsic and unclonable physical features. Among the different types of PUFs, silicon PUFs use the intrinsic manufacturing variability of silicon-based digital integrated circuits. A number of implementation methods exist for silicon PUFs, such as Arbiter PUF, Ring Oscillator PUF, SRAM PUF, Butterfly PUF, and Glitch PUF. By utilizing silicon PUFs, it is possible to identify each LSI and prevent the distribution of imitative LSIs.

We have developed the quantitative evaluation method for PUF performance, new structure of PUF with high unclonability, and so on. The experiment data and source codes can be downloaded from this page.
