Creating digital circuits of ever decreasing size leads to certain imperfections that cannot be avoided. Although these imperfections are not significant enough to hinder the digital circuit operation, they are random and can be exploited to create a unique digital fingerprint which can be used as a chip identity. Unique digital fingerprints can be created on any number of circuits and in our research...
In this paper, we discuss the method of creating a circuit identifier, or digital fingerprint, for field programmable gate arrays (FPGAs). The proposed digital fingerprint is a function of the natural variations in the semiconductor manufacturing process that cannot be duplicated or forged. The proposed digital fingerprint allows the use of any arbitrary of nodes internal to the circuit or the circuit...
