Anti-counterfeiting: Mixing the Physical and the Digital World

In this paper, we overview a set of desiderata for building digital anti-counterfeiting technologies that rely upon the difficulty of manufacturing randomized complex 3D objects. Then, we observe how this set is addressed by RF-DNA, an anti-counterfeiting technology recently proposed by DeJean and Kirovski. RF-DNA constructs certificates of authenticity as random objects that exhibit substantial uniqueness in the electromagnetic domain

Physically Unclonable Functions: A Study on the State of the Art and Future Research Directions

The idea of using intrinsic random physical features to identify objects, sys-tems and people is not new. Fingerprint identification of humans dates at least back to the nineteenth century [20] and led to the field of biometrics. In the eighties and nineties of the twentieth century, random patterns in pa
