Title: PHYSICAL UNCLONEABLE FUNCTION BASED ANTI-COUNTERFEITING SYSTEM
Abstract:
A device for identifying genuine and counterfeited goods using reconfigurable challenge-response pairs (CRP) based on physical unclonable function (PUF), said device comprising one or more antennae for emitting a number of first electromagnetic signals as challenges to a good and for receiving a number of second electromagnetic signals as responses from the good, both challenge and response forming a challenge-response pair for said good, wherein at least one of the antennae is a wideband antenna, a software defined radio (SDR) unit arranged for emitting said first electromagnetic signal(s) as challenge(s) and arranged for receiving said second electromagnetic signal(s) as response(s), a challenge- response pair evaluation unit for analysing said challenge-response pair(s) and to provide a result acknowledging if the good is genuine or counterfeit.
