Physical Unclonable Functions • Accept challenge and produce unique response • Based on intrinsic characteristics which are unclonable and difficult to model • Responses used as cryptographic keys, random numbers or unique identifiers • Offline attacks are impossible • Intrusive attacks would destroy the secret before exposing it Konstantinos Goutsos TRUDEVICE Training School, April 2016, Leukerbad, CH PUFs as security enablers 3 / 4
