Physical Unclonable Functions as Security Enablers

Three minute talk on how Physical Unclonable Functions (PUFs) can act as security enablers in Machine-to-Machine (M2M) or Internet of Things (IoT) scenarios.
Presented in the TRUDEVICE Training School in April 2016 at Leukerbad, Switzerland.

3. 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
