In CAMOUFLAGE we will use organic spintronic non volatilememories (NVMs) to provide the proof of concept of an anti-tampering, concealable PUF that will provide unmatched security in authentication.
Organic spintronic NVMs have the following key enabling features: (i) their conductivity can be tuned by the application of a voltage pulse; (ii) their conductivity depends on the applied magnetic field; (iii) the dependence of the conductivity on the applied magnetic field can be turned on and off by the voltage pulse in (i); (iv) the baseline conductivity varies randomly between different devices. These characteristics will be combined to fabricate an inexpensive, concealable, anti-tampering PUF.
The devices will be fabricated in small crossbar structures, which can be easily integrated with current CMOS chips. The proof of concept will be carried out on such devices. CAMOUFLAGE will also model, design and simulate PUFs of a size suitable for use in real world situations, to demonstrate their effectiveness and scalability.
