Abstract:
Future-generation system-on-chips (SoCs) are going to incorporate heterogeneous technologies. Especially, the technologies that are conducive to the non-von Neumann computing paradigm can mitigate the “memory wall” challenge. The security and privacy of these SoCs is going to be a major concern due to their complex nature of the SoCs. Secure computation is one of the challenges that might require careful consideration, as divulging the information of underlying computations may break the cryptographic implementation. In this work, we present an implementation of a Physical Unclonable Function (PUF) based on resistive random access memory (ReRAM) crossbar. The proposed design satisfies the essential properties of PUF and also exploits the inherently stochastic nature of the ReRAM crossbar rendering it resistant to state-of-the-art machine learning-guided attacks. In terms of area and energy, the proposed design outperforms the results published in the recent literature.
