LPN-based Device Authentication Using Resistive Memory

Recent progress in the design and implementation of resistive memory components such as RRAMs and PCMs has introduced opportunities for developing novel hardware security solutions using unique physical properties of these devices. In this work, we utilize the faults in HfOx-based resistive RRAMs to design secure, lightweight device authentication protocols. To detail our design, first, we introduce the device breakdown problem due to high bias conditions in resistive memory and the physics behind non-recoverable resistive states. Then, using the concepts of learning with parity noise (LPN) based authentication protocols, we demonstrate that simple READ and WRITE operations on resistive memory cells with defects can perform necessary calculation required for LPN-based authentication schemes. Next, we design two simple authentication protocols using resistive memory based hardware and provide a detailed security analysis for these protocols. We find that these authentication mechanisms can offer significant improvement against its CMOS counterpart regarding the area and power budget. Finally, we provide detailed physical design requirements for the memory components. The resistive memory components that are capable of performing the proposed authentication protocols have also been designed and fabricated. From our analysis, we find that these memory dependent authentication protocols are lightweight, resistant to learning attacks from active and passive adversaries, and reliable under normal changes in operating conditions.
