“…In addition, memristor-based PUFs are also predicted to offer more resistance to model building attacks than purely CMOS-based PUF circuits, since memristors are bidirectional devices, while MOSFET is a unidirectional device [23]. Simulation based studies of memristor PUF circuits have demonstrated that they are capable of achieving close-to-ideal values for the statistical performance metrics, which are often superior compared to the values attained by CMOS-only PUF circuits [20,21].…”

“…There are two main ideas behind using memristors as PUF circuits, and the protocols built around them: write-time based output response variation [20][21][22] and variation of output voltages in memristor-based crossbar "polynominoes" [7,23,24]. We describe these two schemes in detail below.…”

“…Leveraging the intrinsic controlled sensitivity to processvariation effects, memristor-based circuits (usually in a hybrid form combined with CMOS) has been proposed to operate as hardware security primitives, particularly as PUF circuits [7,[20][21][22][23][24]]. The combination is made possible by the fact that the memristor manufacturing technology is compatible with modern CMOS fabrication standards [22], which provides memristors a distinct advantage compared to many other nano-devices.…”

“…Apart from SRAM PUFs, there are other types of weak PUFs were proposed which were either still based on memory or non-memory. Examples of PUFs that are based on the memory design characteristics are Flash [27], DRAM [28] and Memristors [29]. As for the non-memory PUFs, Kumar et al [30] proposed the butterfly PUF which utilizes the cross-coupled latches in FPGAs while Simons et al [31] developed a PUF which is based on bus keepers as an alternative to D Flip-Flop PUF.…”

Abstract-Security component in IoT system are very crucial because the devices within the IoT system are exposed to numerous malicious attacks. Typical security components in IoT system performs authentication, authorization, message and content integrity check. Regarding authentication, it is normally performed using classical authentication scheme using crypto module. However, the utilization of the crypto module in IoT authentication is not feasible because of the distributed nature of the IoT system which complicates the message cipher and decipher process. Thus, the Physical Unclonable Function (PUF) is suggested to replace crypto module for IoT authentication because it only utilizes responses from set of challenges instead of cryptographic keys to authenticate devices. PUF can generate large number of challenge-response pairs (CRPs) which is good for authentication because the unpredictability is high. However, with the emergence of machine learning modeling, the CRPs now can be predicted through machine learning algorithms. Various defense mechanisms were proposed to counter machine learning modeling attacks (ML-MA). Although they were experimentally proven to be able to increase resiliency against ML-MA, they caused the generated responses to be instable and incurred high area overhead. Thus, there is a need to design the best defense mechanism which is not only resistant to ML-MA but also produces reliable responses and reduces area overhead. This paper presents an analysis on defense mechanisms against ML-MA on strong PUFs for IoT authentication.

This paper proposes novel secret key generation techniques using memristor devices. The approach depends on using the initial profile of a memristor as a master key. In addition, session keys are generated using the master key and other specified parameters. In contrast to existing memristor-based security approaches, the proposed development is cost effective and power efficient since the operation can be achieved with a single device rather than a crossbar structure. An algorithm is suggested and demonstrated using physics based Matlab model. It is shown that the generated keys can have dynamic size which provides perfect security. Moreover, the proposed encryption and decryption technique using the memristor based generated keys outperforms Triple Data Encryption Standard (3DES) and Advanced Encryption Standard (AES) in terms of processing time. This paper is enriched by providing characterization results of a fabricated microscale Al/TiO2/Al memristor prototype in order to prove the concept of the proposed approach and study the impacts of process variations. The work proposed in this paper is a milestone towards System On Chip (SOC) memristor based security.
