Abstract
ABSTRACT
Physically unclonable functions (PUFs) permit physical devices to function as unclonable security evaluations, as PUF technology is resistant to hardware flaw attacks and serves as distinct fingerprints for electronic devices. Among typical kinds of physically unclonable function (PUF) circuits employing the delay feature is the ring oscillator PUF (ROPUF), which provides the ability to adapt to continuous changes in obtaining non-repetitive and unique secret key outputs by exploiting the advantage of the characteristics of the frequency differences between the ring oscillators in the circuit. This study discusses an architecture employing the nano-technology electronic components, which is the memristor device, specifically the Ag/MoS₂/ZnO/Ti memristor. The utilisation of the memristor comprised a simulation part that approximates the theoretical mechanism of the device using MATLAB to extract the hysteresis loop of the memristor model, which is considered as the signature for memristor behaviour. After converting voltage/current values from analog to digital values, then the obtained output will be considered for the ROPUF circuit as input (challenge). Field programmable gate array (FPGA) platforms are adopted to implement memristive-PUF security architecture, which includes memristor-based ring oscillators to extract an irreversible secret key that satisfies all security standards. Furthermore, this study investigates the improvement in performance metrics such as uniqueness, uniformity, bitaliasing, and reliability, which are achieved by the following percentages, respectively. For different FPGA devices, such as the (Spartan-3), the resulting measures were achieved: 48.55%, 49.17%, 47.54%, and 98.22%. As for the (Spartan-6) device, the results were extracted as 48.78%, 48.11%, 48.87%, and 99.13%. Also, for (Altera Cyclone II), the results were 47.34%, 47.59%, 46.91%, and 97.42%.
The thesis has been accepted as fulfilling the requirements for the Master's degree.
