Ultra-Low Power Oscillator Collapse Physical Unclonable Function Based on FinFET

Abstract: The main purpose of this paper is to achieve ultra-low power Physical Unclonable Function (PUF) to meet the requirements for Internet of Things (IoT) applications. PUFs are promising hardware security primitives that are based on the uniqueness and the unclonability of the device's physical characteristics to provide a unique identifier for devices. PUFs can be used in device authentication and for secure key storage and generation. This paper presents Oscillator Collapse Physical Unclonable Function (OC-PUF),… Show more

“…Figure 5 illustrates the typical physical phenomena that generate static entropy for a PUF application. Commonly, static entropy is obtained by the process variation of the implementation, which causes alterations in the frequency response in ring oscillators (ROs) [36,37] and the time of frequency collapse in multi-modal RO [38,39]. However, external circuits are necessary for collecting the static entropy.…”

“…As a result, the gate is unable to shut off the channel completely in the off-mode of operation, which leads to an increased Ioff between the drain and the source [39]. Very limited work on employing FinFET-based PUF has reported, such as FinFET-based hybrid ring arbiter PUF [40] and oscillator collapse and time collapse comparator PUFs [41].…”
