“…It effectively utilizes the available circuit resources which otherwise would have been unused, because the implementation of a simple RO with five to seven delay elements will still occupy a complete CLB. In this way redundancy is achieved with a 100% resource utilization compared to the 1-out-of-k method [1] and the method of averaging [17].…”

“…Though this technique is novel, manipulating transistor level parameter like reverse body biasing is not trivial in FPGAs. Yu et al proposed a technique to reduce noise in RO-PUF responses [17]. They use averaging of RO frequencies along with a thresholding mechanism to select a stable response bit.…”

Abstract.In this paper, we analyze ring oscillator (RO) based physical unclonable function (PUF) on FPGAs. We show that the systematic process variation adversely affects the ability of the RO-PUF to generate unique chip-signatures, and propose a compensation method to mitigate it. Moreover, a configurable ring oscillator (CRO) technique is proposed to reduce noise in PUF responses. Our compensation method could improve the uniqueness of the PUF by an amount as high as 18%. The CRO technique could produce nearly 100% error-free PUF outputs over varying environmental conditions without post-processing while consuming minimum area.

“…Each cell produces a single bit, or occasionally a few bits. This includes memory-based designs, such as the SRAM PUF [16], as well as the coating PUF [25] and a subset of the large number of ring oscillator-based designs, e.g., [29]. The most prominent entropy-degrading effects for such PUFs are bias and spatial correlations.…”

Abstract. The device-unique response of a physically unclonable function (PUF) can serve as the root of trust in an embedded cryptographic system. Fuzzy extractors transform this noisy non-uniformly distributed secret into a stable high-entropy key. The overall efficiency thereof, typically depending on error-correction with a binary [n, k, d] block code, is determined by the universal and well-known (n − k) bound on the min-entropy loss. We derive new considerably tighter bounds for PUFinduced distributions that suffer from, e.g., bias or spatial correlations. The bounds are easy-to-evaluate and apply to large non-trivial codes, e.g., BCH, Hamming and Reed-Muller codes. Apart from an inherent reduction in implementation footprint, the newly developed theory also facilitates the analysis of state-of-the-art error-correction methods for PUFs. As such, we debunk the reusability claim of the reverse fuzzy extractor. Moreover, we provide proper quantitative motivation for debiasing schemes, as this was missing in the original proposals.
