“…Gu et al [ 122 ] and Schaub et al [ 123 ] used entropy to evaluate the randomness of PUFs. Similarly, Koyily et al [ 124 ] used entropy to evaluate the non-linearity of PUFS. Upper bounds on the entropy of some types of PUFs were calculated by Delvaux et al [ 21 ].…”

After being introduced by Shannon as a measure of disorder and unavailable information, the notion of entropy has found its applications in a broad range of scientific disciplines. In this paper, we present a systematic review on the applications of entropy and related information-theoretical concepts in the design, implementation and evaluation of cryptographic schemes, algorithms, devices and systems. Moreover, we study existing trends, and establish a roadmap for future research in these areas.

“…According to Jefferson Capovilla, Mario Cortes, Guido Arauj [19] proposed a 32 stage tri-state buffer based arbiter circuit simulated using SPICE AMS 350nm technology, described different types of delay design network (Gate drive strength, Gate sizing) techniques as well as arbiter design techniques to improve the delay variability of the PUF,From the statistical results authors found that use of weak gates can improve the delay variability by a factor of four and instead of SR latch based arbiter D-FF arbiter should improve the Hamming Weight Distribution of a PUF. Anoop Koyily,Chen Zhou [20] proposed a technique in order to measure the PUF metrics accurately using Shannon entropy to determine whether PUF is linear or non linear, applied to linear, Feed-Forward, Modified-Feed Forward 32 bit PUF architectures (experiments done on IBM32nm HKMG technology) and observed almost 100% sensitivity and specificity [20].the delay of the any arbiter PUF architecture were mainly depends on the device geometry and number of stages. Hence as scaling down the technology that leads to a rapid variations in device geometry and which helps to enhance the security features of PUF architectures.…”

Recent fourth industrial revolution, industry4.0 results in lot of automation of industrial processes and brings intelligence in many home appliances in the form of IoT, enhances M2M / D2D communication where electronic devices play a prominent role. It is very much necessary to ensure security of those devices. To provide reliable authentication and identification of each device and to abort the counterfeiting from the unauthorized foundries Physical Unclonable Functions (PUFs) emerged as a one of the promising cryptographic hardware security solution. PUF is function, mathematically modeled by using uncontrollable/ unavoidable random variances of the fabrication process of the ICs. These variances can generate unpredictable, random responses can be used to overcome the difficulties such as storing the keys in non-volatile memories (NVMs) in the classical cryptography. A wide variety of PUF architectures such as Arbiter PUFs, Ring oscillator PUFs, SRAM PUFs proposed by authors. But due to its design complexity and low cost, Delay based Arbiter PUFs (D-PUFs) are considering to be a one of the security primitives in authentication applications such as low-cost IoT devices for secure key generation. This paper presents a review on the different types of Delay based PUF architectures proposed by the various authors, sources to exhibit the physical disorders in ICs, methods to estimate the Performance metrics and applications of PUF in different domains.
