“…The output from the MUX undergoes XORing and character padding operations to produce the response. The MA-PUF (Mixed Arbiter-PUF) generates a response by integrating an additional two 4-1 MUX with four switch blocks between the switch block and the arbiter to reduce the resilience against modeling attacks [93]. The drawback of Spenke et al [64] proposal is that it cannot be utilized to authenticate a time-critical system, due to the fact that along with the selected APUF configuration file, the challenges to FPGA also are needed to be sent.…”

Hardware security modules play a crucial role in protecting and preserving technologically integrated systems that are used in daily life. They employ cryptographic protocols to secure a system against adversaries. Generally, cryptographic algorithms and security keys are quintessential for maintaining the security of a system. Cryptography uses a secret key to encipher and decipher the data. These secret keys are stored in a non-volatile memory that attackers can easily access. The hardware security primitive, Physical Unclonable Function (PUF) is a promising alternative for enhancing the security of interconnected devices. A PUF produces an output in response to an input based on physical structure and intrinsic manufacturing variations of an integrated circuit (IC). The generated random response being unpredictable, act as a robust secret key in cryptographic protocols. The first silicon PUF is the Arbiter PUF, which can instantly produce significantly more secret keys based on the input with a lightweight design. Due to its advantage, it is best suited for device authentication in resource-constrained applications employing the Internet of Things (IoT). The PUF is also suitable for applications such as the Internet of Vehicles, the Internet of Medical Things, RFID tags, and smart cards. In this paper, the basic Arbiter PUF design is implemented in ZedBoard to analyze the PUF performance characteristics for 16, 32, and 64-bit responses. A review of Arbiter PUF design, different compositions of Arbiter PUF, their individual characteristics, and vulnerabilities against machine-learning attacks have been presented at their broader best in this paper.

An emerging technology known as Physical unclonable function (PUF) can provide a hardware root-of-trust in building the trusted computing system. PUF exploits the intrinsic process variations during the integrated circuit (IC) fabrication to generate a unique response. This unique response differs from one PUF to the other similar type of PUFs. Static random-access memory PUF (SRAM-PUF) is one of the memory-based PUFs in which the response is generated during the memory power-up process. Non-volatile memory (NVM) architecture like SRAM is available in off-the-shelf microcontroller devices. Exploiting the inherent SRAM as PUF could wide-spread the adoption of PUF. Therefore, in this study, we evaluate the suitability of inherent SRAM available in ATMega2560 microcontroller on Arduino platform as PUF that can provide a unique fingerprint. First, we analyze the start-up values (SUVs) of memory cells and select only the cells that show random values after the power-up process. Subsequently, we statistically analyze the characteristic of fifteen SRAM-PUFs which include uniqueness, reliability, and uniformity. Based on our findings, the SUVs of fifteen on-chip SRAMs achieve 42.64% uniqueness, 97.28% reliability, and 69.16% uniformity. Therefore, we concluded that the available SRAM in off-the-shelf commodity hardware has good quality to be used as PUF.
