With the increase of digital devices, the need for robust authentication mechanisms has become crucial. Traditional methods relying on cryptographic key management are susceptible to various risks, particularly the exposure of keys to interception or theft. As cyber threats evolve, the short-comings of these methods are accentuated, necessitating more secure solutions. Physically Unclonable Functions (PUFs) have emerged as a potential alternative, utilizing inherent hardware variations for device authentication without stored secrets. However, recent studies reveal vulnerabilities in conventional PUF implementations. Simultaneously, there's a growing recognition for authentication mechanisms tailored for quantum devices. This recognition has prompted the exploration of Quantum PUFs (QPUFs), which represent a promising solution to enhance security and reliability, leveraging the unique properties of quantum mechanics. In this paper, we propose a novel approach using QPUFs for device authentication that does not require any quantum communication channel or even quantum memory. We design a quantum circuit to serve as a QPUF, evaluating metrics such as instability, randomness, and uniqueness. Additionally, we devise an authentication scheme that exploits the challenge-response paradigm, taking advantage of the distinctive properties of quantum PUFs. Furthermore, we delineate a threat model to identify and mitigate potential risks associated with the authentication process. By assessing the proposed QPUFs efficacy on real real quantum hardware provided by IBM, this research contributes to the advancement of secure authentication protocols in quantum era.

This work presents a Quantum Computing based Physical Unclonable Functions (PUF) architecture with a novel approach for PUF key generation and noise reduction in noisy Quantum systems. The motivation is to explore the potential of Quantum Computing assisted cybersecurity for Security-by-Design (SbD) of Industrial-Internet-of-Things (IIoT). Internet-of-Things (IoT) in Industry 4.0 can improve efficiency, increase automation, and facilitate intelligent decision making through the integration of edge cloud computing paradigms. However, the lack of standardization of security protocols across IIoT devices can be challenging due to the heterogeneous nature of these devices. In this context, a novel Quantum circuits based PUF design that is built on real Quantum hardware is presented. The proposed QPUF can facilitate security in IIoT by using a Quantum hardware generated PUF key as the device identity. The proposed PUF Design is built using Quantum Hadamard Gate, and Ry gates and has been experimentally demonstrated on IBM Quantum hardware systems. The proposed architecture also supports PUF key generation from Quantum hardware for security applications. Figures-of-merits (FoM) of PUF have been evaluated and presented to demonstrate the robustness of the proposed Quantum PUF for SbD of IIoT.
