“…10 These categories and their importance to resource-constraint IoT networks are explained as follows. [10][11][12][13] In NIST post-quantum cryptography standardization, 23 signature and 59 encryption schemes were submitted in the initial round at the end of 2017. Out of these 82 schemes, 69 schemes were found to be complete and proper.…”

Traditional and lightweight cryptography primitives and protocols are insecure against quantum attacks. Thus, a real-time application using traditional or lightweight cryptography primitives and protocols does not ensure full-proof security. Post-quantum cryptography is important for the internet of things (IoT) due to its security against quantum attacks. This paper offers a broad literature analysis of post-quantum cryptography for IoT networks, including the challenges and research directions to adopt in real-time applications.The work draws focus towards post-quantum cryptosystems that are useful for resource-constraint devices. Further, those quantum attacks are surveyed, which may occur over traditional and lightweight cryptographic primitives.

“…The optical medium plays the role of a token, which is technologically hard to clone and it can produce a large number of independent, almost truly random keys, each one associated with different parameters of the input laser light (e.g., wavelength, power, wavefront, angle of incidence, etc.). Following the work of Pappu et al, PUFs have attracted considerable attention over the last two decades or so, and the related literature is rather rich [26][27][28][29][30][31][32][33]. Currently, there are different types of PUFs, including optical (non-silicon) PUFs, time-delay-based silicon PUFs, intrinsic silicon PUFs, magnetic PUFs, etc.…”

Quantum key distribution protocols allow two honest distant parties to establish a common truly random secret key in the presence of powerful adversaries, provided that the two users share a short secret key beforehand. This pre-shared secret key is used mainly for authentication purposes in the post-processing of classical data that have been obtained during the quantum communication stage, and it prevents a man-in-the-middle attack. The necessity of a pre-shared key is usually considered to be the main drawback of quantum key distribution protocols, and it becomes even stronger for large networks involving more than two users. Here, we discuss the conditions under which physical unclonable functions can be integrated in currently available quantum key distribution systems in order to facilitate the generation and the distribution of the necessary pre-shared key with the smallest possible cost in the security of the systems. Moreover, the integration of physical unclonable functions in quantum key distribution networks allows for real-time authentication of the devices that are connected to the network.

“…Physical unclonable functions (PUFs) based on optical multiple scattering media have attracted considerable attention over the last decades, mainly because they are considered to pave the way for the development of novel more robust cryptographic protocols [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]. The optical multiple scattering medium essentially serves as a token, and the internal disorder renders its cloning a formidable technological challenge.…”

We address the question of whether the presence of Kerr nonlinearity in multiple-scattering optical media offers any advantage with respect to the design of physical unclonable functions. Our results suggest that under certain conditions, nonlinear physical unclonable functions can be more robust against the potential cloning of the medium relative to their linear counterparts that have been exploited in the context of various cryptographic applications.
