Random pn-junctions for physical cryptography
Applied Physics Letters, 2010In this paper, we report on high-rectification pn-diodes (rectification ratios up to 2×107) prepared by aluminum-induced crystallization on crystalline Si-wafers, which exhibit highly random I(V) characteristics. We argue that arrays of such diodes can be employed as physical uncloneable functions for cryptography.

Application of mismatched Cellular Nonlinear Networks for Physical Cryptography
2010 12th International Workshop on Cellular Nanoscale Networks and their Applications (CNNA 2010), 2010This paper proposes the use of Cellular Non-Linear Networks (CNNs) as physical uncloneable functions (PUFs). We argue that analog circuits offer higher security than existing digital PUFs and that the CNN paradigm allows us to build large, unclonable, and scalable analog PUFs, which still show a stable and repeatable input-output behavior.

Benefits of Physical Layer Security to Cryptography: Tradeoff and Applications
2019 IEEE International Black Sea Conference on Communications and Networking (BlackSeaCom), 2019Physical-layer security (PLS) has raised the attention of the research community in recent years, particularly for Internet of things (IoT) applications. Despite the use of classical cryptography, PLS provides security at physical layer, regardless of the computational power owned by the attacker.

Physical Layer Cryptography and Cognitive Networks
Wireless Personal Communications, 2011Recently the huge development of different and heterogeneous wireless communication systems raises the problem of growing spectrum scarcity. Cognitive radio tends to solve this problem by dynamically utilizing the spectrum. Security in cognitive radio network becomes a challenging issue, since more chances are given to attackers by cognitive radio ...

Encrypted Decentralized Multi-Agent Optimization for Privacy Preservation in Cyber-Physical Systems
IEEE Transactions on Industrial Informatics, 2023Decentralized optimizations have been extensively applied in large-scale industrial cyber-physical systems to achieve control scalability. However, state-of-the-art methods heavily depend on explicit communications between participants, exposing the ...

RFID Security: Cryptography and Physics Perspectives
2008In this chapter, we provide an overview of mechanisms that are cheap to implement or integrate into RFID tags and that at the same time enhance their security and privacy properties. We emphasize solutions that make use of existing (or expected) functionality on the tag or that are inherently cheap and thus enhance the privacy friendliness of the ...

Physical layer security: All-optical cryptography in access networks
2008 10th Anniversary International Conference on Transparent Optical Networks, 2008The physical layer security of passive optical networks (PON) is investigated within a rigorous cryptoanalysis framework; we consider different threats and confidentiality attacks and propose different secure optical code division multiple access (OCDMA)-based architectures.
