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.

Grey-Box Cryptography: Physical Unclonable Functions
2006Cryptography is a fundamental component of any information security infrastructure. It allows two parties, a sender and a receiver, to exchange messages in a secure and authentic way. For this goal the parties use a publicly known algorithm that depends on a secret key.

Quantum Cryptography as an Approach for Teaching Quantum Physics
2021Quantum physics is not only a fundamental physical theory but recently it promises big technological advances in the so-called 2nd quantum revolution, especially in quantum information. These advances rely on the basic research done since about 1980 while looking for a clarification of the fundamentals of quantum physics.

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.

Lightweight Cryptography for Cyber-Physical Systems
Cyber-physical systems (CPS) are the next generation of intelligent systems that combine the inherent and comprehensive embedding of communication and control technologies to integrate computational resources with hardware facilities. The CPS modules are more vulnerable to an attacker, raising the possibility of physical attacks that might compromise ...Agni Datta +2 more

Physical security of elliptic curve cryptography
Sécurité physique de la cryptographie sur courbes elliptiques La Cryptographie sur les Courbes Elliptiques (abréviée ECC de l'anglais Elliptic Curve Cryptography) est devenue très importante dans les cartes à puces car elle présente de meilleures performances en temps et en mémoire comparée à d'autres cryptosystèmes asymétriques comme ...openaire +1 more source
Why cryptography should not rely on physical attack complexity
2015Seitdem Mitte der Neunziger Jahre die ersten Seitenkanal- und Fehlerangriffe auf kryptographische Technologien vorgestellt wurden, werden kontinuierlich neue Mög- lichkeiten physikalischer Angriffe erforscht. Der Gefahr, die von diesen Angriffen ausgeht, wird begegnet, indem auf bekannte Angriffe reagiert wird und Gegenmaß- nahmen zum Schutz vor ihnen ...

Lightweight Cryptography and Physically Unclonable Functions for Secure In-Vehicle Communications
Proceedings of the International Conference on Research in Adaptive and Convergent SystemsModern vehicles are complex cyber-physical systems that rely on In-Vehicle networks to coordinate the operation of multiple Electronic Control Units (ECUs). Among the various communication protocols adopted in this domain, the Controller Area Network (CAN) remains the most widespread due to its reliability and performance.
