Cryptographic protocols with everyday objects [PDF]
Formal Aspects of Computing, 2014 Abstract Most security protocols appearing in the literature make use of cryptographic primitives that assume that the participants have access to some sort of computational device. However, there are times when there is need for a security mechanism to evaluate some result without leaking sensitive information, but computational devices are ...

Advanced Materials, EarlyView.A novel three‐terminal PeLET device vertically integrated through a permeable electrode expands additional functionality beyond conventional two‐terminal devices. the specific mechanism is elucidated of E‐field penetration from the integrated capacitor unit to the LED via transient electroluminescence measurements. The PeLET device enables dual‐channel

Oblivious Transfer based on Key Exchange
, 2007 Key-exchange protocols have been overlooked as a possible means for implementing oblivious transfer (OT). In this paper we present a protocol for mutual exchange of secrets, 1-out-of-2 OT and coin flipping similar to Diffie-Hellman protocol using the ...

Classical Cryptographic Protocols in a Quantum World [PDF]
International Journal of Quantum Information, 2011 Cryptographic protocols, such as protocols for secure function evaluation (SFE), have played a crucial role in the development of modern cryptography. The extensive theory of these protocols, however, deals almost exclusively with classical attackers.

Advanced Science, EarlyView.An unambiguous quantum state discrimination for two nonorthogonal states is demonstrated using a single ion. By implementing a non‐Hermitian Hamiltonian with parity‐time‐reversal (PT) symmetry, two candidate states evolve with different speed and become orthogonal at specific time, hence can be discriminated unambiguously. Experiments are performed for

On the Design of Cryptographic Primitives
, 2010 The main objective of this work is twofold. On the one hand, it gives a brief overview of the area of two-party cryptographic protocols. On the other hand, it proposes new schemes and guidelines for improving the practice of robust protocol design.

Advanced Intelligent Discovery, EarlyView.Memristors based on trimethylsulfonium (phenanthroline)tetraiodobismuthate have been utilised as a nonlinear node in a delayed feedback reservoir. This system allowed an efficient classification of acoustic signals, namely differentiation of vocalisation of the brushtail possum (Trichosurus vulpecula).

Statistical Link Between Bell Nonlocality and Uncertainty Relations in Quantum Mechanics
Annalen der Physik, EarlyView.Bell nonlocality and uncertainty principle are two distinguished features in quantum mechanics from classical physics. In this work, it is showed the interplay between these two quantum properties. The upper bound of nonlocal correlation strength is determined by accumulation of all local measurement uncertainty, which means that more Bell nonlocality ...
