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 ...

Magnetic Unclonable Functions Leveraging Remanence and Anhysteretic States

Advanced Functional Materials, EarlyView.
A micrometric array of magnetic pillars provides a stable and unclonable hardware for generating cryptographic keys. From a single device, the ability is demonstrated to produce a 470‐bit key while also offering a reconfigurable mode of operation.

Minimum Round Card-Based Cryptographic Protocols Using Private Operations

Cryptography, 2021
This paper shows new card-based cryptographic protocols with the minimum number of rounds, using private operations under the semi-honest model. Physical cards are used in card-based cryptographic protocols instead of computers to achieve secure ...

A bisimulation method for cryptographic protocols [PDF]

, 1998
Summary: We introduce a definition of bisimulation for cryptographic protocols. The definition includes a simple and precise model of the knowledge of the environment with which a protocol interacts. Bisimulation is the basis of an effective proof technique, which yields proofs of classical security properties of protocols and also justifies certain ...

Unambiguous Quantum State Discrimination in a PT$\mathcal {PT}$‐Symmetric System of a Single Trapped Ion

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

Multi‐Level Optical Physical Unclonable Function Based on Random Surface Scattering for Hierarchical Cryptographic Protocols

Advanced Science, EarlyView.
This study proposed physical unclonable function based multi‐level key space generation scheme. By exploiting speckle characteristic, a size‐controllable structure is achieved and that is suitable foundation for multiple key extraction. The flexible key space supports various specifications for advanced applications, such as hierarchical authentication

Practical Quantum Bit Commitment Protocol Based on Quantum Oblivious Transfer

Applied Sciences, 2018
Oblivious transfer (OT) and bit commitment (BC) are two-party cryptographic protocols which play crucial roles in the construction of various cryptographic protocols. We propose three practical quantum cryptographic protocols in this paper.
