Multi-exponentiation (cryptographic protocols) [PDF]

IEE Proceedings - Computers and Digital Techniques, 1994
In several cryptographic protocols the product of a small number of exponentiations is required, but the separate exponentiation results are not needed. A simultaneous exponentiation algorithm that takes advantage of this situation and that is substantially faster than the ordinary approach using separate exponentiations is presented.

Cylindrical Vector Beam Multiplexing based on All‐Dielectric Fiber Meta‐Tips Enabling High‐Capacity Bidirectional Optical Communication

Laser &Photonics Reviews, EarlyView.
Cylindrical vector beam (CVB) multiplexing offers a viable solution to channel capacity, integration, and unidirectional transmission challenges in fiber‐rich sixth‐generation backbone networks. An all‐dielectric fiber meta‐tip‐enabled CVB multiplexing system is proposed and demonstrated, providing high‐capacity, bidirectional optical interconnects and

Using of small-scale quantum computers in cryptography with many-qubit entangled states

, 2004
We propose a new cryptographic protocol. It is suggested to encode information in ordinary binary form into many-qubit entangled states with the help of a quantum computer. A state of qubits (realized, e.g., with photons) is transmitted through a quantum

Efficient Robust Spontaneous Parametric Down‐Conversion via Detuning Modulated Composite Segments Designs

Laser &Photonics Reviews, EarlyView.
Detuning modulated composite segmentation (DMCS) enables robust spontaneous parametric down‐conversion with sevenfold improved temperature stability compared to conventional designs, opening new possibilities for stable quantum photon sources. ABSTRACT Spontaneous parametric down conversion (SPDC) holds a pivotal role in quantum physics, facilitating ...

How to Formalize Loop Iterations in Cryptographic Protocols Using ProVerif

IEEE Access
The formal verification of cryptographic protocols has been extensively studied in recent years. To verify the cryptographic protocol security, formal verification tools consider protocol properties as interactive processes involving a cryptographic ...

Composable security in relativistic quantum cryptography

New Journal of Physics, 2019
Relativistic protocols have been proposed to overcome certain impossibility results in classical and quantum cryptography. In such a setting, one takes the location of honest players into account, and uses the signalling limit given by the speed of light

Functional and phylogenetic beta diversity response of nocturnal moth assemblages to land‐use intensity in grasslands and forests

Oikos, EarlyView.
Land‐use intensification is filtering for species, able to cope with anthropogenic landscapes. This was assumed to result in functionally and phylogenetically homogenous communities, but a recent meta‐analysis could not confirm a consistent homogenization response to human pressure and raises open questions.

Statistical Complexity of Quantum Learning

Advanced Quantum Technologies, EarlyView.
The statistical performance of quantum learning is investigated as a function of the number of training data N$N$, and of the number of copies available for each quantum state in the training and testing data sets, respectively S$S$ and V$V$. Indeed, the biggest difference in quantum learning comes from the destructive nature of quantum measurements ...

A Probabilistic Scheduler for the Analysis of Cryptographic Protocols

Electronic Notes in Theoretical Computer Science, 2007
AbstractWhen modelling cryto-protocols by means of process calculi which express both nondeterministic and probabilistic behavior, it is customary to view the scheduler as an intruder. It has been established that the traditional scheduler needs to be carefully calibrated in order to more accurately reflect the intruder's capabilities for controlling ...

Accreditation Against Limited Adversarial Noise

Advanced Quantum Technologies, EarlyView.
An upgraded accreditation (a variant of quantum verification) scheme is presented, significantly relaxing the assumptions, to allow adversarial noise, while preserving the suitability for near‐term / immediate usage. Abstract An accreditation protocol (a variety of quantum verification) is presented, where error is assumed to be adversarial (in ...
