Security Analysis of Sending or Not-Sending Twin-Field Quantum Key Distribution with Weak Randomness [PDF]

open access: yesEntropy, 2022
Sending-or-not sending twin-field quantum key distribution (SNS TF-QKD) has the advantage of tolerating large amounts of misalignment errors, and its key rate can exceed the linear bound of repeaterless quantum key distribution.

Weak Randomness Analysis of Measurement-Device-Independent Quantum Key Distribution with Finite Resources

open access: yesPhotonics, 2022
The ideal quantum key distribution (QKD) protocol requires perfect random numbers for bit encoding and basis selecting. Perfect randomness is of great significance to the practical QKD system. However, due to the imperfection of practical quantum devices,

Security analysis of measurement-device-independent quantum conference key agreement with weak randomness

open access: yesFrontiers in Physics, 2023
Quantum conference key agreement (QCKA) allows multiple users to distribute secret conference keys over long distances. Measurement-device-independent QCKA (MDI-QCKA) is an effective QCKA scheme, which closes all detection loopholes and greatly enhances ...

Realistic noise-tolerant randomness amplification using finite number of devices [PDF]

open access: yesNature Communications, 2016
Quantum mechanics allows to generate nearly ideal random strings from initially weak random sources, important for security of data systems, but this remains elusive in practice.

Weak randomness in device-independent quantum key distribution and the advantage of using high-dimensional entanglement

open access: yesPhysical Review A, 2013
We show that in device independent quantum key distribution protocols the privacy of randomness is of crucial importance. For sublinear test sample sizes even the slightest guessing probability by an eavesdropper will completely compromise security.

Private Weakly-Random Sequences from Human Heart Rate for Quantum Amplification

open access: yesEntropy, 2021
We investigate whether the heart rate can be treated as a semi-random source with the aim of amplification by quantum devices. We use a semi-random source model called ε-Santha–Vazirani source, which can be amplified via quantum protocols to obtain a ...

Novel hybrid strong and weak PUF design based on FPGA

open access: yes网络与信息安全学报, 2021
Physically unclonable function (PUF) can produce intrinsic keys with characteristics of randomness, uniqueness and tamper-proof by exploiting the process deviations which can not be avoided in the chip manufacturing process.A novel hybrid strong and weak

An Efficient Double Parameter Elliptic Curve Digital Signature Algorithm for Blockchain

open access: yesIEEE Access, 2021
The classic Elliptic curve digital Signature Algorithm (ECDSA) uses one inversion operation in the process of signature and verification, which greatly reduces the efficiency of digital signatures.

Transport equation driven by a stochastic measure

open access: yesModern Stochastics: Theory and Applications, 2023
The stochastic transport equation is considered where the randomness is given by a symmetric integral with respect to a stochastic measure. For a stochastic measure, only σ-additivity in probability and continuity of paths is assumed.
