Security Analysis of Sending or Not-Sending Twin-Field Quantum Key Distribution With Weak Randomness [PDF]
Entropy, 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.

Photonics, 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,

Frontiers 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 ...

Private Weakly-Random Sequences from Human Heart Rate for Quantum Amplification
Entropy, 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
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
IEEE 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.

Weak convergence of random processes with immigration at random times [PDF]
Journal of Applied Probability, 2020 AbstractBy a random process with immigration at random times we mean a shot noise process with a random response function (response process) in which shots occur at arbitrary random times. Such random processes generalize random processes with immigration at the epochs of a renewal process which were introduced in Iksanov et al.

Transport equation driven by a stochastic measure
Modern 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.

Random graphons and a weak Positivstellensatz for graphs [PDF]
Journal of Graph Theory, 2011 AbstractIn an earlier article, the authors proved that limits of convergent graph sequences can be described by various structures, including certain 2‐variable real functions called graphons, random graph models satisfying certain consistency conditions, and normalized, multiplicative and reflection positive graph parameters.

IEEE Access, 2020 Public-key encryption is often used to protect data security/privacy and secure communication in scenarios of cloud computing and edge computing. Related randomness attacks model (RRA) for public-key encryption was motivated by randomness failures.
