Threshold ring signature: generic construction and logarithmic size instantiation

open access: yesCybersecurity
A ring signature is a variant of normal digital signature and protects the privacy of a specific signer in the sense that a ring signature can be verified, but the signer’s identity can only be traced to a limited set. The concept was further enhanced to

A Lattice-Based Threshold Ring Signature Scheme [PDF]

open access: yes, 2010
In this article, we propose a new lattice-based threshold ring signature scheme, modifying Aguilar's code-based solution to use the short integer solution (SIS) problem as security assumption, instead of the syndrome decoding (SD) problem. By applying the CLRS identification scheme, we are also able to have a performance gain as result of the reduction

Spatiotemporal evolution of radio wave pump-induced ionospheric phenomena near the fourth electron gyroharmonic [PDF]

open access: yes, 2007
On 12 November 2001, the European Incoherent Scatter (EISCAT) high-frequency (HF) radio wave transmitter facility, operating in O-mode at 5.423 MHz with 550 MW effective radiated power, produced artificial optical rings which appeared immediately at ...

Spontaneous rotating vortex rings in a parametrically driven polariton fluid

open access: yes, 2015
We present the theoretical prediction of spontaneous rotating vortex rings in a parametrically driven quantum fluid of polaritons -- coherent superpositions of coupled quantum well excitons and microcavity photons.

Attribute-based alterable threshold ring signature scheme with conspiracy attack immunity

open access: yesTongxin xuebao, 2015
Attribute-based cryptography is a generalization and development of the identity-based cryptography,which extends the identity to a set of attributes.In the attribute-based cryptosystem,different members with the same attributes can form a signature ring

Detection Probability of a Low-Mass Planet for Triple Lens Events: Implication of Properties of Binary-Lens Superposition

open access: yes, 2010
In view of the assumption that any planetary system is likely to be composed of more than one planet, and the multiple planet system with a large mass planet has more chance of detailed follow-up observations, the multiple planet system may be an ...

Post-Quantum Secure ID-Based (Threshold) Linkable Dual-Ring Signature and Its Application in Blockchain Transactions

open access: yesCryptography
Ring signatures are widely used in e-voting, anonymous whistle-blowing systems, and blockchain transactions. However, due to the anonymity of ring signatures, a signer can sign the same message multiple times, potentially leading to repeated voting or ...

On the signature of $z\sim 0.6$ superclusters and voids in the Integrated Sachs-Wolfe effect

open access: yes, 2013
Through a large ensemble of Gaussian realisations and a suite of large-volume N-body simulations, we show that in a standard LCDM scenario, supervoids and superclusters in the redshift range $z\in[0.4,0.7]$ should leave a {\em small} signature on the ISW

Excitability in semiconductor microring lasers: Experimental and theoretical pulse characterization

open access: yes, 2010
We characterize the operation of semiconductor microring lasers in an excitable regime. Our experiments reveal a statistical distribution of the characteristics of noise-triggered optical pulses that is not observed in other excitable systems.
