Improvement of lightweight threshold group signature scheme

open access: yes网络与信息安全学报, 2020
In order to improve the security and efficiency of threshold group signature in 5G environment, a new scheme was proposed. The core idea was to introduce message token and dynamic identity to improve the freshness of authentication information and ...

A novel nonrepudiable threshold multi-proxy multi-signature scheme with shared verification

open access: yes, 2009
Tzeng et al. proposed a new threshold multi-proxy multi-signature scheme with threshold verification. In their scheme, a subset of original signers authenticates a designated proxy group to sign on behalf of the original group.

An Efficient Threshold Signature Scheme Resistible to Conspiracy Attack [PDF]

open access: yes, 2014
The study presents a threshold signature scheme. While developing threshold cryptography, the concept of threshold signature can accomplish a tradeoff between efficiency in use and dependability of security.

A Novel Threshold Changeable Secret Image Sharing Scheme

open access: yes, 2021
In secret image sharing, the image is divided into several stego images, which are managed by corresponding participants. The secret image can be recovered only when the number of authorized participants is no less than the threshold.

Modified Shamir Threshold Scheme for Secure Storage of Biometric Data

open access: yesComputers
The security of biometric data is a critical challenge in modern information security due to their uniqueness and non-revocability. Compromise of biometric characteristics leads to irreversible consequences; therefore, storing or transmitting them in ...

Dynamic Multi-threshold Metering Schemes [PDF]

open access: yes, 2001
A metering scheme is a protocol in which an audit agency is able to measure the interaction between clients and servers on the web during a certain number of time frames. Naor and Pinkas [7] considered metering schemes in which any server is able to construct a proof to be sent to the audit agency if and only if it has been visited by at least a number,

A Linear Algebraic Threshold Essential Secret Image Sharing Scheme

open access: yesMathematics, 2022
A secret sharing scheme allocates to each participant a share of a secret in such a way that authorized subsets of participants can reconstruct the secret, while shares of unauthorized subsets of participants provide no useful information about the ...

Early Body Mass Index z‐Score Change and Resolution of Severe Malnutrition in Children With Sickle Cell Anemia in a Low‐Income Setting: A Prospective Single‐Arm Extension Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Children with sickle cell anemia (SCA) in low‐income settings are at risk of severe malnutrition, but optimal nutritional management has not been established. We evaluated an intensified ready‐to‐use therapeutic food (RUTF) regimen in children with persistent severe malnutrition after initial treatment and assessed whether early ...
