A survey and refinement of repairable threshold schemes [PDF]

Journal of Mathematical Cryptology, 2018
Abstract We consider repairable threshold schemes (RTSs), which are threshold schemes that enable a player to securely reconstruct a lost share with help from their peers. We summarise and, where possible, refine existing RTSs and introduce a new parameter for analysis, called the repair metric.

Verifiable Threshold Quantum State Sharing Scheme

IEEE Access, 2018
Quantum state sharing (QSTS) is a hot topic in quantum cryptography. However, majority of the current structures cannot resist the participant's fraud well during the initial state reconstruction phase.

Reaching consensus for membership dynamic in secret sharing and its application to cross-chain

High-Confidence Computing, 2023
The communication efficiency optimization, censorship resilience, and generation of shared randomness are inseparable from the threshold cryptography in the existing Byzantine Fault Tolerant (BFT) consensus.

Modified Shamir Threshold Scheme for Secure Storage of Biometric Data

Computers
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]

, 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,

Serological Benefit of SARS‐CoV‐2 Vaccination Relative to Infection in Children With Acute Lymphoblastic Leukemia

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Children with acute lymphoblastic leukemia (ALL) are at risk of severe outcomes from SARS‐CoV‐2 (SCV2). In the post‐pandemic context, where most children have been infected with SCV2, there are limited data on whether vaccination remains beneficial in children with ALL.

Deep Sequencing of FLT3‐ITD Enables Response Evaluation and Post‐Treatment Monitoring in Childhood AML: An Exploratory Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background An internal tandem duplication in the gene encoding Fms‐like tyrosine kinase 3 (FLT3‐ITD) is associated with high relapse risk and poor prognosis in acute myeloid leukemia (AML) and plays a crucial role in treatment decisions. Measurable residual disease (MRD) analysis of FLT3‐ITD during and after treatment has shown prognostic ...
