The Detection of Cheaters in Thershold Schemes [PDF]

open access: yesSIAM Journal on Discrete Mathematics, 1990
Summary: Informally, \(a(t,w)\)- threshold scheme is a way of distributing partial information (shadows) to \(w\) participants, so that any \(t\) of them can easily calculate a key (or secret), but no subset of fewer than \(t\) participants can determine the key.

Linear Threshold Multisecret Sharing Schemes [PDF]

open access: yesInformation Processing Letters, 2010
In a multisecret sharing scheme, several secret values are distributed among a set of n users, and each secret may have a differ- ent associated access structure. We consider here unconditionally secure schemes with multithreshold access structures. Namely, for every subset P of k users there is a secret key that can only be computed when at least t of

Boolean Operation Based Visual Cryptography

open access: yesIEEE Access, 2019
A ( $k$ , $n$ )-Traditional Visual Cryptographic Scheme (VCS) based on basis matrices encoded a secret image into $n$ shadow images distributed among $n$ participants.

A survey and refinement of repairable threshold schemes [PDF]

open access: yesJournal 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.

Elliptic Threshold Secret Division Scheme

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2009
The new aspect of proactive systems realization was developed based on elliptic curves arithmetic. Neural network model of secret division scheme at elliptic curve is introduced. Prolongation mechanism of the scheme was developed. Neural network model of

Verifiable Threshold Quantum State Sharing Scheme

open access: yesIEEE 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

open access: yesHigh-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.
