Efficiency identity-based threshold group signature scheme
Tongxin xuebao, 2009 Threshold group signature was used to guarantee the security of the collective decision.To improve the efficiency,a new identity-based cryptography threshold group signature scheme was proposed basing on bilinear pairing and secret sharing.In this scheme,

Threshold Lattice-Based Signature Scheme for Authentication by Wearable Devices
Cryptography, 2023 This paper presents a new threshold signature scheme based on Damgaard’s work. The proposed scheme allows for changing the message signature threshold, thereby improving the flexibility of the original Damgaard scheme.

Multisecret Threshold Schemes [PDF]
, 2007 A threshold scheme is a system that protects a secret (key) among a group of participants in such a way that it can only be reconstructed from the joint information held by some predetermined number of these participants. In this paper we extend this problem to one where there is more than one secret that participants can reconstruct using the ...

The Detection of Cheaters in Thershold Schemes [PDF]
SIAM 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.

Verifiable (n,n) Threshold Quantum Secret Sharing Scheme [PDF]
Jisuanji gongcheng, 2017 This paper constructs a class of verifiable secret sharing scheme based on Chinese Remainder Theorem and Bell states.In the distribution phase,Alice distributes the shares to the participants through the quantum secure channel.In the recovery phase,Alice

Linear Threshold Multisecret Sharing Schemes [PDF]
Information 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.

Threshold-free localized scheme for DC fault identification in multiterminal HVDC systems [PDF]
, 2022 In the future grid scenario, the continuous operation of large-capacity remote power transmission over an augmented DC network is imperative for implementing a reliable multi-terminal high voltage direct current (MT-HVDC) grid or, alternatively, an MTDC ...
