Improvement of lightweight threshold group signature scheme
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 ...

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

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.

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. Namely, for every subset P of k users there is a secret key that can only be computed when at least t of

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.
