Journal of Cryptology, 2014 A computational secret-sharing scheme is a method that enables a dealer, that has a secret, to distribute this secret among a set of parties such that a "qualified" subset of parties can efficiently reconstruct the secret while any "unqualified" subset ...

Multiparty Quantum Secret Sharing [PDF]
Physical Review A, 2004 Based on a quantum secure direct communication (QSDC) protocol [Phys. Rev. A69(04)052319], we propose a $(n,n)$-threshold scheme of multiparty quantum secret sharing of classical messages (QSSCM) using only single photons.

Controlled Quantum Secret Sharing [PDF]
Physica Scripta, 2006 We present a new protocol in which a secret multiqubit quantum state $\ket{\Psi}$ is shared by $n$ players and $m$ controllers, where $\ket{\Psi}$ is the encoding state of a quantum secret sharing scheme.

Rational quantum secret sharing [PDF]
Scientific Reports, 2018 AbstractThe traditional quantum secret sharing does not succeed in the presence of rational participants. A rational participant’s motivation is to maximize his utility, and will try to get the secret alone. Therefore, in the reconstruction, no rational participant will send his share to others.

Physical Review A, 1998 Secret sharing is a procedure for splitting a message into several parts so that no subset of parts is sufficient to read the message, but the entire set is. We show how this procedure can be implemented using GHZ states. In the quantum case the presence

Security of a kind of quantum secret sharing with entangled states [PDF]
Scientific Reports, 2017 We present a new collusion attack to a kind of quantum secret sharing schemes with entangled states. Using this attack, an unauthorized set of agents can gain access to the shared secret without the others’ cooperation.

Novel Threshold Changeable Secret Sharing Schemes Based on Polynomial Interpolation. [PDF]
PLoS ONE, 2016 After any distribution of secret sharing shadows in a threshold changeable secret sharing scheme, the threshold may need to be adjusted to deal with changes in the security policy and adversary structure.

A New Scheme for Lossless Meaningful Visual Secret Sharing by using XOR Properties [PDF]
Journal of Artificial Intelligence and Data Mining, 2023 In this paper, a novel scheme for lossless meaningful visual secret sharing using XOR properties is presented. In the first step, genetic algorithm with an appropriate proposed objective function created noisy share images.

Visual secret sharing and related Works -A Review [PDF]
مجلة جامعة الانبار للعلوم الصرفة, 2023 The accelerated development of network technology and internet applications has increased the significance of protecting digital data and images from unauthorized access and manipulation. The secret image-sharing network (SIS) is a crucial technique used

Advance Sharing of Quantum Shares for Classical Secrets
IEEE Access, 2022 Secret sharing schemes for classical secrets can be classified into classical secret sharing schemes and quantum secret sharing schemes. Classical secret sharing has been known to be able to distribute some shares before a given secret. On the other hand,
