A (t, n) threshold protocol of semi-quantum secret sharing based on single particles
Frontiers in Physics, 2023 Semi-quantum secret sharing is an important research issue in quantum cryptography. In this paper, we propose a (t, n) threshold semi-quantum secret sharing protocol, which combines the practicality of semi-quantum secret sharing protocols and the ...

Is quantum secret sharing different to the sharing of a quantum secret? [PDF]
SPIE Proceedings, 2004 We present an experimental scheme to perform continuous variable (2,3) threshold quantum secret sharing on the quadratures amplitudes of bright light beams. It requires a pair of entangled light beams and an electro-optic feedforward loop for the reconstruction of the secret.

Computational Quantum Secret Sharing
CoRR, 2023 Quantum secret sharing (QSS) allows a dealer to distribute a secret quantum state among a set of parties so that certain subsets can reconstruct the secret, while unauthorized subsets obtain no information. While QSS was introduced over twenty years ago, previous works focused only on existence of perfectly secure schemes, and the share size of the ...

Lattice-based Threshold Secret Sharing Algorithm [PDF]
Jisuanji gongcheng, 2016 The secret sharing algorithm based on the traditional mathematical assumption is difficult to resist the attack of the quantum algorithm.Therefore,a lattice-based threshold secret sharing algorithm is proposed.The basic process of the secret sharing ...

Quantum cryptographic resource distillation and entanglement
Scientific Reports, 2021 We look into multipartite quantum states on which quantum cryptographic protocols including quantum key distribution and quantum secret sharing can be perfectly performed, and define the quantum cryptographic resource distillable rate as the asymptotic ...

Multiparty quantum secret sharing [PDF]
Physical Review A, 2005 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. We take advantage of this multiparty QSSCM scheme to establish a scheme of multiparty secret sharing of quantum information (SSQI),

A Resilient Quantum Secret Sharing Scheme [PDF]
International Journal of Theoretical Physics, 2014 A resilient secret sharing scheme is supposed to generate the secret correctly even after some shares are damaged. In this paper, we show how quantum error correcting codes can be exploited to design a resilient quantum secret sharing scheme, where a quantum state is shared among more than one parties.
