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.

Unconditional security of entanglement-based continuous-variable quantum secret sharing [PDF]
, 2017 The need for secrecy and security is essential in communication. Secret sharing is a conventional protocol to distribute a secret message to a group of parties, who cannot access it individually but need to cooperate in order to decode it.

Dynamic hierarchical quantum information sharing protocol
网络与信息安全学报, 2016 Quantum secret sharing (QSS) is one important branch of quantum cryptography.Based on the studies of multi-shared quantum bits,a new dynamic quantum bit sharing protocol was proposed.The participation of the shared members is hierarchical in this ...

Standard (3, 5)-threshold quantum secret sharing by maximally entangled 6-qubit states
Scientific Reports, 2021 In this paper, a standard (3, 5)-threshold quantum secret sharing scheme is presented, in which any three of five participants can resume cooperatively the classical secret from the dealer, but one or two shares contain absolutely no information about ...

Communication efficient quantum secret sharing [PDF]
Physical Review A, 2019 In the standard model of quantum secret sharing, typically, one is interested in minimal authorized sets for the reconstruction of the secret. In such a setting, reconstruction requires the communication of all the shares of the corresponding authorized set.

Breaking the rate-distance limitation of measurement-device-independent quantum secret sharing
Physical Review Research, 2023 Currently most progress on quantum secret sharing suffers from rate-distance bound, and thus the key rates are limited. In addition to the limited key rate, the technical difficulty and the corresponding cost together prevent large-scale deployment ...

Quantum Secret Sharing with Error Correction [PDF]
Communications in Theoretical Physics, 2012 We investigate in this work a quantum error correction on a five-qubits graph state used for secret sharing through five noisy channels. We describe the procedure for the five, seven and nine qubits codes. It is known that the three codes always allow error recovery if only one among the sents qubits is disturbed in the transmitting channel.

Quantum strongly secure ramp secret sharing [PDF]
, 2015 Quantum secret sharing is a scheme for encoding a quantum state (the secret) into multiple shares and distributing them among several participants. If a sufficient number of shares are put together, then the secret can be fully reconstructed.

Proposal for quantum rational secret sharing [PDF]
Physical Review A, 2015 A rational secret sharing scheme is a game in which each party responsible for reconstructing a secret tries to maximize his utility by obtaining the secret alone. Quantum secret sharing schemes, either derived from quantum teleportation or from quantum error correcting code, do not succeed when we assume rational participants.
