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.

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 ...

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 ...

Dynamic Multiparty Quantum Secret Sharing With a Trusted Party Based on Generalized GHZ State
IEEE Access, 2021 This paper proposes a dynamic multiparty to multiparty quantum secret sharing scheme, where two distant groups of participants can share the common secrets.

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.

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.

Physical Review A, 1999 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 of an eavesdropper will introduce errors so that his presence can be detected. We also show how GHZ

Information Flow in Secret Sharing Protocols [PDF]
Electronic Proceedings in Theoretical Computer Science, 2009 The entangled graph states have emerged as an elegant and powerful quantum resource, indeed almost all multiparty protocols can be written in terms of graph states including measurement based quantum computation (MBQC), error correction and secret ...

Advance Sharing of Quantum Shares for Quantum Secrets
IEICE Transactions on Fundamentals of Electronics, Communications and Computer SciencesSecret sharing is a cryptographic scheme to encode a secret to multiple shares being distributed to participants, so that only qualified sets of participants can restore the original secret from their shares. When we encode a secret by a secret sharing scheme and distribute shares, sometimes not all participants are accessible, and it is desirable to ...

Controlled quantum secret sharing [PDF]
Physica Scripta, 2006 We present a new protocol in which a secret multiqubit quantum state $\ketΨ$ is shared by $n$ players and $m$ controllers, where $\ketΨ$ is the encoding state of a quantum secret sharing scheme. The players may be considered as field agents responsible for carrying out a task, using the secret information encrypted in $\ketΨ$, while the controllers are
