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 ...

Improving Continuous Variable Quantum Secret Sharing with Weak Coherent States
, 2020 Quantum secret sharing (QSS) can usually realize unconditional security with entanglement of quantum systems. While the usual security proof has been established in theoretics, how to defend against the tolerable channel loss in practices is still a ...

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 ...

Hybrid threshold adaptable quantum secret sharing scheme with reverse Huffman-Fibonacci-tree coding
, 2016 With prevalent attacks in communication, sharing a secret between communicating parties is an ongoing challenge. Moreover, it is important to integrate quantum solutions with classical secret sharing schemes with low computational cost for the real world

A Kind of (t, n) Threshold Quantum Secret Sharing with Identity Authentication
, 2023 Quantum secret sharing (QSS) is an important branch of quantum cryptography. Identity authentication is a significant means to achieve information protection, which can effectively confirm the identity information of both communication parties.

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

Efficient (k, n) threshold semi-quantum secret sharing protocol
Frontiers in PhysicsMost (k, n) threshold quantum secret sharing protocols are fully quantum. The message receivers must be equipped with complex quantum devices so as to prepare various quantum resources and perform complex quantum operations, which may affect the practice

Physical Review Letters, 1999 We investigate the concept of quantum secret sharing. In a ((k,n)) threshold scheme, a secret quantum state is divided into n shares such that any k of those shares can be used to reconstruct the secret, but any set of k-1 or fewer shares contains absolutely no information about the secret. We show that the only constraint on the existence of threshold

Matroids and quantum-secret-sharing schemes [PDF]
Physical Review A, 2010 A secret sharing scheme is a cryptographic protocol to distribute a secret state in an encoded form among a group of players such that only authorized subsets of the players can reconstruct the secret. Classically, efficient secret sharing schemes have been shown to be induced by matroids.
