Implementing Quantum Secret Sharing on Current Hardware

open access: yesEntropy
Quantum secret sharing is a cryptographic scheme that enables the secure storage and reconstruction of quantum information. While the theory of secret sharing is mature in its development, relatively few studies have explored the performance of quantum ...

Counterfactual Quantum Secret Sharing

open access: yesIEEE Transactions on Communications
The emerging quantum technology has highlighted the necessity for secure and efficient secret sharing in quantum networks. In this paper, we introduce a verifiable multiparty counterfactual quantum secret sharing (QSS) protocol, enhancing security and efficiency. This QSS protocol utilizes a low-depth quantum circuit to encrypt and decrypt information,

Continuous Variable Quantum Secret Sharing with Fairness

open access: yesApplied Sciences, 2019
The dishonest participants have many advantages to gain others’ shares by cheating in quantum secret sharing (QSS) protocols. However, the traditional methods such as identity authentication and message authentication can not resolve this problem ...

Advance Sharing Procedures for the Ramp Quantum Secret Sharing Schemes With the Highest Coding Rate

open access: yesIEEE Transactions on Quantum Engineering
In some quantum secret sharing schemes, it is known that some shares can be distributed to participants before a secret is given to the dealer. However, it is unclear whether some shares can be distributed before a secret is given in the ramp quantum ...

Quantum function secret sharing [PDF]

open access: yesIACR Cryptol. ePrint Arch.
We propose a quantum function secret sharing scheme in which the communication is exclusively classical. In this primitive, a classical dealer distributes a secret quantum circuit $C$ by providing shares to $p$ quantum parties. The parties on an input state $\ketψ$ and a projection $Π$, compute values $y_i$ that they then classically communicate back ...

Study of secret sharing schemes based on quantum theory

open access: yesTongxin xuebao, 2009
Quantum secret sharing(QSS) which is based on the laws of quantum mechanics,instead of mathematical assumptions can share the information unconditionally securely, according to the form of sharing information, quantum secret sharing can be divided into ...

Quantum secret sharing [PDF]

open access: yesPhysical 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

Security and Fairness in Multiparty Quantum Secret Sharing Protocol [PDF]

open access: yesIEEE Transactions on Quantum Engineering
Quantum secret sharing (QSS) is a cryptographic protocol that leverages quantum mechanics to distribute a secret among multiple parties. With respect to the classical counterpart, in QSS, the secret is encoded into quantum states and shared by a dealer ...

A Novel Quantum Visual Secret Sharing Scheme

open access: yesIEEE Access, 2019
Inspired by Naor et al.'s visual secret sharing (VSS) scheme, a novel n out of n quantum visual secret sharing (QVSS) scheme is proposed, which consists of two phases: sharing process and recovering process. In the first process, the color information of

A Semi-Quantum Secret-Sharing Protocol with a High Channel Capacity

open access: yesEntropy, 2023
Semi-quantum cryptography communication stipulates that the quantum user has complete quantum capabilities, and the classical user has limited quantum capabilities, only being able to perform the following operations: (1) measuring and preparing qubits ...
