Verifiable (n,n) Threshold Quantum Secret Sharing Scheme [PDF]
Jisuanji gongcheng, 2017 This paper constructs a class of verifiable secret sharing scheme based on Chinese Remainder Theorem and Bell states.In the distribution phase,Alice distributes the shares to the participants through the quantum secure channel.In the recovery phase,Alice

Quantum function secret sharing
IACR 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 ...

Continuous-variable ramp quantum secret sharing with Gaussian states and operations
New Journal of Physics, 2019 We aim to quantify and mitigate quantum-information leakage in continuous-variable quantum secret sharing (CV QSS). Here we introduce a technique for certifying CV ramp quantum secret-sharing (RQSS) schemes in the framework of quantum interactive-proof ...

CoRRThis paper studies the capacity limits for quantum secret sharing (QSS). The goal of a QSS scheme is to distribute a quantum secret among multiple participants, such that only authorized parties can recover it through collaboration, while no information can be obtained without such collaboration. We introduce an information-theoretic model for the rate

Quantum Secret Aggregation Utilizing a Network of Agents
Cryptography, 2023 Suppose that the renowned spymaster Alice controls a network of spies who all happen to be deployed in different geographical locations. Let us further assume that all spies have managed to get their hands on a small, albeit incomplete by itself, secret,

Quantum Security Computation on Shared Secrets [PDF]
International Journal of Theoretical Physics, 2018 Ouyang et al. proposed an $(n,n)$ threshold quantum secret sharing scheme, where the number of participants is limited to $n=4k+1,k\in Z^+$, and the security evaluation of the scheme was carried out accordingly. In this paper, we propose an $(n,n)$ threshold quantum secret sharing scheme for the number of participants $n$ in any case ( $n\in Z ...

A Novel Quantum Visual Secret Sharing Scheme
IEEE 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

PQSF: post-quantum secure privacy-preserving federated learning
Scientific ReportsIn federated learning, secret sharing is a key technology to maintain the privacy of participants’ local models. Moreover, with the rapid development of quantum computers, existing federated learning privacy protection schemes based on secret sharing ...
