Quantum Secret Sharing with Classical and Quantum Shares

CoRR
In quantum secret sharing, a quantum secret state is mapped to multiple shares such that shares from qualified sets can recover the secret state and shares from other forbidden sets reveal nothing about the secret state; we study the setting where there are both classical shares and quantum shares.

Security of Verifiable Threshold Quantum Secret Sharing With Sequential Communication

IEEE Access, 2019
A verifiable (t, n) threshold quantum secret sharing scheme with sequential communication was proposed recently. In this work, we analyze its security and then give two new participant attacks.

Efficient Quantum Information Hiding for Remote Medical Image Sharing

IEEE Access, 2018
Information hiding aims to embed secret data into the multimedia, such as image, audio, video, and text. In this paper, two new quantum information hiding approaches are put forward.

Quantum Data Aggregation Using Secret Sharing and Genetic Algorithm

IEEE Access, 2020
In the process of data aggregation, intruder nodes and compromised nodes may decrease the system performance. Hence, security plays an important role. Secret sharing is a method to find the compromised nodes.

Threshold Quantum Secret Sharing

CoRR
One crucial and basic method for disclosing a secret to every participant in quantum cryptography is quantum secret sharing. Numerous intricate protocols, including secure multiparty summation, multiplication, sorting, voting, and more, can be designed with it.

Quantum Secret Sharing with Graph States [PDF]

, 2013
We study the graph-state-based quantum secret sharing protocols [24,17] which are not only very promising in terms of physical implementation, but also resource efficient since every player’s share is composed of a single qubit. The threshold of a graph-state-based protocol admits a lower bound: for any graph of order n, the threshold of the ...

Efficient Quantum Private Comparison Based on GHZ States

Entropy
Quantum private comparison (QPC) is a fundamental cryptographic protocol that allows two parties to compare the equality of their private inputs without revealing any information about those inputs to each other.

Continuous Variable Quantum Secret Sharing with Fairness

Applied 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 ...

Integrated semi‐quantum layered communication

IET Quantum Communication
In recent times, secure quantum communication in layered networks has emerged as an important area of study. The authors harness the potential offered by multidimensional states in secure quantum communication with only one quantum participant and all ...

LWE‐based verifiable essential secret image sharing scheme ((t,s,k,n)$( {t,s,k,n} )$ ‐ VESIS)

IET Image Processing
In traditional secret image sharing schemes, shareholders have similar situations, and to recover the secret image, they must be present as many as the threshold.
