Abstract

Summary This study presents a quantum secret sharing (QSS) protocol designed using Grover's search algorithm in a noisy environment. The proposed protocol utilizes Grover's three‐particle quantum state. The proposed scheme is divided into secret information sharing and eavesdropping checking. The dealer prepares an encoded state by encoding the classical information as a marked state and shares the states' qubits between three participants. Using the amplitude‐damping noise and the phase‐damping noise as conventional noisy channels, it can be demonstrated that secret information can be conveyed between participants with some information lost. The security analysis shows the scheme is stringent against malicious participants or eavesdroppers. The simulation analysis is done on the cloud platform IBM‐QE thereby showing the practical feasibility of the scheme. Finally, an application of the proposed scheme is demonstrated in visual cryptography using the GNEQR representation of images.

A Four-Party Quantum Secret-Sharing Scheme based on Grover's Search Algorithm

Deepa Rathi, Farhan Musanna, Sanjeev Kumar

The work presents an amalgam of quantum search algorithm (QSA) and quantum secret sharing (QSS). The proposed QSS scheme utilizes Grover's three-particle quantum state. In this scheme, the dealer prepares an encoded state by encoding the classical information as a marked state and shares the states' qubits between three participants. The participants combine their qubits and find the marked state as a measurement result of the three-qubit state. The security analysis shows the scheme is stringent against malicious participants or eavesdroppers. In comparison to the existing schemes, our protocol fairs pretty well and has a high encoding capacity. The simulation analysis is done on the cloud platform IBM-QE thereby showing the practical feasibility of the scheme.

Multi-dimensional Quantum Secret Sharing Scheme with Noisy Environment

Deepa Rathi, Sanjeev Kumar, Reena Grover

Quantum secret sharing (QSS) is a cryptography technique relying on the transmission and manipulation of quantum states to distribute secret information across multiple participants securely. However, quantum systems are susceptible to various types of noise that can compromise their security and reliability. Therefore, it is essential to analyze the influence of noise on QSS to ensure their effectiveness and practicality in real-world quantum communication. This paper studies the impact of various noisy environments on multi-dimensional QSS. Using quantum fidelity, we examine the influence of four noise models: d-phase-flip(dpf), dit-flip(df), amplitude damping(ad), and depolarizing(d). It has been discovered that the fidelity declines with an increase in the noise parameter. Furthermore, the results demonstrate that the efficiency of the QSS protocol differs significantly across distinct noise models.

Collusion-Secure Semi-Quantum Secret Sharing Scheme using a Quantum Third Party

Santanu Majhi, Nirupam Basak

The security of a secret sharing protocol is compromised if one or more dishonest participants can reconstruct the secret by deviating from the prescribed protocol, particularly when such malicious behavior remains undetected. Semi-Quantum Secret Sharing (SQSS) is a variant of secret sharing in which the participants possess only classical capabilities, such as preparing and measuring qubits in the computational ($Z$) basis, while a quantum-capable third party assists the dealer in generating and distributing quantum shares of a classical secret. The limited quantum capabilities of the participants in SQSS protocols may introduce vulnerabilities to collusion attacks, enabling an assisting quantum third party, in collaboration with a dishonest classical participant, to jointly recover the secret even without detection. In this work, we propose a novel SQSS protocol that eliminates this vulnerability and achieves information-theoretic security against collusion attacks. We further prove that the proposed protocol is secure against a broad class of external and internal attacks. Finally, a comparative analysis demonstrates that our construction advances existing SQSS protocols by simultaneously optimizing qubit efficiency, involves a classical dealer, and resilience against DCNA attacks using basic Bell states.

An efficient (t,n) threshold quantum secret sharing without entanglement

Huawang Qin, Yuewei Dai

An efficient [Formula: see text] threshold quantum secret sharing (QSS) scheme is proposed. In our scheme, the Hash function is used to check the eavesdropping, and no particles need to be published. So the utilization efficiency of the particles is real 100%. No entanglement is used in our scheme. The dealer uses the single particles to encode the secret information, and the participants get the secret through measuring the single particles. Compared to the existing schemes, our scheme is simpler and more efficient.

The Improved Quantum Secret Sharing Protocol Based on Grover Algorithm

Zhuo Ping Yu

Abstract Quantum secret sharing(QSS) is a cryptographic protocol based on the uncertainty principle and quantum no-cloning theorem and is an essential aspect in quantum computing. This paper describes the Grover search algorithm and how to improve QSS protocol by Grover Algorithm. The QSS based on the Grover algorithm is more secure and easier to operate compared to old QSS protocols. Some scientists improved the security of the first QSS protocol based on QSA by changing the check mode. After that, a protocol with quite different procedures was proposed. The improved one enhances the feasibility of the protocol and it could also make sure that the communication is secure from the attacks.

Quantum secret-sharing protocol based on Grover’s algorithm

Li‐Yi Hsu

A marked state can be found with certainty in the two-qubit case of Grover's algorithm. This property is included in the proposed quantum secret-sharing protocol. In the proposed scheme, the sender prepares some initial state in private and then performs a phase shift of the marked state as the sender's bit. Then, the sender sends these two qubits to each of the two receivers. Only when the sender broadcasts the initially prepared state and then the receivers perform the corresponding inversion operation about the average, is the sender's bit faithfully revealed. Moreover, the sender can detect deception using cheat-detecting states. The proposed quantum secret-sharing protocol is shown to be secure.
