Abstract

To solve the problems of updating sub-secrets or secrets as well as adding or deleting agents in the quantum secret sharing protocol, we propose a two-particle transform of Bell states, and consequently present a novel dynamic quantum secret sharing protocol. The new protocol can not only resist some typical attacks, but also be more efficient than the existing protocols. Furthermore, we take advantage of the protocol to establish the dynamic secret sharing of a quantum state protocol for two-particle maximum entangled states.

Dynamic Secret Sharing Scheme for Quantum State

DU Yu-ta

A kind of dynamic quantum secret sharing scheme for single quantum state is proposed based on the two-particle transform,which performs different local operations on different photons of the Bell states. This scheme can resist the typical attack strategies such as the substitute-Bell-state attack,the compound entanglement-swapping attack and the cheating attack from the agent,etc.Meanwhile,the scheme is also high-efficient and can update the sub-secrets and the group of agents dynamically.

Dynamic Multiparty to Multiparty Quantum Secret Sharing Based on Entanglement Swapping of Bell States

J. -C. Li, Ming‐Ming Wang

Abstract To address the challenge of disseminating confidential information from multiple agents to multiple agents, a dynamic quantum secret sharing protocol is proposed for multiparty ( agents in the Group 1) to multiparty ( agents in the Group 2) based on entanglement swapping of Bell states. This protocol accommodates an unequal number of agents in two groups with and enables the addition and revocation of agents in the Group 2 in both the pre‐measurement phase and the post‐measurement phase. In addition, agents in the Group 1 can verify the shares of agents in the Group 2 without the need for a third party, which significantly enhances the security and simplifies the protocol. A comprehensive security analysis demonstrates that the protocol can effectively resist common attacks in quantum communications. The simulation on the IBM's Qiskit framework shows the correctness and usefulness of the protocol. Compared with previous protocols, the protocol is more flexible and practical. Moreover, the protocol based on Bell states exhibits superior performance compared with previous protocols that utilised others entangled states. This study offers a more flexible and efficient solution for advancing the field of quantum secure communications.

An efficient and secure dynamic quantum direct two-secrets sharing scheme

Fulin Li, Tingyan Chen, Shixin Zhu

Dynamic quantum secret sharing occupies an important position in quantum cryptography. In this paper, an efficient and secure dynamic quantum direct two-secrets sharing scheme is proposed based on the GHZ state. The proposed scheme is a one-time sharing of a determined classic message and quantum states. For recovering the secret messages, the agents only need to have the ability to perform X-basis measurements on the particles without performing any unitary operation. When dynamically deleting agents, our scheme only requires the other agents to announce some information without transmitting any quantum. Moreover, the analysis shows that our scheme is able to resist dishonest revoked agent attack as well as a range of other common attacks. Compared with the existing dynamic quantum direct secret sharing schemes, the proposed scheme is more efficient and more secure.

Multiparty Quantum Secret Sharing Protocol with Authentication

Xiaofen Liu, Xuanhui Yan, Zhiqiang Yao

Utilizing the advantage of Bell state,a multiparty quantum secret sharing protocol with authentication is put forward.In the protocol,the deal encodes two classical bits of secret message on the quantum carrier though performing local unitary operation.He splits the secret message into n shares and then distributes them to n agents via entanglement swapping.Each agent makes a Bell state measurement on the particles in his hand,and obtains his piece of secret according to the measurement result.In the process of reconstruction,these n agents declare respectively their pieces of secret,and recover the secret message if and only if they collaborate.At the same time,combining the technology of Hash function,the identities of the deal and the agents are authenticated.Hence,one main goal of designing the presented protocol,two-way authentication,is achieved.Moreover,we analyze the security and authentication of the presented protocol in detail.It is shown that this protocol can stand against the attacks of outside eavesdropper and inside participant,which means that it is secure in theory.In addition,since the Bell state was used at most,as compared with other quantum secret sharing protocols,the implementation of the presented protocol is more feasible in the current technical conditions.

Dynamic Multiparty Quantum Secret Sharing With a Trusted Party Based on Generalized GHZ State

Ri‐Gui Zhou, Mingyu Huo, WenWen Hu +1 more

This paper proposes a dynamic multiparty to multiparty quantum secret sharing scheme, where two distant groups of participants can share the common secrets. In our present scheme, a trusted third party is required to reliably prepare all quantum resources. Each agent only needs to perform the local unitary operations or single-particle measurement completing the process of secret sharing. Secret can be recovered only if all agents cooperate each other. Furthermore, a new agent can be added or deleted from the current scheme with the help of the trusted third party. Finally, security analysis shows that our scheme can resist various common attacks. Compared to former existing researches, our scheme can be more efficient in real application.

Dynamic quantum secret sharing with identity verification based on quantum walks

Lu Feng, Ri‐Gui Zhou, Xiao-Xue Zhang

Abstract A dynamic quantum secret sharing protocol with authentication is proposed based on quantum walks. The protocol can share specific secrets and also update the secret information periodically based on the existing quantum walks structure. Participants can be added or removed while keeping the original secret unchanged. This is more flexible in practical applications. Before the secrets are shared, each participant is authenticated to ensure the legitimacy of all participants’ identities. In addition, the protocol uses single photons as quantum resources, avoiding the complex preparation of entangled states, which makes the protocol more advantageous and potential in practical applications. Security analyses show that the protocol is resistant to collusion attack and other common attacks.
