Abstract Quantum secret sharing as a privacy‐preserving scheme necessitating collaborative efforts from all participating users to collectively recover encrypted information. This paper introduces a novel dynamic multi‐party to multi‐party quantum secret sharing protocol based on Bell states, enabling secure sharing of secrets among dynamically changing multi‐party. The protocol innovatively employs Bell states combined with simplified local unitary operations, significantly reducing the complexity and enhancing the scalability of practical implementations in quantum communication systems. Particularly, through simulation using IBM's Qiskit framework, its correctness and practicality are confirmed. Security analysis demonstrates that the protocol effectively withstands common attack methods, providing reliability, and security in quantum communication. This research presents a more flexible and efficient solution in the field of quantum secret sharing.Abstract Quantum secret sharing as a privacy‐preserving scheme necessitating collaborative efforts from all participating users to collectively recover encrypted information.

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.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.
