Single-state multiparty semiquantum secret sharing with d-dimensional Bell states

TL;DR

This paper introduces a secure multiparty semiquantum secret sharing protocol using a single d-dimensional Bell state, enabling all parties to collaboratively recover the sender's secret without complex operations.

Contribution

It presents a novel single-state, d-dimensional Bell state-based MSQSS protocol that is secure, efficient, and does not require entanglement swapping or unitary operations.

Findings

Protocol is secure against outside and participant attacks

Uses only one type of d-dimensional Bell state as resource

Does not require entanglement swapping or unitary operations

Abstract

A single-state multiparty semiquantum secret sharing (MSQSS) scheme with d-dimensional Bell states is proposed, which can accomplish the goal that only when all receivers work together can they restore the sender's secret key. This protocol is validated to be secure against both the outside attack and the participant attack. This protocol is adaptive for the d-dimensional system, only employs one kind of d-dimensional Bell states as initial quantum resource and needs neither quantum entanglement swapping nor unitary operations.
