Quantum secret sharing based on quantum information masking

In this paper, we construct a physical process to mask the d-dimensional quantum state into multipartite quantum systems. According to this masker, we propose a quantum secret sharing scheme to realize a class of special hypergraph access structures. In the distribution phase of the proposed protocol, the distributor wants to share an unknown d-dimensional quantum state and mask the secret state into a multi-party quantum systems. In the reconstruction phase, participants in the authorized set carry out several measurements and a series of appropriate unitary operations on their particles to obtain the original information state. At last, we also analyze the security of our scheme in three primary quantum attacks.

In this paper, we propose a physical process to mask a d-dimensional quantum state into multipartite quantum systems and introduce a quantum secret sharing scheme for a specific hypergraph access structure. In the proposed protocol, the distributor shares an unknown d-dimensional quantum state and masks the secret state into a multi-party quantum systems. Participants in the authorized set reconstruct the original information state through measurements and appropriate unitary operations. The security of our scheme is also analyzed under three primary quantum attacks.
