Abstract

The article introduces a novel verifiable (k, n)-threshold dynamic quantum secret sharing scheme that addresses the limitations of classical secret sharing in the quantum era. By using a d-dimensional GHZ state and asymmetric binary polynomials, the scheme ensures secure secret distribution and recovery. It also incorporates mechanisms to detect and prevent various attacks, such as intercept-and-resend, entangle-and-measure, and Trojan horse attacks. The scheme allows for the dynamic addition and deletion of participants, enhancing its practicality. Additionally, it combines classical secret sharing techniques to securely share multiple secrets efficiently. The proposed scheme stands out by providing a robust solution that can resist participant attacks and ensure the integrity and confidentiality of shared secrets.
