Authenticated Semi-Quantum Secret Sharing Based on GHZ-Type States

Abstract

As is known to all that entities authentication can provides secure communication for QSS protocol. In this paper, the authors propose a novel semi-quantum secret sharing (SQSS) scheme where identity authentication is adopted to verify the identification of partners in communication based on GHZ-type states. Any related quantum operations can be performed by the quantum Alice, however, classical partners can only perform classical operations on the transmitted qubits as well as unitary transformation. In addition, the paper also shows that the protocol is secure resist some eavesdropping attacks.
