Abstract:

Utilizing quantum Fourier transformation, this paper proposes an authenticated multiparty quantum secret sharing protocol. In the protocol, d-level single particle is transmitted as the information carrier between the secret owner and all agents. The agents encode their private messages on these traveled particles by two kinds of generalized Pauli operators, and the owner measures the particles and obtains his secret. In the process of reconstruction, the secret can be recovered if and only if all agents collaborate. This paper uses the classic Hash function to authenticate the agent’s identity, and combines the authentication process with the channel eavesdropping detection to improve the detection efficiency of the protocol. This paper discusses the security and authentication of the protocol in detail, which shows that the proposed protocol is safe in theory.

Key words: quantum secret sharing, d-level single particle, identity authentication
