Abstract

Quantum key distribution is the core technology of quantum communication. In 2012, the Measurement-Device-independent quantum key distribution protocol proposed by Lo et al., referred to as MDI-QKD protocol, can effectively resist detector attacks from eavesdroppers. However, the traditional MDI-QKD only supports two parties, which can no longer meet the actual needs in the era of rapid development of communication technology. Therefore, multi-party quantum key distribution has become one of the current hot spots. This paper proposes a multi-user measurement device-independent QKD method based on the GHZ entanglement state. The GHZ entanglement source is used as the quantum relay, which solves the multi-party communication and greatly improves the safe communication distance.
