摘要：

We present a three-party quantum secure direct communication protocol by using Greenberg-Horne-Zeilinger (GHZ) states and entanglement swapping. The proposed scheme realizes authorized parties' secure exchange of their respective secret messages simultaneously and directly in a set of devices. We show that the scheme is secure against eavesdropper's commonly used attacks. We also generalize the protocol to the N-party case by using N-partite GHZ states.
