We propose a scheme for secure quantum message exchanging network following the idea in entanglement swapping. In this scheme, the servers of the network provide the service for preparing the Greenberger-Horne-Zeilinger (GHZ) entangled states as quantum channels. For preventing the eavesdropping, a security checking method is suggested. After the security check, anyone of the authorized users can exchange his/her messages with another on the network securely and directly.


Key words: Quantum secure direct communication, entanglement swapping, quantum communication network PACS.
