Abstract
We present a quantum secure direct communication (QSDC) scheme via Greenberger-Horne-Zeilinger state in driven cavity QED. The user can receive different secret messages, and the communication attendant Alice encodes the secret message directly onto a particle which then can be faithfully teleported to Bob using the shared Greenberger-Horne-Zeilinger states. Our scheme is insensitive to the cavity decay. The necessary time for the scheme is much shorter than the Rydberg-atom, therefore atom decays do not need to be considered. The protocol is simple and realizable with present technology. The security of the present scheme is also discussed,and the scheme is secure.
