In this paper, we propose a communication protocol called Controlled Bidirectional Quantum Secret Direct Communication (CBQSDC) for mobile networks. In mobile networks, telecom companies assist the agent ensuring both sides could receive the other’s secret messages in the transmission by quantum theory simultaneously. This protocol is based on n-particle GHZ states (Greenberger-Horne-Zeilinger-states) which are transformed to Einstein-Podolsky-Rosen (EPR) pairs by entanglement swapping. GHZ states are used to carry both sides’ messages and entanglement swapping could reduce the number of transmission, so we could decrease the probability of eavesdropping. If any eavesdropper tries to steal dealer’s messages, the lawful participants will perceive it and abort their transmission.
