Abstract A controlled bidirectional quantum secret direct communication scheme is proposed by using a Greenberger--Horne--Zeilinger (GHZ) state. In the scheme, two users can exchange their secret messages simultaneously with a set of devices under the control of a third party. The security of the scheme is analysed and confirmed.
