    "abstract": "Base on the idea of dense coding of three-photon entangled state and qubit\ntransmission in blocks, we present a multiparty controlled quantum secret\ndirect communication scheme using Greenberger-Horne-Zeilinger state. In the\npresent scheme, the sender transmits her three bits of secret message to the\nreceiver directly and the secret message can only be recovered by the receiver\nunder the permission of all the controllers. All three-photon entangled states\nare used to transmit the secret messages except those chosen for eavesdropping\ncheck and the present scheme has a high source capacity because\nGreenberger-Horne-Zeilinger state forms a large Hilbert space.",
