    "abstract": "A novel scheme for secure direct communication between Alice and Bob is\nproposed, where there is no need for establishing a shared secret key. The\ncommunication is based on Einstein-Podolsky-Rosen pairs and teleportation\nbetween Alice and Bob. After insuring the security of the quantum channel (EPR\npairs), Bob encodes the secret message directly on a sequence of particle\nstates and transmits them to Alice by teleportation. In this scheme\nteleportation transmits Bob\u0027s message without revealing any information to a\npotential eavesdropper. Alice can read out the encoded messages directly by the\nmeasurement on her qubits. Because there is not a transmission of the qubit\nwhich carry the secret message between Alice and Bob, it is completely secure\nfor direct secret communication if perfect quantum channel is used.",
