    "abstract": "Most of the quantum secure direct communication protocol needs a\npre-established secure quantum channel. Only after insuring the security of\nquantum channel, could the sender encode the secret message and send them to\nthe receiver through the secure channel. In this paper, we present a quantum\nsecure direct communication protocol using Einstein-Podolsky-Rosen pairs. It is\nnot necessary for the present protocol to insure the security of quantum\nchannel before transmitting the secret message. In the present protocol, all\nEinstein-Podolsky-Rosen pairs are used to transmit the secret message except\nthose chosen for eavesdropping check.",
