    "abstract": "We present a scheme for quantum secure direct communication with quantum\nencryption. The two authorized users use repeatedly a sequence of the pure\nentangled pairs (quantum key) shared for encrypting and decrypting the secret\nmessage carried by the traveling photons directly. For checking eavesdropping,\nthe two parties perform the single-photon measurements on some decoy particles\nbefore each round. This scheme has the advantage that the pure entangled\nquantum signal source is feasible at present and any eavesdropper cannot steal\nthe message.",
