%X The notion of quantum secure direct communication (QSDC) has been introduced recently in quantum cryptography as a replacement for quantum key distribution, in which two communication entities exchange secure classical messages without establishing any shared keys previously. In this paper, a quantum secure direct communication scheme using quantum Calderbank-Shor-Steane (CSS) error correction codes is proposed. In the scheme, a secure message is first transformed into a binary error vector and then encrypted (decrypted) via quantum coding (decoding) procedures. An adversary Eve, who has controlled the communication channel, can't recover the secrete messages because she doesn't know the deciphering keys. Security of this scheme is based on the assumption that decoding general linear codes is intractable even on quantum computers.
