In quantum bit commitment (QBC), most existed proposals analyze little of communicating an innocent message over noisy quantum channels. These methods are not practical. Based on the information hiding characteristics of quantum steganography, a novel QBC protocal is proposed. An elegant scheme is presented for disguising secret information as quantum noise, and embedding it in stego qubits which encode into a codeword of quantum error-correcting code. The method is proved secure and effective in the presence of noisy quantum channel and it’s a potential eavesdropper. The results of theoretical analysis and numerical simulation show that the proposed scheme has perfect concealing and binding properties. Theoretical analysis proved the validity. The method forms a theoretical basis for the promotion and application of quantum cryptographic protocols.
