中文摘要：
在量子比特承诺协议中,目前流行的方案没有很好地解决信道噪声的影响,实用性不强。根据量子隐写术对信息的隐藏性,提出一种新的量子比特承诺协议。提出了利用量子信道噪声结合遮盖比特隐藏敏感信息,同时采用量子纠错码的方法克服信道噪声,有效地抵抗了第三方窃听攻击和噪声对信息的影响和破坏。通过理论分析与仿真证明该协议的绑定性和完善隐蔽性;理论证明了方案的有效性,为量子密码协议的推广应用提供了理论基础。
英文摘要：
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.
