摘要
如何在载体(文本、图像、音频)中巧妙地嵌入秘密信息及扩大传输信息的容量一直是研究人员面临的挑战。从量子信息的角度提出了一种新的信息隐藏思想,在不破坏载体数据的情况下构造量子纠缠态实现了秘密信息的隐藏和传输。为了提高秘密信息的传输容量,将经过Schur变换压缩的量子秘密信息编码到纠缠态的相位中进行传输。在比特传输过程中,新协议能够安全隐蔽地发送秘密量子比特信息。接收方可以通过量子傅里叶变换和已接收量子态的测量结果来提取秘密信息并得到无损的量子图像。此外,还给出了提取秘密量子态信息的具体方法,将量子比特转换为经典比特信息,有效地提升了秘密信息传输容量。该方案在不牺牲载体图像质量的前提下,保证了秘密信息传输的安全性。
How to subtly embed secret information in carriers(text,image,audio)has been a challenge for researchers.From the perspective of quantum information,a new idea of information hiding is proposed to construct quantum entangled states to realize the hiding and transmission of secret information without destroying the carrier data in this paper.In order to increase the transmission capacity of secret information,the quantum secret information compressed by Schur transform is encoded into the phase of the entangled state for transmission.During the bit transmission,the new protocol can securely and covertly send secret quantum bit information.The receiver can extract the secret information and obtain a lossless quantum image by using the quantum Fourier transform(QFT)and the measurement results of the received quantum state.In addition,a specific method is given to extract the secret quantum state information and then convert the quantum bits to classical bits,which can effectively increase the capacity of secret information transmission.This scheme ensures the security of the secret information transmission without sacrificing the carrier image quality.
