摘　　要：为降低噪声对秘密信息传输效率的影响,提出一种基于改进乒乓协议的量子隐写协议。利用量子纠缠的特性,通过受控非门实现秘密信息传输。以嵌入过秘密信息的粒子作为载体协议的初始粒子,在执行载体协议步骤的同时传输秘密信息。分析结果表明,该协议具有较好的抗噪声稳健性、隐蔽性和安全性。In order to reduce the influence of noise on the efficiency of secret information transmission,a quantum steganographic protocol based on Improved Bostr m-Felbinger protocol(IBF)is proposed.The protocol effectively utilizes the characteristics of quantum entanglement and realizes secret information transmission by Controlled non gate(CNOT gate).Among them,the particle embedded with secret information is used as the initial particle of carrier protocol to transmit secret information while executing carrier protocol steps.Analysis results show that the protocol has better anti-noise robustness,concealment and security.
