摘　　要：为了提高信息在网络中传输的安全性,需要对网络可逆大容量信息隐藏方法进行研究。采用当前网络可逆大容量信息隐藏方法对信息进行隐藏处理时,存在嵌入信息容量小和信息隐藏安全性低的问题。在结构约束的条件下提出一种实时网络可逆大容量信息隐藏方法,通过加法和减法两个操作构建DNA序列的开始标签和结束标签,采用标签构建法结合开始标签和结束标签得到信息嵌入的最佳位置。通过基于R-LWE的信息隐藏方法设置参数,并对信息进行预处理,根据私钥和公钥对信息进行加密和解密处理,将加密处理后的信息嵌入到最佳位置或将嵌入的信息提取出来,完成网络可逆大容量信息的隐藏处理。仿真结果表明,所提方法的嵌入容量在60bit以上,验证所提方法的嵌入容量大、安全性高。In order to improve the security of information transmission in network,we need to research the network reversible high-capacity information hiding method.This article proposed a method of hiding.real-time network reversible large-capacity information based on structural constraint.At first,the addition and subtraction was used to construct start tag and end tag of DNA sequence,and then the method of label construction was combined with the start tag and end tag to obtain the best position of information embedding.Moreover,R-LWE information hiding method was used to set parameters and preproeess information.Meanwhile,the information was encrypted and deerypted according to the private key and the public key.Finally,the encrypted information was embedded in the best position or the embedded information was extracted.Thus,we completed the hidden processing of network reversible high-capacity information.Simulation results show that the embedded capacity of proposed method is more than 60 bits.Thus,the proposed method has large embedded capacity and high seeurltv.
