| 摘 要： | 为解决电子商务中各种文件的隐秘传输问题,在分析可执行文件特点的基础上,结合空域信息隐藏原理,设计实现了一种带有密钥的.EXE文件隐密传输方法.该方法在密钥的作用下,将.EXE文件的比特流,隐藏在载体图像较低的3个比特位上.方法已采用Matlab编程实现,实验表明采用该方法进行可执行文件隐藏时,嵌入前后图像的PSNR大于30dB,人类的视觉根本无法区分.而且恢复的可执行文件同正常文件一样,其运行未受任何影响.算法的隐藏效果较好,可以满足文件的隐秘传输需要.

| Abstract: | To solve the secret transmitting problem of different files in E-commerce, a secret .EXE transmitting method with key is presen- ted based on the analysis of the characterists of executable files and the information hiding principle. The bit stream of executable file is concealed into the lower 3 bits of the carrier image under the action of a secret key. The results of conceal realized by Matlab program show that the PSNR of the fore-and-aft images is higher than 30dB, between which human could not find the difference by eyesight. The executable ability of resumed files is not reduced during the process of embedding. The effect of this method is good enough to meet the need Of file transmitting in a secret way. |
