摘要
在信息安全传输领域,为弥补密码技术的不足,在分析功能要求的基础上,提出了压缩软件、加密软件和密写软件相结合的信息安全传输方案,给出方案的详细处理过程,并重点设计了密写软件,对其嵌入部分和提取部分的实现过程分别进行了设计说明。实验表明,该方案切实可行,安全性较只使用加密技术有所提高。
In the information secure transfer area,in order to remedy the weakness of cryptogram technology,on the basis of functional requirement analysis,an information secure transfer solution is proposed which integrates compression,cryptogram and steganography softwares,describes in detail the handling process of the solution and emphasises on the design of the steganography software,of which the implementation process of the embedded and extracted parts are specifically described respectively.Experiments show that the solution is practical and is more secure than applying cryptography alone.
