Design of Secure Communication Scheme Based on Spread Spectrum Technology and Joint Wavelet Algorithm

摘要:

在信息化技术高度发达的今天,为了适应变化莫测的战场环境对于安全信息通信的高要求,文章在研究探讨水印嵌入检测技术的基础上,利用秘钥产生的扩频码调制水印信息,紧接着通过小波变换对调制后的水印进行信息嵌入操作,而在接收端采用相反的操作对加密信息进行计算机检测后解调恢复,实现信息的隐秘传输;通过实验仿真证明了所提方案可以有效实现对信息的隐蔽传输,其具有很好的安全性,同时对于剪裁攻击具有一定的鲁棒性。

Abstract:

In today's world is a modern information world, in order to adapt to the change constantly battlefield environment high requirement for secure information communication, based on watermark detection technology in the research on spread spectrum watermark information generated by the secret key, followed by the wavelet transform of the modulated watermark information is embedded in the operation. The receiver uses the reverse operation of the encrypted information is demodulated to restore the computer after detection, realize the secret information transmission. The simulation results show that the proposed scheme can effectively realize the covert transmission of information. It has good security and robustness to clipping attacks.
